Electronic overspeed switches

Monitoring speed and zero speed under extreme ambient conditions.

Heavy industry places tough demands on the reliability and service life of the utilized components. Experience shows that mechanical overspeed switches, which are still used in many industrial plants for overspeed protection purposes do not fulfil all requirements with regard to safety, accuracy and reliability. For instance, these devices often exhibit low resistance to shock and vibration, limited switching accuracy as well as requiring speed increasing gear for low switching speeds.

The EGS series of electronic overspeed switches from Johannes Hübner Giessen are the ideal solution for heavy-duty applications that demand the highest levels of precision and reliability. These devices make it possible to monitor both overspeeds and underspeeds across the complete speed range with utmost precision. Furthermore standstill monitoring is possible.

Product overview

  • EGS 2 / EGSHJ 2

    EGS 2 / EGSHJ 2

    The electronic overspeed switches monitor the factory-set speed with high switching accuracy, including low operating speeds.

  • EGS 40 / EGSH(J) 40

    EGS 40 / EGSH(J) 40

    The electronic speed switches (overspeed switches) monitor as many as 4 programmable speed ranges (overspeed, underspeed and standstill) with a high level of switching accuracy, including at low operating speeds. If a programmed speed is exceeded or is too low, the respective switching output switches.

  • EGS 41 SIL 2 / EGSH(J) 41 SIL 2

    EGS 41 SIL 2 / EGSH(J) 41 SIL 2

    The electronic speed monitors monitor as many as 4 programmable speed ranges (overspeed, underspeed and standstill) with a high level of switching accuracy, including at low operating speeds.
