Mechanical Pressure Switches Introduction pplications Mechanical pressure switches, also known as hydro-electric pressure monitors, are used to connect or disconnect electric circuits. pressure switch can serve as a control unit and as an optical or acoustic monitor or indicator. pressure switches are chiefly used in hydraulic systems for monitoring minimum pressures, such as protecting pumps from dry operation or as protection for oil lubrication systems. They can also be used for monitoring maximum pressures, such as automatic switch-off or warning device before a pressure relief valve reaches its limit pressure (fig. 1). nother application for pressure switches is the control of storage loading processes. fter the storage capacity is reached (Pmax) the flow is stopped and the pump shuts down. When the storage pressure drops below a defined minimum value (Pmin), the pump is automatically started again. The switch hysteresis (Pmax Pmin) can be freely selected with two pressure switches and one solenoid valve (fig. 2). Within certain pressure ranges the storage process can be controlled with only one pressure switch, the KD1 compact pressure switch which specifically designed for this application. The pressure set points Pmax and Pmin are factory set according to your requirements. Life Span and ccuracy The life span and accuracy of pressure switches depend on the frequency and peaks of pressure changes, the number of load cycles and temperature influences. For proportional operation pressure switches the highest accuracy is achieved above 70 %, the longest life span below 0 % of the performance range (fig. ). The best combination of life span and accuracy is, however, between 0% and 70% of the performance range. Contact Materials pressure switches have silver contact micro switches. On request we also supply micro switches with gold-plated contacts. Gold-plated are almost exclusively used on micro switches that are only exposed to low electrical loads. Fig. 4 depicts the standard values for the use of silver or goldplated contacts. We are happy to assist you in the selection of the material best suited for your application. Summary: The product of current and voltage should not exceed 0.12 V. Recommended values: current should range at < 400 m and voltage at < 0 V. If operated on alternating current the above values are peak values. Contact Protection The micro switches (MS) used in the pressure switches are normally suitable for both direct and alternating current operation. Inductive, capacitive and lamp loads may, however, considerably reduce the life span of a micro switch and, under extreme circumstances, even damage the contacts.

Pressure Mechanical Pressure Switches Introduction Capacitive Loads and Lamp Loads Capacitive and lamp loads may be accompanied by very high discharge rates or start-up current rushes 15 times higher than the rated value. Under such circumstances, current limiters (for instance a protective resistance) should be used (fig. 5 and 6). Inductive Loads High inductive peak loads during disconnection may considerably reduce the life span of a micro switch. The electric circuit can be protected by following the wiring diagram in figure 7 and 8. The ratings of the individual elements (diode, varistor etc.) are determined by the corresponding application. Pulsation and Vibrations within the System? How to remedy the problem: Pulsation and vibrations within the system can affect the function of the pressure switch. There are two different types of pressure switches: one type is sufficiently protected against pulsation and vibrations occurring during operation due to its solid design, the others are designed for precision adjustment which, consequently, makes them more sensitive to such influences. Please refer to the summary for compact pressure switch values regarding vibration resistance. To ensure proper functioning of the pressure switch, please observe the following recommendations: Mechanical Vibrations Use rubber buffers between units and wall for wall mounted units. Pulsation/Vibration of the Medium Use flexible hoses instead of pipes. If this is technically not possible, place "pulsation restrictors" in front of the pressure switch, for example: helical pipes commercial pulsation snubbers diaphragm accumulators s air pockets can enhance pulsation, please ensure that the hydraulic system is properly vented.
