Pressure Switches

Bailey & Mackey's well established range of pressure switches is both reliable and robust, while offering a cost effective solution for most alarm and safety cut-out applications throughout industry.


Specification

Operated by the deflection of a spring metallic diaphragm on a microswitch there are no moving parts or bearings to wear on applications where vibration or fluctuating pressures are experienced. Available in pressure ranges from 5-100 mbar up to 40-400 bar, switches for hydraulic pressures above 40 bar use spring loaded pistons in place of spring diaphragms.

Applications

The Bailey & Mackey range includes pressure switches for operation in special applications such as chemical plants, hazardous areas, and for use with specific fluids such as slurry, sewage, heavy fuel oil etc.

108PQ

Heavy Duty Pressure switch with overload protection. Switch rated at 5 amps at 230V AC. Fixed or adjustable deadband.

Model 12

These pressure switches are used for monitoring system pressure to sound an alarm, operate a warning light, or cut off the electrical supply to a pump or machine as soon as the pressure gets above or below the optimum level. The type 12 pressure switches are particularly suitable for use on compressed air systems, or to monitor water pressures or provide cut-out on pressure failure in lubrications. They can be used on all non-corrosive fluids except for those with high viscosity.

Model 1381

A metallic spring diaphragm deflects under pressure to operate a microswitch. The microswitch is mounted in a bracket which can be tilted to give adjustment over the pressure range. For pressures above 70 bar the movement of a piston under pressure against the spring operates the microswitch. The piston design is only suitable for hydraulic applications.

Model 1382

This series of differential pressure switches are intended for use as general industrial pressure switches. Their reliability, flexibility and robustness enable all applications in all industries to be satisfied. They are used for monitoring the difference between two pressures by giving closing contacts when the difference rises above or falls below the pre-set value.

Model 14

These pressure switches are used for monitoring system pressure to sound an alarm, operate a warning light, or cut off the electrical supply to a pump or machine as soon as the pressure gets above or below the optimum level. The type 14 pressure switches are suitable for use on all non-corrosive gases and non-corrosive fluids except those with high viscosity.

Model 1481

A metallic spring diaphragm deflects under pressure to operate a microswitch. The microswitch is mounted in a bracket which can be tilted to give adjustment over the pressure range. For pressures above 70 bar the movement of a piston under pressure against the spring operates the microswitch. The piston design is only suitable for hydraulic applications.

Model 2381

This series of differential pressure switches are intended for use as general industrial pressure switches. Their reliability, flexibility and robustness enable all applications in all industries to be satisfied. They are used for monitoring the difference between two pressures by giving closing contacts when the difference rises above or falls below the pre-set value.

Model 508

Electrical equipment in Hazardous Areas, where a mixture of flammable gas or vapour which could be ignited by a spark, has to specially constructed and tested. Our Flameproof switches are BASEEFA approved for safe use in Zone 1 and Zone 2 non-mining areas.

Model 518

This series of differential pressure switches are intended for use as general industrial pressure switches. Their reliability, flexibility and robustness enable all applications in all industries to be satisfied. They are used for monitoring the difference between two pressures by giving closing contacts when the difference rises above or falls below the pre-set value.

Model 800

These pressure switches are used for monitoring system pressure to sound an alarm, operate a warning light, or cut off the electrical supply to a pump or machine as soon as the pressure gets above or below the optimum level. The type 14 pressure switches are suitable for use on all non-corrosive gases and non-corrosive fluids except those with high viscosity.

Model 815

This design of pressure switch is suitable for sequence initiation on hydraulic circuits as well as alarm and safety cut-out applications on air, water, oil and other low viscosity fluids that are compatible with stainless steel, nitrile rubber and brass. The movement of a piston under pressure operates a
microswitch via a lever. Piston operated switches are not
suitable for use with high pressure gases.
