Comprehensive and common temperature measurement technology for almost all branches of industry

Field of application

The RTD thermometer is especially designed for monitoring the room temperature. The device with head transmitter is a complete unit ready for use with enhanced measurement accuracy and reliability compared to directly wired sensors. For ambient temperature measurements indoor or outdoor.

  • Indoor or outdoor ambient temperature measurement

  • Maximum measuring range:–50 to +100 °C (–58 to +212 °F)

  • Degree of protection: IP66/68 (NEMA Type 4x encl.)

Benefits

  • Robust terminal heads according to DIN EN 50446 or stable plastic housings offer optimal protection from extreme ambient conditions

  • Reliable, long term stable and accurate indoor or outdoor ambient temperature measurement

  • Simple and fast wall mounting

  • Optional head transmitter with easy selection: Analog output 4 to 20 mA, HART®, PROFIBUS® PA or FOUNDATION Fieldbus™
