Product Heat Technology
EGELHOF produces mechanical sensors and actuators in form of temperature and pressure control elements. Mechanical temperature sensors (sensors) and actuators (bellows and diaphragm) can be separated by a capillary or are integrated as part of a compact control element. In case of a pressure bellow, the mechanical sensor is an actuator at the same time.

EGELHOF has 4 main product groups that are produced in small, medium and large series. Special and individual parts can also be delivered on request:

  • Temperature control elements with bellow (TWB)
  • Temperature control elements with diaphragm (TWG)
  • Pressure control elements with bellow (DWB)
  • Transmitters (WÜB)
Main features are:

  • Function not requiring any auxiliary energy
  • Excellent linearity and low hysteresis
  • Robust and long life
  • Optimal price/performance ratio

EGELHOF tests all of its expansion elements during the development phase with regard to life and switching cycles. A final inspection is carried out on all manufactured parts (test protocol upon request).

In case of developments of new series of temperature and pressure controllers, the customer informs EGELHOF about the requested temperature and pressure ranges, displacement and switching cycles as well as max. dimensions and other characteristics. Then EGELHOF produces initial recommendations / samples and submits a quotation.

Testing, Tests, Simulation
System-oriented testing.
All of the EGELHOF products are tested in our state of the art simulation and test benches during product design.
These test installations are also offered as an external service.
