ALTF-2

Precise 1-Wire pipe contact sensor for measuring the surface temperature of pipes.

The digital pipe contact sensor ALTF-2 determines the temperature of the medium flowing in the pipe (e.g. the water temperature) via the surface temperature of the pipe and transmits it via a 1-wire network.

The ALTF-2 offers in a robust IP65 housing the simple and precise acquisition and the interference-free digital data transmission of temperature values of liquids in pipes (via the surface temperature of the pipes) via the 1-Wire bus system. No calibration is necessary. Simple wiring of several probes in series, ring (not closed), star or tree with only two, optionally 3 wires Thermal conductive paste is recommended.
