Description
Application
The iTHERM ModuLine TM151 is a versatile industrial RTD or TC thermometer designed for use with a barstock thermowell or for integration with an existing onsite thermowell. It is compatible with Endress+Hauser temperature transmitters, which provide enhanced accuracy and reliability. The device can be easily customized by selecting various output options and communication protocols. Additionally, Bluetooth® connectivity is available as an optional feature. This thermometer incorporates cutting-edge technologies such as iTHERM QuickNeck, along with advanced temperature sensor technologies like iTHERM QuickSens and iTHERM StrongSens.
Suitable for a wide range of applications
- Measuring range: –200 to +1,100 °C (–328 to +2,012 °F)
- Pressure range: up to 500 bar (7,252 psi)
- Vibration resistance: sensor element withstands up to 60g
- Enhanced maintenance efficiency: sensor replacement without process shutdown, facilitating easy and safe recalibration of the measuring point
Benefits
-
Second process seal with failure indication: Provides valuable insights into the device’s health status
-
iTHERM QuickSens: Achieves the fastest response times of 1.5 seconds for optimal process control
-
iTHERM StrongSens: Offers unparalleled vibration resistance (> 60g) ensuring maximum plant safety
-
iTHERM QuickNeck: Reduces costs and saves time through simple, tool-free recalibration
-
Bluetooth® connectivity (optional): For added convenience and flexibility
Global certifications: Includes explosion protection compliance with ATEX, IECEx, CSA C/US, and CCC standards
