Model THT temperature sensor
The model THT temperature sensor provides accurate remote temperature sensing for use with series 340 BN/MB Btu transmitter, 3050 series monitor and other building automation applications.
The THT includes unique mounting hardware incorporating an isolation valve allowing the temperature probe to be “hot tapped”, or installed in a working pipeline without shutting down or draining the line. This hot tap capability allows temperature sensors to be retrofit to existing pipelines at a fraction of the cost of thermowell installations. For Btu measurement or submetering applications, THT temperature sensors should always be installed in pairs to match their reaction time to temperature change.
The THT sensor features a precision 10 KΩ thermistor element encapsulated with a temperature conductive compound within a 316 stainless steel probe. These two-wire devices have a thermal accuracy of ± 0.36° F (0.2° C).
The series feature a six-bladed impeller design with a proprietary, non-magnetic sensing mechanism. The impeller shape coupled with the absence of magnetic drag provides accuracy and repeatability throughout the flow range of the sensors. As the liquid flow turns the impeller, a low impedance square wave signal is transmitted with a frequency proportional to the flow rate.
