We will explain the different types of electrical outputs that are available for transducers and how to wire them. We will also discuss what type of output is best suited for your application.

There are mainly 3 types of electrical outputs which are 4-20mA, amplified voltage, and millivolt. Each one has its own advantages depending on the application.

Let’s go over each one in detail. So you can decide which one works best for your needs.

4-20mA Output Transducers

4-20mA output provides accurate measurements with lower power consumption than amplified voltage. However, it requires additional circuitry. Such as current loops and transmitters in order to work properly, which increases costs compared to other options.

 Amplified voltage Output Transducers

Amplified voltage output provides accurate measurements. However, it requires more power than millivolt output because it uses an op-amp circuit instead of just resistors as the millivolt circuit does.

Millivolt Output Transducers

Millivolt output is typically used when measuring very low pressures or high pressures where accuracy isn’t as important as cost-effectiveness.

What is the use of Pressure sensors

Pressure sensors are devices that measure the amount of force per unit area applied to them. It’s used in many industries to measure the amount of force or weight being applied to it. This can be done with any type of material, including liquids and gases. The most common use for this technology is measuring fluid levels in tanks and other containers where fluids are stored or transported. It can also monitor the flow rate of water, oil, gas, air, steam, and other types of fluids through pipelines. They can even be used on moving objects like vehicles, so you know how fast they’re going at all times!

How its work?

Pressure is one of the most common types of measurement in science and industry. There are different types of pressure transducers, one of the most common is the strain gauge-based transducer. This type uses two metal plates to measure changes in force on them due to applied stress or strain on their surfaces. The resulting change in resistance can be used to determine how much force was acting upon it at any given time. These devices are typically used with other instruments. Such as data acquisition systems and digital multimeters. Including remote locations where they cannot be directly accessed by humans without special equipment or tools. The output signal produced by these devices is often very small and requires amplification.

Design and construction

Transducers can be made from different materials depending on the application. Ceramic is one material that can be used for these sensors because it has high stiffness and good electrical insulation properties. The ceramic pressure sensor consists of three main components.(1) A circular diaphragm clamped at its edge onto a rigid ring, which forms the cavity. (2) An electronic circuit consisting of thick-film resistors or capacitors. (3) A base substrate with electrodes attached to form Wheatstone bridge circuitry.

The three-dimensional construction of the ceramic sensor provides excellent stability under static load conditions. Even maintaining low sensitivity to shock loads when compared with other types of sensors. This makes them ideal for use in harsh environments where mechanical shocks are common occurrences. In addition, they have better performance than metal foil-type sensors when exposed to elevated temperatures up to 200 °C.

Types of Pressure Sensing Devices

Apart from price there are many factors to be considered according to the applications they will have. Several factors help determine the type of equipment they need:

  • Pressure: You must know the range of pressure to be measured. Especially the maximum, to have the best results in measurements and efficiency. The diaphragm, accessories, and welds must be compatible with the media where they will be installed.
  • Both the ambient and process temperatures must be known to be compensated to avoid variations in the transducer reading.
  • Environment: The environment where the transducers operate should also be closely examined. Factors such as humidity, temperature, and dust should consider when selecting the type of equipment.
High temperature transmitter

High-temperature transmitters are the key component for monitoring and controlling the pressure of a fluid in many industries. They usually have a small diaphragm that opens or closes according to the pressure levels that are preprogrammed. Due to their operation, they are often confused with pressure transmitters since they perform similar functions.

The transducer or transmitter cannot control the pressure. They only measure the pressure variation as electrical outputs. It included milliamps, voltage, millivolt, resistance, etc.

Capacitance pressure transmitter

There are various kinds of pressure-sensing technologies or sensing principles capable of transducing pressure into a measurable and standardized electrical signal. The most common are strain gauge, capacitance, pressure potentiometric.

From our store, you will find a wide range of products. Those will adapt to various industrial needs, with the best quality and price ratio.

