Profile: Bailey & Mackey Ltd. is a manufacturer of pressure instruments. Our products serve pressure and temperature sensing applications in many industrial markets including aerospace, automotive, chemical, marine, medical, water, waste, fire, heating & ventilating, and general industries. Pressure gauges, temperature gauges, pressure switches, and pressure transducers are our mainstream products. Our Bourdon tube gauges consist of a formed tube with one end fixed, and the other end free to deflect under pressure. This type of gauge is available for applications where the material of the tube like beryllium copper or stainless steel is compatible with the fluid in the system. Our Piezo resistive pressure transducers use sensors incorporating Piezo resistive circuitry on a silicon diaphragm. The small signal is amplified to give a usable output. Our diaphragm pressure switches consist of either a corrugated metallic diaphragm or a synthetic rubber diaphragm. Metallic diaphragms are versatile as the diaphragm can be treated to meet the majority of chemical applications, whereas synthetic rubber diaphragms are limited to the compatibility of the synthetic rubber. The maximum pressure that diaphragm switches normally operate is 42 bar, but they can be overload protected to 200 bar. Diaphragm pressure switches can also be set to switch in vacuum.
