Instruction manual switches with circular electronic unit 06 December 2021
Liquid switches
What can happen if the switch is installed outside the recommended temperature range
The HB-products web page has temperature specifications for the switches, and these will be different from the recommended
temperature specifications. The switches will operate outside the recommended range but will not be optimal. For oil switches
the switch point will change with temperature and this means there is a risk that the switch will not detect oil or detect without
oil. For sensors installed in low temperatures condensation might occur and water run into the connection between the
mechanical and electrical unit. This might disturb the measurement. Sensors designed for low temperatures has treaded union
which is waterproof.
