Limit Switch for Bypass Level Indicator

Features / Description

All GK switches have bi-stable reed contacts. They can be mounted in any
position around the tube of a magnet-controlled level indicator with stainless
steel clamps, however the cable direction should preferably be downward.
The magnet system in the float will switch over the contact whenever the switch
is passed. This permits an arbitrary arrangement of many switches on the tube
surface without the switches disturbing each other. The switch position must
be checked before installation; it can be set with a ring magnet or the float.
The switch hysteresis depends on the distance to the magnet system in the
float and is smallest when the switches are installed closely along the indication
rail.

When larger contact ratings are needed than the reed contacts allow,
suitable relays must be used.

When frequently changing process requirements make a permanent
contact position difficult to handle we recommend to order our
transmitters with 4 ...20 mA output and separate trip amplifier UAS 3,
which enables set point changes by touching a keypad and many
additional features.
