These resistance-type sensors are intended for contact temperature measurements up to 600 °C. They consist of a measuring stem made of metal and a metal connection head, in which a programmable converter of the type temperature-current 4-20 mA is encased. The sensors are produced in PTS 681 version with a smooth stem or in PTS 691 version with welded-on screwed joint. The sensor stem is made of the stainless steel EN X5CrNi 18-10 (DIN 1.4541), the connection head is made of aluminium alloy. The basic lengths of the measuring stems are 50, 100, 160, 220, 280 and 400 mm. The metal connection head is provided by a cable outlet ending. All these sensor types meet the IP 68 ingress protection requirements according to the EN 60 529 standard.
By combination of the sensor and a stainless steel central holder or a thermowell, which are both available optionally, it is possible to use the sensors for temperature measurements in various applications of the industrial sphere. The sensors can be utilised for any control system that is compatible with the active output 4-20 mA.
The maximum operating temperature range is -50 to 600 °C.
The sensors are designed to be operated in a chemically non-aggressive environment.
