METRIX Vibration switch Model 440

Danh mục: Switches
Hãng sản xuất: METRIX
Tóm tắt:

Vibration switch, output signal 4-20 mA, Frequency range 2-1000 Hz


Vibration switch, output signal 4-20 mA, Frequency range 2-1000 Hz, the 440 switch is CSA approved for Class I Div 2 Groups B,C,D hazardous areas. Its enclosure carries a NEMA 4X rating and uses a 3-hole mounting pattern.


Vibration switches are an attractive solution when all of the following criteria apply:

•  Only one or two measurement points are required on a machine.

•  A fully self-contained approach is desired or required (sensing element, signal conditioning, 

alarming, and outputs). 

•  Sufficient room exists to mount a vibration switch on the machine in the correct location and in 

the correct orientation such that the vibration levels indicative of machinery malfunctions will actually be 

measurable at the switch mounting location.

•  The features of a multi-channel monitoring system are not necessary and cannot be financially 


•  A 4-20mA vibration transmitter is undesirable or impractical because a PLC, DCS, SCADA 

system, or other instrumentation is not available for monitoring the transmitter signal
