Pressure switches are used in a wide variety of industrial, commercial, and laboratory applications. These switches help to control the pressure of a system and ensure safety.

Omega Engineering offers a variety of general purpose, electronic, mechanical, industrial, heavy duty, and OEM pressure switches in gauge, vacuum, and differential ranges with ultra low-pressure options. With a variety of features like adjustable deadbands, relays, and alarm outputs, these switches are reliable and easy to use. Omega's pressure switches are designed to withstand harsh environments and high temperatures.

Frequently Asked Questions

While a standard pressure switch monitors simple pneumatic or hydraulic levels, a process switch is often a more robust, industrial-grade device designed for complex automation. HK Calibrations provides both types to Australian facilities, ensuring you have the right hardware to trigger alarms, shut down motors, or initiate safety interlocks based on precise real-time pressure data.

Process switches act as critical safety "watchdogs" in manufacturing and chemical plants by detecting over-pressure or under-pressure conditions. HK Calibrations stocks high-reliability switches that can automatically trip an Emergency Shutdown (ESD) system, protecting your Australian workforce and preventing expensive damage to turbines, boilers, and pipelines.

Yes, our collection includes specialized differential pressure switches that monitor the difference between two points, such as across a filter or chiller coil. HK Calibrations supplies these to Australian building managers and HVAC technicians to provide "filter-blocked" alerts or to prove flow in water-based cooling systems, ensuring optimal energy efficiency.

Solid-state (electronic) switches offer superior cycle life, high vibration resistance, and on-site programmability for setpoints and hysteresis. HK Calibrations provides these advanced electronic switches to Australian mining and heavy industry sites where extreme reliability is required and mechanical wear must be minimized.

Absolutely. We stock a range of heavy-duty, explosion-proof, and NEMA-rated switches specifically engineered for volatile environments. HK Calibrations ensures that Australian oil, gas, and petrochemical operators have access to certified switches that prevent electrical sparks from igniting surrounding flammable gases.

To ensure that safety setpoints haven't drifted due to mechanical wear or environmental factors, we recommend professional calibration every 12 months. HK Calibrations offers expert 48-hour turnaround calibration services across Australia, ensuring your switches remain NMI-traceable and fully compliant with ISO quality and safety standards.
