Isolated sensing of temperature

Jan 2000 Sensors & Transducers

A new range of temperature sensors which includes models that allow the control monitor to be mounted remotely from the sensor probe, has been launched by IFM Electronic. Remote monitor mounting provides an ideal solution where space at the sensing site is restricted and also allows the monitor's integral seven-segment display to be conveniently positioned for easy inspection.

The new range includes TT probes, which are available in standard lengths of up to 500 mm and type TS probes which have integral connecting cables. These probes are complemented by separately mounted type TR control monitors. Also available are type TN sensors with integral control monitors which are a cost-effective choice for standalone applications.

Type TT probes comprise a platinum resistance measuring element mounted within the body of a stainless-steel probe. The control monitor may be remotely mounted and connected via an optional jumper cable or, alternatively, it may be mounted directly on the probe using a patented connector, which offers a robust solution for harsh environments.

Type TS sensors have a 47,5 mm probe with an integral 2 or 5 m connecting cable. The free end of the cable is fitted with an M12 connector which mates directly with the control monitor.

Type TT sensors operate over a temperature range of -40 to +125°C, while TS sensors cover the range from -40 to +150°C. All TS and TT probes have 10 mm diameter type 316 housings and accessories are available to facilitate mounting in various types of standard thermowell. All sensors have an IP67 protection rating.

The control monitors in the range are also IP67-rated. Both the TN integral sensor and TR separately mounted versions incorporate seven-segment displays which provide a continuous readout of temperature, and can be switched easily between Celsius and Fahrenheit. The displays also serve as an aid to setting which is a speedy and simple operation, thanks to IFM's pushbutton adjustment system.

Control monitors are available with dual switching outputs, or with a single switching output plus an analog output. Switching outputs can be set for normally open or normally closed operation and switching hysteresis is fully adjustable. Users can program the analog output as 4-20 mA or 0-10 V and the analog signal can be scaled to cover the optimum range for the application. The maximum and minimum temperatures witnessed during operation are also automatically stored, providing information which is useful when investigating production and maintenance issues.
