Below we have summarised some of the most common symbols you may come across. �� The dark upper triangle in these hydraulic symbols indicates fluid going out of the system and hence represents a pump. 3.9.2 Quick Disconnect 3.9.3 Without Checks 3.9.4 With Two Checks Page 4 of 24 CONNECTED DISCONNECTED. An electronic pressure switch operates according to the principle of strain gauges, which are switched in a full bridge. Because most units are very small, the displacement of the unit is factored into the measurement. Hydraulic Pressure Switch Valve. Devices that close or open electrical contacts in the event of pressure load (DIN ISO 1219-1). A pressure switch is an instrument that automatically senses a change in pressure and opens or closes an electrical switching element, when a predetermined pressure point is reached. They are generally used if an electrical switching command or status signal should be issued when a set (pre-selected) pressure value is reached and exceeded, to trigger an immediately following work cycle (actuation of an electromagnetic directional valve) or to end a cycle sequence (deactivation of the pump motor, neutral position of an electromagnetic directional valve). Piston switches can also be designed for high pressures, but due to the sealing friction they have a hysteresis . Controlling pressure is essential in all hydraulic systems. %PDF-1.4 %���� 0000041560 00000 n Figure 5-10 shows a pressure switch.

Below we have summarised some of the most common symbols you may come across. �� The dark upper triangle in these hydraulic symbols indicates fluid going out of the system and hence represents a pump. 3.9.2 Quick Disconnect 3.9.3 Without Checks 3.9.4 With Two Checks Page 4 of 24 CONNECTED DISCONNECTED. An electronic pressure switch operates according to the principle of strain gauges, which are switched in a full bridge. Because most units are very small, the displacement of the unit is factored into the measurement. Hydraulic Pressure Switch Valve. Devices that close or open electrical contacts in the event of pressure load (DIN ISO 1219-1). A pressure switch is an instrument that automatically senses a change in pressure and opens or closes an electrical switching element, when a predetermined pressure point is reached. They are generally used if an electrical switching command or status signal should be issued when a set (pre-selected) pressure value is reached and exceeded, to trigger an immediately following work cycle (actuation of an electromagnetic directional valve) or to end a cycle sequence (deactivation of the pump motor, neutral position of an electromagnetic directional valve). Piston switches can also be designed for high pressures, but due to the sealing friction they have a hysteresis . Controlling pressure is essential in all hydraulic systems. %PDF-1.4 %���� 0000041560 00000 n Figure 5-10 shows a pressure switch.

An electronic pressure switch operates according to the principle of strain gauges, which are switched in a full bridge. Because most units are very small, the displacement of the unit is factored into the measurement. Hydraulic Pressure Switch Valve. Devices that close or open electrical contacts in the event of pressure load (DIN ISO 1219-1). A pressure switch is an instrument that automatically senses a change in pressure and opens or closes an electrical switching element, when a predetermined pressure point is reached. They are generally used if an electrical switching command or status signal should be issued when a set (pre-selected) pressure value is reached and exceeded, to trigger an immediately following work cycle (actuation of an electromagnetic directional valve) or to end a cycle sequence (deactivation of the pump motor, neutral position of an electromagnetic directional valve). Piston switches can also be designed for high pressures, but due to the sealing friction they have a hysteresis . Controlling pressure is essential in all hydraulic systems. %PDF-1.4 %���� 0000041560 00000 n Figure 5-10 shows a pressure switch.
