Thermometrics JS8746 Harsh Environment Temperature Sensor has been designed to address all aspects of temperature measurement for HVAC control systems in the container-ship market, in addition to industrial applications, such as compresors, condensing units, heat pumps, air conditioning. Employing materials and build standards that enhance the sensor’s ability to withstand water ingression and degradation by the marine environment, the sensor meets statutory requirements for temperature measurement and performance expectations.
Applications
- Marine container ship applications
- Compressors
- Condensing units
