SDC-T1 - Duct Mounted


Active temperature sensor for duct mounting

The SDC-T1 measures the temperature by the use of a precision sensing element. The microprocessor samples the temperature once per second. It calculates an averaging signal over a preset number of seconds and generates an output signal based on lower and upper signal range values.

 The transmitter is available with or without a display.
