As a comprehensive further development with additional functions, the model PSD-4 electronic pressure switch is also notable. The successful design as well as the excellent functionality of the WIKA pressure switches were already confirmed by winning the “iF product design award 2009” for the model PSD-30. Learn even more about electronic pressure switches in the WIKA blog post " What is an electronic pressure switch?". Switch points, output signal, delay time, hysteresis and many other parameters can be individually adjusted to suit the application. ![]() Electronic pressure switches often feature a display from which the measured value of the pressure can be read, while flexible settings and programming are also possible. Thus, not only is it identified whether the defined switch point has been reached, but the actual measured pressure is transmitted. Along with the electrical switching signal, many electronic pressure switches offer an additional analogue signal proportional to the pressure. What is an electronic pressure switch?Īn electronic pressure switch is based on an electronic pressure sensor. The Ex d-approved switches are available in epoxy-resin-coated cases made from copper-free aluminium. When does one use a WIKA explosion-protected mechanical pressure switch?įor operation in hazardous areas of process engineering, WIKA mechanical pressure switches are available in Ex ia or Ex d versions. Electronic pressure switches are also very well suited for low-power switching. Even the switching of electrical loads up to 15 A/220 V is possible without problems with a mechanical pressure switch from WIKA.įor the switching of very low voltages, such as those used in PLCs, WIKA offers argon-gas-filled microswitches with gold-plated contacts. Adjustable limit switch is accessible from the front of the gage and the contacts have a self-cleaning motion to enhance electrical continuity. They feature high long-term stability and precision. WIKA pressure switches are fitted with high-quality microswitches. The resulting reliability is one of the advantages of mechanical pressure switches.

If, with a mechanical pressure switch, the defined pressure is reached and the switch is actuated, the switch will send an electrical signal. Laboratory analysis of SF 6 & alternative gases.Basic materials (minerals, metals, paper).Valves with integrated pressure regulators.Heat transfer and distribution stations.Laboratory analysis of SF6 and alternative gases.International service network with system calibration.Power transmission and distribution (SF 6).Precision pressure measuring instruments.Pointer: High visibility with a pointer calibration hub. Geared Movement: 302 and 304 stainless steel. Gage Accuracy: 2-1-2 ☒% for the first and last quarters of the scale, the middle half is ☑%. (114 mm) white on black, dual scaled psi /kPa OPLBP – SPDT dry relay contacts 10A, 125 VACĭial: 4-1/2 in. OPLC and OPLFC – 1 SPDT Center off 2A, 30 VDC / 1A, 125 VAC pilot duty More information is available on the manufacturer website. OPLC-S-2000: 4. ![]() ![]() Murphy OPL pressure gauges are part of the Murphy engine protection and monitoring range. ![]() Contact lead termination is by pigtail wires. This version can be environmentally sealed with either the ES or OS options. The OPLFC is typically used in control panels for compressors, pumps, etc. The lockout must be done externally through the control circuit. It has all of the features of the OPLC except the low limit contact lockout. The OPLFC is a panel mounting version of the OPLC. Used in conjunction with AT03069 Throttle Controller Suitable for engines or electric motors with appropriate Murphy magnetic switch or transformer relay assembly. An SPST toggle switch is provided to override the low limit contact for equipment start-up. Pointer closure against either of the adjustable contacts completes the pilot-duty circuit. Adjustable high and low limit, ungrounded contacts are used to operate alarm, shutdown or start-stop circuits. The OPLC is a surface mount, indicating pressure gauge and switch. Murphy OPL pressure gauges for engine protection in the event of out of tolerance pressure.
