THERMASGARD
Patented quality product (patent no. DE 10 2015 015 941 B4)
Calibratable room temperature measuring transducer THERMASGARD
+32...+122 °F), 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, optionally with potentiometer and/or display.
The standard display can be changed from SI [°C] to imperial [°F] units via DIP switch. The measuring transducer converts the measured
variables into a standard signal of 0 -10 V or 4...20 mA. The unit with Automatic Output Switching (AOS) detects the required output type
and automatically switches to U or I output. Alternatively, a type version (2-wire I) with 2-wire connection and I output is available.
This room temperature sensor is used to detec temperatures in closed dry rooms such as flats, in offices and business facilities.
The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
