THERMASGARD
Calibratable temperature measuring transducer with sleeve sensor THERMASGARD
output, rugged housing made from stainless steel V4A with cable gland or M12 connector according to DIN EN 61076-2-101. 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. The measuring transducer is factory-calibrated. Adjustment ⁄ fine adjustment by the user is possible (zero point offset is adjustable). A
direct, permanent use in liquids is possible in combination with immersion sleeves THE (see chapter Accessories). The sensor is factory-calibrated;
an environmental precision adjustment by an expert is possible.
