Contact temperature sensor ALF
Technical data
Application
Housing colour: Housing material:
pure white, like RAL 9010
The ALF contact temperature sensors are used for temperature measurement on pipes, tubes or heat carriers. For better temperature transmission between the pipe and the contact sensor, the use of a heat conducting paste is recommended.
PA plastic (30% GF reinforced)
Ambient temperature: Permissible atmospheric humidity: Max. measurement cur- rent (passive): Electrical connection:
−30 … +70 °C
max. 95% rel. humidity, non-condensing
< 1 mA
Screw-type terminals 0.14 mm² to 2.5 mm² only to safety extra low voltage passive max. 30 V AC/42 VDC on pipe by means of cable tie
Mounting/attachment:
