Series 1005P1 Pneumatic Liquid Level Switch

Model 1005P1 is a float-actuated, pneumatic switch that opens or closes a block and bleed snap-acting valve. This switch is used as either a high or low level alarm with pneumatic panels. Model P is the same as Model O except a pneumatic 3-way pilot valve is added. This style is for use with a pneumatically operated control valve to control liquids in separators and scrubbers, etc.
