Flange Resistance Thermometer TP 19 Hengesbach

 The TP19 resistance thermometers with/without transmitter are powerful, rugged devices for process measurements, the food, pharmaceutical and chemical industry, etc., completely made of stainless steel in a sealed design for hygienic applications.

The standard version of the temperature sensor is designed according to Accuracy Class A. Accuracy classes B 1/2, 1/3, 1/10 DIN are optionally available. The measuring inserts are single or double PT 100s, which can be exchanged.

The utilisation of the measuring inserts must be adapted to the requirements with regard to temperature, length, flexibility, vibration resistance and measuring accuracy. Special devices are available for control processes, e.g. tapered sensor tip for particularly short half-value times.

The design according to IP 67 with exchangeable test insert provides access to the measuring point at any time and offers a reliable guarantee for tightness and long operating times, even under extreme operating conditions, as well as saving resources. Programmable 4-20 mA, HART or Profibus PA transmitters can be installed for transmission of the measuring values. The QUICKTEMP series is particularly recommended for measuring points that require calibration.
