PCH 1220 Electronic Vibration Switch

The PCH 1220 Electronic Vibration Switch provides basic, reliable protection of rotating machinery at a low cost.
 



 
  • Low-cost machine protection
     
  • Accurate, reliable alarm measurements
     
  • Automatic alarm reset
     
  • Simple installation with preset alarm limits






 

Electronic vibration switch vs. mechanical vibration switch

An electronic vibration switch has no moving parts that can become stuck. The electronic signal is also more accurate and has a higher degree of repeatability than a mechanical switch.

 
In choosing an electronic vibration switch such as the PCH 1220, you are opting for the more reliable – and hence safer – solution.

Applications

The PCH 1220 vibration switch is suitable for basic monitoring of rotating machinery such as fans, blowers, and pumps.




 



 

Functionality

PCH 1220 monitors machine vibration within a 10-1000 Hz (ISO 10816-3/20816-3) frequency band and compares the value to the preset alarm threshold.

If the alarm limit is exceeded, the alarm is triggered.

The alarm automatically resets when the vibration level drops below the preset alarm limit.

 

Preset alarm limits

The vibration alarm is preset at delivery, simplifying the installation, and it comes with a delay time of 5 seconds.

 

Casing

The sensor is supplied in stainless steel 1.405 housing with an integrated M8 mounting stud and an M12 top exit connector.




 



 

Options

Temperature

The vibration switch can be fitted with a high temperature adaptor suitable for 90° C radiation.
