Most frequenly used temperature probes are cable temperature probes.
Maximum operating temperature of the cable probe is determined by isolation of connectin cable and built-in temperature sensor.
Cable temperature sensors are selected according to the different environmental conditions in which the sensor is mounted. Conditions to consider are primarily the maximum temperature to which the probe will be exposed and the way the probe will be mounted to the measurement site.
Temperature cable probe is constructed of:
– connectiong cable, insulation of which determines operating temperature range of the cable probe
– protection tube (stainless steel tube), in which the temperature sensor is built
– temperature sensor ( Pt100, Pt1000, KTY, thermistor, etc.), which is coupled with the connection cable and inserted in the protection tube
The most inexpensive probes are type OK, with PVC insulated connection cable and are designed for temperature range from -10°C to 110°C.
For higher operating temperatures we can use temperature probes from OK family with connection cables insulation made of temperature-durable materials (silicone, teflon, fiberglass with steel overbraids etc.) and can be used for temperatures up to 400°C. These probes are usualy installed in a protective sleeves which are usually already a part of a storage tanks, piping, furnaces, etc.
For other mounting requirements we produce screw-in cable probes – type AK and BK and probes with welded mounting hole – type CK.
For on-pipe installation we recommend contact cable probes – type KN with flexible clamp – type KNN.
For temperature measurements in injection molding machines (injection presses) and extruders we recommend the use of the cable probe with bayonet connection – type BJ, which enagles good heat transfer through adjustable spring pressure.
We also offer production of tailor-made temperature cable probes which are custom made to comply with customer’s specifications.
