Product features Head temperature sensor - Converter 4 ... 20mA - IP68

DESCRIPTION AND APPLICATION

All of this resistance sensors are designed to measure temperatures by contact ranging up to 400°C. Temperature sensors, combined with a central support or a thermowell, can be used to measure temperature in various applications in an industrial environment.
The sensor variant with welded thread is ideal for direct measurement of fluids in pipes. Sensors respond to protection level IP 68 in accordance with EN 60529. The temperature range of standard operation is between -50 and 400 ° C. The sensors can be used for all control systems compatible with the 4 to 20 mA output signal.
The sensors are designed to operate in a chemically non-aggressive environment.
