Field of application
Cost efficiency, optimal use of space, reliable operation, easy installation and commissioning indicate modern process measuring technology. The temperature switch completely fulfills these requirements. Designed for the safe measurement and monitoring of process temperatures it can be selected between one or two switch outputs as well as one switch output and one standardized analog output. Vibration-proof integrated thin-film sensors guarantee highest operational safety.
Temperature switch for the monitoring, display and control of process temperatures in a range from -50 to 150 °C (-58 to 302 °F). Thermophant T TTR 31- with thread connections or coupling.
Electronic versions:
One PNP switch output
Two PNP switch outputs
2 x PNP switch outputs or one PNP switch output and 4 to 20 mA output (active)
Benefits
Integrated switching electronics for decentralized and economic process monitoring and control
High reproducibility and long-term stability
Function control and information on site thanks to LEDs and digital display
Long-term stable temperature sensor made of platinum (Pt100 class A as per IEC 60751)
High accuracy across the entire ambient temperature range and short response time
Operation and visualisation also with PC and FieldCare or ReadWin 2000 configuration software
DESINA-compliant
