Description
Surface contact / tube contact temperature measuring transducer
THERMASGARD® ALTM1
Calibratable THERMASGARD® ALTM 1 surface-contact temperature measuring transducer (compact version) with eight switchable measuring ranges, continuous output, in an impact resistant plastic housing with quick-locking screws, optionally with/without display, incl. strap.
The surface-contact sensor serves to detect the temperature on lines, pipes (e.g. cold and warm water) or on heating sections for heating control. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
