Product description

Information

With fluid level indicators EN 656.1, the fluid level can not only be viewed, it can also be monitored using an electric contact.

A float with a magnet is located within the indication range which closes or opens a contact at a certain fluid level (REED switch).

The table values for the maximum allowable pressure are based on the use of mineral oil (according to ISO 3498) at a temperature of 73 °F (23 °C). Use under different conditions will influence the compressive strength and requires prior consultation.

Assembly Instructions for the Cable Connection

Loosen mounting screw and remove connector plug.
Push the contact insert out of the connector housing.
Loosen cable fitting, slip the cable through the connector housing, and connect the wires to the contact insert.
Push the contact insert back into the connector housing in the required position, tighten the cable fitting to relieve strain and to seal the cable.
Push the connector plug onto the contacts of the fluid lever indicator and then secure it with the mounting screw.
