Weatherproof Vibration Switches
Weatherproof Vibration Switches
The 3171 is a low cost vibration sensitive switch for the protection of rotating plant and reciprocating machinery. It is adjustable to operate above the normal running levels of vibration, activating alarm or machine shut-down circuits.
Once operated the internal microswitch remains latched until reset. The switch is reset by depressing a reset button on the base of the 3171/MR or by energising momentarily an electrical coil in the 3171/S model.
- The 3171 vibration switch, with its low frequency response, makes it ideal for detection of mass unbalance on most machines.
- It is inherently insensitive to high frequency components and those caused by external knocks, etc.
- Being responsive to vibrations in any directions (dominantly in a horizontal plane) installation problems are minimised.
- Ease of installation on new or existing plant and machinery.
- S.P.C.O, D.P.C.O and D.P.S.T contacts.
- Sensitive to horizontal and vertical planes.
- Electrical connections via 20mm entry.
- Manual or Electric Reset .
- Rated to IP67.
