THERMASGARD
Calibratable tube contact temperature measuring transducer THERMASGARD
sensor, continuous output, rugged housing made from stainless steel V4A, with cable gland or M12 connector according to DIN EN 61076-2-101.
The surface-contact sensor is used for temperature detection on lines, pipes (e.g. cold and hot water) or on heating sections for heating system
control. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
