THERMASGARD
Patented quality product (patent no. DE 10 2015 015 941 B4)
Calibratable temperature measuring transducer with sleeve sensor THERMASGARD
(max. –20...+150 °C / –4...+302 °F), aktivem Ausgang, housing made from impact-resistant plastic with quick-release screws,
with cable gland or M12 connector according to DIN EN 61076-2-101, optionally with ⁄ without 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) with 2-wire connection and I output is available.
The temperature transmitter with remote sensor is used to detect temperatures in liquid and gaseous media e.g. if installed in an
immersion sleeve or as a duct sensor. A direct, permanent use in liquids is possible in combination with immersion sleeves THE.
The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
