DMU 03

The DMU 03 range of pressure transmitters provides an electronic measurement of low-viscosity liquid in tanks and air/gas pressures in industrial and marine applications. The 2-wire loop-powered transmitter is fitted externally at the bottom or lower side of tank and provides a 4-20/mA output proportional to the liquid height/pressure in the vessel. Of stainless steel construction, and incorporating the latest piezo-resistive measurement technology, the DMU 03 has excellent stability and accuracy over a long service life

DMU 08 / 09

A submersible 2-wire pressure level transmitter of stainless steel construction designed to measure liquid levels in tanks, bore holes, open reservoirs, and process materials. The unit is supplied with integral cable which incorporates a breather tube and provides a 4-20mA output. For chemical applications, special, coated cables can be provided and the DMU 09 with PTFE-coated membrane can be supplied for applications with chemicals which attack stainless steel.

TDR Switches

MicroTREK H

MicroTREK level gauge operates on the well known TDR (Time Domain Reflectometry) principle. Micropulses are sent along a probe guide at the velocity of light. On reaching the product surface, the pulse is reflected. The time taken for this to happen is then converted into 4-20 mA current and HART signals.
As measurement is independent of dielectric, temperature, pressure and density variations, the MicroTREK can be used on heavily dusting applications; turbulent product surface, vapour and light foam have no effect on results. Suitable for level metering of liquids, powders and granular mediums

Level Switches

Conductivity Switches

ELT 68

The ELT68 is a special-purpose conductivity level switch with a very low resistance range for use with highly conducting liquids in dairies, breweries, ice-cream and other liquid food plants. Unaffected by foam or viscous liquids the unit can be used with either one sensing probe as a single point level switch or two sensing probes for pump/solenoid control. A built in ‘fail-safe’ selector and suitable for interface detection in pipes between e.g. beer/water, milk/water, caustic/water etc.

ELT 68C

A self-contained all-in-one level switch designed for use with conducting liquids in dairies, breweries, ice-cream plants etc. where dense foam can cause problems with general purpose conductivity level switches. The ELT68C is capable of differentiating between dense layers of foam and the actual liquid surface which renders the unit capable of interface detection in pipes. A special feature of the ELT68C includes a built-in fail-safe selector switch, red and green LED indicators and a hygienic welding gland.

ELT 8

The ELT8 is designed for use with electrically conducting liquids such as water, sewage etc. The unit can be used with either one sensing probe for high or low level, or two sensing probes for the automatic starting and stopping of pumps.
