THERMASGARD
The calibratable room temperature measuring transducer THERMASGARD
(Baldur 1) with snap-on lid, base with 4-hole attachment, optionally with/without display, for detecting room temperature (0...+50 °C / +32...+122 °F).
International system of units SI (default) can be changed to imperial (via Modbus). The following parameters can be retrieved via Modbus: Temperature,
dew point temperature. Available as a room control unit in various type versions with setpoint potentiometer (%).
A long-term stable, digital temperature sensor guarantees exact measurement results. The sensor is factory-calibrated; an environmental precision
adjustment by an expert is possible. Modbus sensor with galvanically separated RS485 Modbus interface, selectable bus termination resistance,
DIP switches for setting the bus parameters and bus address in a currentless state, internal LEDs for telegram status display and two-line display
(illuminated, in the 7-segment and dot-matrix range, individually programmable).
