The function of the pressure switch is to detect, display, alarm and control signal output, to ensure the normal operation of the system, through the high-speed MCU acquisition and processing data, built-in precision sensors for compensation, is the detection of pressure, liquid level signals, pressure, liquid level monitoring and control of high-precision equipment. Widely used in chemical industry, machinery, hydrology, electric power, environmental protection and other measurement of gas, liquid pressure in the automatic system. Because adjust convenient and agile, installation is simple, can replace the occasion that USES liquid level switch most.
Pressure switch is when the pressure in the system is higher or lower than the rated pressure, the safety of the sensor in the disc instantaneous movement, through the connecting rod to push switch connector on or off, when the pressure drop to or the raising of the rated value, the disc transient restoration, automatic reset switch, or simply, when the measured pressure exceeds rating, displacement of the free end of the elastic element, directly or after comparison switch element, change the on-off state switching element, achieve the goal of measured pressure control. The elastic elements used in the pressure switch are single-coil spring tube, diaphragm, diaphragm and bellows.
Purpose of pressure switch
1. G&L electronic pressure switch amplifies pressure signal through high-precision instrument amplifier, collects and processes data through high-speed MCU, and compensates with built-in precision sensor. It is a high-precision equipment for detecting pressure and liquid level signal, realizing pressure and liquid level monitoring and control.
2, widely used in chemical industry, machinery, hydrology, electricity, environmental protection and other measurement of gas, liquid pressure automation system. Because adjust convenient and agile, installation is simple, can replace the occasion that USES liquid level switch most.
3. The core of the product adopts new intelligent microprocessing chip with stable functional and practical performance.
4. LED display current pressure or liquid level value.
5. The pressure or liquid level can be set to start or stop according to your own needs.
6. Three units of four-led products can be selected according to customers' needs: Mpa, kg. F/CM2, PSI.
7. High and low pressure or liquid level alarm points can be set and output to the control equipment through relay or optical coupler; Output switch quantity of double - circuit relay (single pole double - throw).
8. High precision pressure sensor, higher precision than mechanical pressure switch, less hysteresis, fast response, stable and reliable; No dead zone adjustment, can be in the entire range of any set relay operating pressure point.
9, use the button to adjust the action pressure, easy to use, more flexible; Protection grade: IP65, can be used in harsh environment.
