Function and design

The temperature sensors are in Pt 500 performance, i.e. resistance 500 Ohm at 0^oC. Different temperatures gives different resistance figures. Pt 500 has a higher resolution on the temperature and a lower energy consumption than, for example, the Pt 100 sensor at e.g. battery operation for connected measuring equipment.

The temperature sensors are also approved for use without thermowells. The sensors are delivered in pairs, with 2 m 2*0,35 mm²shielded cable. The screen is intended to protect against the over inductance from the outside.

Installing

The temperature sensors are mounted with thermowells in flow pipes acc. to illustration.

When extending the cables use multilayer signal cable 2*0.75 mm²(proposedly LiYCY). It is important that the total length of the two cables is equal. However, you should not extend more than one to one acc. to below:

Marking

The sensor cables are marked with red and blue marking for mounting on the flow pipes. The product information is saying the name of the manufacturer, temperature range, PTB approval number, type of sensor and production number.
