Surface contact / tube contact temperature measuring transducer THERMASGARD® ALTM2

Calibratable THERMASGARD® ALTM 2 tube contact temperature measuring transducer with eight switchable measuring ranges, external sensor, continuous output, housing made of impact resistant plastic with quick-release screws, optionally with/without display, with cable gland or M12 connector according to DIN EN 61076-2-101.

The surface-contact sensor device 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 and can be fine-tuned to ambient conditions by an expert.
