ECHANICAL DESIGN

THERMOCONT field device incorporating Pt 100 sensor is2-wire temperature transmitter with 4 … 20 mA analogueoutput or transmitter/indicator if equipped with plug indisplay. Intrinsically safe version of each model is availablein ordinary or flame-proof housing.The measured temperature can also be transmitted by Hartcommunication.Intelligent electronics and HART communication providesfor remote programming, error monitoring and indication.The instrument is suitable mainly for temperaturemeasurement of liquids in tanks and pipes and free flowingor lumpy solids, but temperature gauge for rooms is also available.The PFA coated stainless steel probe makes measurementof very aggressive materials also possible.As special version of the unit a remote transmitter is alsoavailable which can be connected to a standard Pt 100 sensor through a simple 4-wire cable. The complete unit consists of the following four parts: • Probe (incorporating the Pt100 sensor) • housing • potted electronics • plug-in display moduleThe Pt 100 sensor is built in the probe, which is inside the protection tube (dual tube design). The protection tube is made of stainless steel.A wide range of tube length and process connections makesproper selection easy. High temperature version unit is equipped with heat dissipation ribs on the protection tube. Housing of the electronics is either of injection mouldedplastic or made of aluminium also in Exd version.The window of the cover provides for the visibility of the plug- in 6-digit LCD display. Different designs facilitate reading of the measured value i.e.reading from above or from the side and the relevant modelshould be selected before ordering. Basic design is for reading from above. Cable for electric connection can reach the screw terminalson the potted electronics through the conduit of the housing.
