Head temperature probe - Converter 4 ... 20mA - IP68 - Max 600 ° C

Delivery in 3 to 5 weeks

Product features Head temperature probe - Converter 4 ... 20mA - IP68 - Max 600 ° C

DESCRIPTION AND APPLICATION

These resistance sensors are designed to measure temperatures by contact ranging up to 600°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 thread is ideal for direct measurement of fluids in conduits. Sensors respond to protection level IP 68 in accordance with EN 60529.

The temperature range of standard operation is between -50 and 600 ° 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.

ACCESSORIES

K 120 central metal support
JPTS 41 stainless steel thermowell
Screw with collar or cutting rings - if different immersion lengths of the temperature sensor are set
