Electro-Mechanical Flow Switches

Supplier: HYDAC International

For many measurement tasks in hydraulics, simple flow meters or flow switches are a cost-effective alternative compared with high precision transmitters such as flow rate transmitter.

Price Guide: POA

The HYDAC Series of Flow Switches is based on a variable area float measurement principle.  The test medium moves a spring-loaded float in the direction of flow, depending on the flow rate. A reed contact is fitted to the outside of the device and is therefore separate from the flow circuit. When the magnet inside the float reaches the preset position, the reed contact switches.

To protect the device from external influences, the switch is encapsulated in a casing designed to allow steplessly variable adjustment. The devices are designed to be capable of monitoring threshold values reliably, even when the viscosity fluctuates. The areas of application include:

  • Central lubrication systems
  • Circulation oil lubrication systems
  • Transformers
  • Cooling systems and circuits
  • Lubrication circuits
  • Hydraulic systems
  • Pumps
  • Welding machines and laser systems
  • Chemical industry
  • Research and development

Special features:

  • Accuracy  ≤ ± 5 % or ≤ ± 10 % FS
  • High level of functional reliability
  • High switching accuracy
  • Switch point infinitely adjustable by the user
  • High pressure resistance
  • Threaded connection