Strain Gauge

Strain gauges use when the pressure range is low and to measure differential pressure. They can measure up to 1,400 bar and operate at temperatures up to 500 ° C, with an accuracy that varies between 0.1 and 0.25%. The pressure trainers have been designed for use in low vacuum research. There are models to measure absolute, gauge, or differential pressure. They can be found in various ranges up to 700 bar and can operate at very high temperatures.

Resonant Wire

Resonant wires have a wire held by a static member at one end and by the sensing diaphragm at the other end. A change in the pressure of the process includes the tension of the cable. In turn, modifies the frequency of resonance. They allow gauge pressures up to 420 bar with high precision and are the most versatile on the market.


Potentiometric provides a simple method. They are the smallest and can be installed in very tight spaces, and they are the most economical models. They can detect pressures of up to 420 bar and have good precision. They are the ones that environmental and temperature variations can most influence.

Types and Operations

According to their operation, four different types of sensors are distinguished. Those are Resistive, Piezoresistive, Capacitive, Piezoelectric,etc

Micro Differential Pressure transmitter
Micro Differential pressure sensor

The activity with resistive pressure sensors base is on the variation of the resistance by the deformation as a process of the pressure. This degree attraction of the conductor will leads to the increase the length and reduces the section surface. That causes a rise in electrical resistance since the specific resistance remains constant.

A base body uses to form this operational attainable. That body features a deformation during a controlled manner. It subjected to pressure and typically consists of an agent membrane in one amongst its components.

During a pressure electrical device sensing element, the deformation worth measures with meander-type metallic electrical conductors. These perform as strain gauges, typically situated within the growth space and also the upset space.

The piezoresistive sensors operate by an analogous principle of resistive sensors. They disagree by mistreatment semiconductors like strain gauges. These gauges change variations in specific resistance because of deformation. In these, the electrical resistance varies proportionately with the actual resistance. The metallic tapes may be placed in any material. The semiconductors incorporate as microstructures within the membrane.

Types in terms of pressure measurements

Pressure sensors are also classified in terms of the type of pressure measurements. They gauge any device operates as a result of the pressuring-sensing technology. During this regard, there are three ways to measure pressure: differential, absolute, and gauge.

Differential Pressure Transducer

Differential transducer

They are used in the industrial field to determine the pressure difference between two different points. These transducers evaluate the pressure through a process known as inferential measurement. This measuring method calculates the pressure or particular variable by measuring other variables which makes the calculation of pressure much easier.

According to this, absolute pressure and gauge pressure can also be considered as differential pressure. Those are mostly used in areas where the flow rate has to be calculated.

Absolute or Vacuum Pressure Transducer

The absolute sensor measures the pressure that is completely in an ideal vacuum with no other products. For this type of pressure measurement, the reference point is absolute zero. Hence, the comparison according to the pressure change is out of the question. As it does not have connection with any external system, the pressure measurement is not affected by any atmospheric pressure changes or any other factors. The absolute transducers are widely used in superior industrial applications like vacuum pumps, liquid pressure calculation, industrial packaging, and process management. Also, for applications like measuring device measurements for weather.


Pressure transmitters are used in a large variety of industrial and residential sectors for various pressure determining purposes. Numerous industries use pressure-sensitive transportation and storage devices to keep up optimum product conditions, which should be accurately monitored to make sure safe delivery and ultimate application. Laboratories conjointly use pressure sensors to live the relative pressure of vacuum chambers to the atmosphere.

It is also used in the filtration system for monitoring. Generally, the liquid and gases that pass through the filtration system include dust particles which will lead to obstruction to the flow. Some applications cannot allow the passage of contaminants through the filtration system. In such systems, it can be used to detect the gradual pressure drop due to the sediments in the system.

Application of pressure transducer in Variable Frequency Drive

Absolute Pressure sensor

Variable frequency drives, or VFDs, controls the electrical motor by modifying the input frequency to the electrical motor.  Transducers monitor the pressure at the pump outlet and send electrical variable signals to the VFD to control the speed as preprogrammed.

Pressure sensing devices are used for VFD speed management in machinery and industrial plant automation.

In order to be an effective and efficient tool for machine automation, transducers must be able to work with a variety of media.
