Room temperature measuring transducer THERMASGARD® RTM1-Modbus
Calibratable room temperature measuring transducer THERMASGARD® RTM1 Modbus With Modbus connection, with ⁄ without optional display for displaying the actual temperature, in an elegant housing made of plastic, with snap-on lid, base with 4-hole attachment, for installation on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for on-wall cable entry.
The calibratable room operating sensor measures the temperature of non-aggressive gases, particularly air. In this case, a setpoint potentiometer is available as an operating element. Optional devices with LCD displays for displaying readings are available for temperature/humidity/dew point or setpoint readings. The displays (LCD) and the retrieval of measurement and control values are triggered via the Modbus interface.
