Baumer ZPPW Piston Pressure Switch

A. Product Overview

The Baumer ZPPW piston pressure switch is a robust industrial pressure switch designed for high pressure monitoring, control and safety applications. It uses a piston type sensing mechanism to detect pressure changes and operate an electrical switching contact when the set pressure point is reached.

This model is suitable for pressure ranges from 5 to 600 bar, making it useful for hydraulic systems, compressors, pumps, process equipment and high pressure industrial lines. With 1.0 percent FSR repeatability, the Baumer ZPPW provides reliable and consistent switching performance in repeated operating cycles.

The pressure switch is available with 1 or 2 microswitches SPDT, allowing single point or dual point pressure switching. It has a switch rating of 15 A at 250 VAC and 0.2 A at 220 VDC, making it suitable for control panels, alarm circuits and equipment interlocking. The unit is built with an AISI 316L stainless steel sensing element, die cast aluminum housing and IP66 protection class for demanding industrial environments.

The Baumer ZPPW supports 3/8 inch and 1/2 inch BSP and NPT process connections and can be supplied with accessories such as snubber, chemical seal and cable gland.

B. Working Principle

The Baumer ZPPW piston pressure switch works on a mechanical piston sensing principle. Process pressure enters through the pressure connection and acts on the internal piston assembly. As pressure increases, the piston moves against a calibrated spring mechanism.

When the process pressure reaches the adjusted set point, the piston movement actuates the internal SPDT microswitch. The microswitch changes its contact position and sends an electrical signal to a control circuit, alarm system, motor starter, pump panel or safety interlock system.

When the pressure falls below the reset point, the piston returns to its original position and the microswitch changes back. This mechanical operation allows the switch to provide dependable pressure based control without requiring electronic pressure output.

The availability of 1 or 2 SPDT microswitches makes the Baumer ZPPW suitable for applications where one pressure limit or two pressure limits need to be monitored.

C. Why It Is Used

The Baumer ZPPW piston pressure switch is used to monitor and control high pressure conditions in industrial systems. It helps protect equipment, improve process safety and automate pressure based operations.

It is commonly used for:

High pressure hydraulic system monitoring
Pump start and stop control
Compressor pressure control
Pressure alarm and trip applications
Industrial safety interlock systems
Process line pressure monitoring
