Industrial pressure switches may have a calibrated scale and pointer to show the set point of the switch. A pressure switch will have a hysteresis, that is, a differential range around its setpoint, known as the switch's deadband, inside which small changes of pressure do not influence the state of the contacts. Some types allow adjustment of ...

The first design, codenamed "Puma" during its development, replaced the older Endura-D unit which had been around since 1984. Commercial versions of the Puma unit replaced Ford's older "2.5Di" type unit used in the Transit , and many other manufacturers' vehicles - most notably the London Taxi and in the Land Rover Defender .
The IBM 8000 series was a proposed transistor-based successor to the IBM 7000 series. Important engineers on the project included Fred Brooks and Gerry Blaauw . The project plan for the 8000 series was presented by Fred Brooks in January 1961.
The Citation X business jet is one such aircraft with a uni-directional PTU, protected by check-valves and a back-pressure stall line, designed to allow the right hand hydraulic system to assist the left hand hydraulic system and the left hand auxiliary motorpump to retract the landing gear during a port engine failure only.
