1. Introduction
P941, P942 is a pressure switch product with a built-in micro switch, and is so designed
that it can be used for corrosive fluid or high pressure process.
The switch is divided into a sensor part under pressure, a control part that regulates
the set value and inflow pressure, and a micro switch that gives contact output.
Micro switch is a high-precision product designed so that it can be operated by
minute pressure change, and has various rated current values. Please correctly use
this product after having thorough knowledge of this instruction manual that states
how to use it respectively in case of intending to use this product.
2. Features
This product can be used for turning on an abnormality alarm or warning light, or
process control according to ON-OFF signal in case of reaching the set pressure.
And it cannot be used in explosion proof area.
