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.
Our partner, Johannes Hübner Fabrik elektrischer Maschinen GmbH, as a specialist for customised encoder solutions, can serve almost all requirements of heavy industry. The electronic limit speed switches offer a long service life as well as high reliability.
|Series||Type||Output signal / interfaces||Monitoring of|
|EGS 2 / EGSHJ 2||Solid shaft (flange) | Hollow shaft||Switching output||Overspeed or stillstand|
|EGS 40 / EGSH(J) 40||Solid shaft (flange) | Solid shaft (flange / foot) | Hollow shaft||Switching output||Over- and underspeed (programmable)|
|EGS 41 SIL 2 / EGSH(J) 41 SIL 2||Solid shaft (flange) | Solid shaft (flange / foot) | Hollow shaft||Switching output||Speed (programmable)|
The electronic overspeed switches monitor the factory-set speed with high switching accuracy, including low operating speeds.
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.
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.
