Head temperature sensor - Converter 4 ... 20mA - IP68
Reference GPTS481R
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.
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
DECLARATION, CERTIFICATION, CALIBRATION
- The manufacturer provides an EU declaration of conformity.
- Calibration - Final metrological control - The manufacturer offers the possibility of supplying the calibrated sensors.
