The new series S4634 and S4635 contact gauges have electrical limit contacts and pressure indication and can be used anywhere that processes are controlled and a local indication is needed for monitoring vessel pressures.
Only a single device and connection is needed for the switching operation and to monitor pressure. Set-point adjustment is carried out in the pressure-less state, dispensing with the need for complex adjustment in several pressure cycles. The gauges are housed in a stainless steel case. They fulfil the most stringent sealing requirements and have either one or two switched outputs and a 270-degree pressure dial.
The new series S4150 and S4250 mechanical pressure switches are available in a membrane or piston version, and offer the highest precision and resilience. The switches convert pneumatic and hydraulic pressures into electrical signals, and can be used for monitoring and control of process sequences. They can be used in media such as compressed air, neutral or self-lubricating fluids.
