hengst Original Rexroth Differential Pressure Signal Transmitter R928028411 WE-2SPSU-M12X1

1. Product Overview

This is a product provided byHengst as the original supporting part for Rexroth.It is aDifferential Pressure Signal Transmitter (Pollution Indicator).It is usually installed on theDouble-barrel High-pressure Filtertomonitor the clogging condition of the filter element.When the differential pressure between the inlet and outlet reaches the set value due to the accumulation of contaminants in the filter element, the signal transmitter will send out anelectrical signalto remind the operator toreplace the filter element in timeso as to protect the hydraulic system from pollution damage.

2. Core Features

• Accurate Monitoring: It can accurately monitor the differential pressure change of the filter element and act reliably when the preset alarm value is reached.

  
  

• Standard Electrical Interface: It is equipped with anM12x1 electrical interfacewhich is a standard connector widely used in industrial sensors and actuators. It has the characteristics ofreliable connection, dustproof and waterproof (usually IP67 grade), which is convenient for quick on-site installation and maintenance.

  
  

• Dual Mechanical and Electrical Indications: It usually integrates avisual indicator (red piston pops out)and anelectrical switch signaldual alarm function. Even if the electrical system fails, maintenance personnel can find the fault through visual inspection.

  
  

• High Reliability: As the original supporting part for the Rexroth system, its design matches perfectly with the filter, ensuring long-term stable operation in harsh industrial environments.

  
  

3. Typical Applications

• Hydraulic Stations: Installed on the double-barrel filters of various industrial hydraulic stations to protect pumps, valves and actuators.

  
  

• Construction Machinery: Used in equipment such as excavators and cranes to protect key hydraulic components.

  
  

• Metallurgical and Mining Equipment: In harsh working conditions with variable dust and loads, it provides reliable pollution alarms for hydraulic systems.

  
  

• Plastic Machinery and Machine Tools: Ensures the cleanliness of hydraulic oil and improves product quality and equipment service life.
