Magnetrol® displacement type level switches offer the
industrial user a wide choice of alarm and control
configurations. Every unit utilizes a simple buoyancy
principle and is well suited for simple or complex
applications, such as foaming or surging liquids or
agitated fluids, and usually costs less than other types of
level switches.

The purpose of the PROOF-ER is to check the operation the switch actuator simulating a high or high-high level
of a displacer control without having to raise the level in condition. When the chain is released, the PROOF-ER

Stainless steel displacers are rated 720 psig @ +100° F Do not use porcelain displacers on non-vented boiler
(50 bar @ +38° C). water condensate systems over +200° F (+93° C). Stainless
steel or Karbate is recommended.
Karbate displacers are limited to a minimum temperature
of +32° F (0° C) and a maximum temperature of +300° F
(+149° C).
