Lfs-03 Pressure Switch 15-2500mbar
Posted at: Offers to Sell and Export | Posted on: Monday 21 September 2009 1:07 am | Poster last visit: Saturday 14 November 2009 |
Product Description:
LFS-03 can be is applied to detection positive or negative pressure. It can be used as a gauge or differential
pressure switch with almost no hysteresis. If 2 switch points are required, 2 pressure switches with different calibrations should be employed. The method of fixing the tab terminals to the switch body does not allow for absolute air sealing. The switch is therefore not recommended for applications where static vacuum has to be maintained. However, special models with additional pressure spring which allow for the vacuum to be connected to the pressure inlet side are available on request.
