EFT 7 Self Contained Capacitance Level Indicator


The EFT7 Capacitance Level Indicator is intended for continuous measurement of non-conducting liquids such as fuel oil in tanks. The instrument is completely self-contained, requiring only a supply voltage and having a 4-20mA constant current and a 0-10 Volt signal output.
The EFT7 operates on the principle of a changing electric field caused by the presence or absence of liquid around the electrode. This change after amplification is used to provide the output signals.

An LED indicator shows that the unit is energised.
For tanks from 1m to 6m the electrode is a flexible band type that may be cut to length on site.
For tanks from 200mm to 1m the electrode is rigid and has an integral screen tube.

 

 

 

DMU-03 Pressure Transmitter - 4/20mA


The DMU-03 range of Pressure Transmitters has been designed for the electronic measurement of low viscosity liquids in tanks and air/gas pressures in industrial and marine applications.
The 2-wire loop powered transmitter is simply fitted to a 1/2" BSP connection either on the base of the tank or on the tank outlet pipe and provides a 4-20mA output proportional to the liquid height/pressure in the tank.
The small, compact and robust stainless steel transmitter construction incorporates the latest piezo-resistive measurement technology with excellent stability and accuracy over a long service life 

 

 

 

DMU 08 Pressure Transmitter - Flexible - 4/20mA


DMU-08 Submersible 2-wire Pressure Level Transmitters are designed to measure liquid levels in tanks, boreholes, open reservoirs or process vessels.
The unit is lowered into the tank, borehole, etc. via the integral cable which incorporates a thin ‘breather’ pipe, allowing the backplane of the sensor membrane to remain connected to normal atmospheric pressure.
The greater the liquid head or liquid level, the greater the pressure exerted on the sensor membrane. The sensor electronics convert this pressure into an electrical 4– 20mA current output proportional to the liquid level.
The DMU-08 is supplied and calibrated to specific customer requirements and comes with a 5m Polyurethane connection cable..
Supplied with 1" BSP stainless steel tank gland and in-line cable connector.

 

 

 

 

VarioFox - Level Indicator/Alarm Module


VarioFox Compact, ready-to-connect indication and control instrument with digital display and robust wall mounted housing. With integrated power supply for transducer connection and 2 or 4 relay outputs. 
Connected to an electronic transducer such as the DMU-03 or DMU-08, VarioFox provides a stand alone indication and control system for pressure, temperature or level measurement. VarioFox can be freely configured and is universally applicable.
