Pressure switches are the simple, robust safety layer of a plant. Electromechanical or solid-state, they change a contact state when pressure crosses an adjustable set-point — starting and stopping pumps, activating alarms, and enforcing safety interlocks independently of the PLC. When a transmitter and its software fail, a hard-wired pressure switch still protects the asset.
A contact that trips when pressure crosses a set-point.
Pressure-based duty control and dead-head/dry-run protection without tying up a PLC analogue input.
High/low pressure alarms wired to the SCADA alarm system or a local beacon.
Independent, hard-wired trips for overpressure protection — a layer that works even if the control system is down.
Field-adjustable trip and reset (deadband) to suit the duty without swapping hardware.
Pair a continuous transmitter (monitoring/control) with an independent switch (protection) so a single failure never removes both measurement and safety.
Tell us the set-point, contact arrangement, media and area classification and we will specify the switch and wire it into your pump control and safety interlocks.
A pressure switch provides a robust, hard-wired layer of protection and control: when pressure crosses a set threshold it changes state, starting or stopping a pump, opening a valve or tripping a system to a safe condition. Because the action is direct and independent of the wider control system, it is well suited to dry-run protection, high-pressure trips and simple sequencing where reliability matters more than fine resolution. We select switches by range, set-point repeatability, wetted materials and the electrical rating of the duty, and install them where they sense the true process pressure. Used well, they add dependable safety and control at modest cost.
