Calibrable room temperature measuring transducer THERMASGARD® RTM 1, with eight switchable measuring ranges (max. –20...+150 °C), active output, in an elegant plastic housing, with clip-on cover, base with 4-hole fixing for installation on vertically or horizontally installed flush-mounted boxes, with a predetermined breaking point for surface-mounted cable entry. Optionally available in a version with a vandal-proof stainless steel housing (top and base screwed together). The measuring transducer converts the measured variables into a standard signal of 0 -10 V or 4...20 mA. The device with automatic output switching (AOS) detects the required output type and automatically switches to the U or I output. Alternatively, a type (2-wire) version with 2-wire connection and I output is available. This room temperature sensor is used to detect temperatures in closed, dry rooms, such as apartments, offices, and commercial establishments.
