Model THT
Temperature Sensors
The Data Industrial THT
temperature sensor
provides accurate remote
temperature sensing for
use with Data Industrial
Series 340, 1550 and 2300
Btu meters 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).
