VEGASWING Liquid Level Switches

Many float switches are installed on critical applications and they can cause concern regarding whether they will operate when required. There is the possibility they may become stuck and it is difficult to test them in situ to prove they will operate when required. The vibrating level switch provides a fail safe reliable alternative to float switches and due to the way they operate they generate a fault condition should process build-up on the switch.

The VEGASWING tuning fork is SIL capable and has the best PFDav Reliability figures in the market, when compared to other tuning fork devices, thus ensuring maximum reliability. Many sites have a significant installed base of old ‘Mobrey’ float switches with the ‘A’ type flange fixing. To make upgrade of these devices as straight-forward as possible, the VEGASWING can be ordered with this ‘Mobrey A’ flange fitting as standard.

VEGASWING can use existing cables, while the two-wire mA output of the VEGASWING can connect directly into an analogue channel of a control system. Alternatively, the VEGATOR 636Ex barrier mounted in a panel can provide both relay and transistor outputs to digital inputs. The VEGATOR also has a test button on the front of the unit, to perform a function test on the VEGASWING level switch, which can form part of the
proof-testing protocols.
