Amphenol Advanced Sensors T3400 series
Amphenol Advanced Sensors announces T3400 series refrigerant leak setection sensor
Telaire’s T3400 series refrigerant leak detection sensors can identify refrigerant gas leaks by assessing the thermal conductivity of a specific gas mixture. In the event of a refrigerant discharge, the variation in refrigerant concentration in the air results in changes in the thermal conductivity of the gas mixture which can be measured by the micro TCD sensing element. As compared to competing detection technologies, thermal-conductivity-based detection offers the benefits of superior long-term reliability and resilience in harsh operating environments.
The T3400 series uses second- generation MEMS thermal conductivity sensor featuring a patented “heat transfer cavity” that achieves highly sensitive and repeatable thermal conductivity measurement by eliminating possible occurrences of natural convection inside the cavity. Because the thermal conductivity measurement is accomplished completely inside the sensor chip, maximum miniaturization can be realized at the device level. To account for changes in thermal conductivity due to humidity and barometric pressure variations, the T3400 series incorporates a relative humidity sensor and a barometric pressure sensor for compensation.
The fully calibrated T3400 series sensors provide Mobus communication, packaged in a robust IP54 rated enclosure.
