Audited Supplier | The main characteristics of DUNGS pressure switch: 1. Adopting the British pipe thread quick connector or copper pipe welding installation structure, the installation is flexible and convenient to use, without the need for special installation and fixation. 2. The plug-in wire type connection can be freely selected by users 3. Sealed stainless steel sensor is safe and reliable. |
| Technical parameters: Range: -100Kpa~200MPa; Power supply voltage: 12-35V DC (24V DC calibration voltage)/AC 220V AC power supply output relay capacity: 380V 3A, 220V, 24V DC, etc. Accuracy: better than 0.05% FS, 1% FS, etc. Various settings range: The sampling rate can be set for the full range range range: 10 times/second (the speed can be customized according to customer needs). Interface threads: M20 * 1.5, G1/4, G1/2, 1/4NPT (customizable according to customer needs) DUNGS The working principle of a pressure switch: is that when the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch connector is pushed through the connecting guide rod to connect or disconnect. When the pressure drops to or rises to the rated recovery value, the disc resets instantaneously, and the switch automatically resets. In other words, when the measured pressure exceeds the rated value, the free end of the elastic element displacement occurs, Directly or after comparison, push the switch element to change its on/off state, achieving the purpose of controlling the measured pressure. The elastic components used in pressure switches include single coil spring tubes, diaphragms, diaphragm boxes, and corrugated tubes. |
| Operation method: 1. Method for setting control pressure: (1) Short press the ON/OFF button to turn off the running indicator light and turn off the pressure control system. (2) Set the control upper/lower limit by short pressing the SET key once to enter the lower limit setting state (corresponding to the lower limit indicator light on). By setting the value, after setting the lower limit, short press the SET key to enter the upper limit setting. The setting method is the same as above (3) After setting, press the SET key to automatically save the set values to the computer chip (after parameter modification, no key operation within 5 seconds will automatically save the current parameter settings). (4) Press the ON/OFF button again (corresponding to the running indicator light), and the motor will start working. 2. Unit switching method: Short press the ON/OFF button to turn off the running indicator light, and short press the increase button to switch units between MPa, Kg/cm, and PSI at will. After setting up, turn on the running indicator light. 3. Zero position reset function: Short press the (ON/OFF) run button to turn off the run indicator light, long press the decrease button for 5 seconds to reset the current pressure value and correct the zero position error. After setting up, turn on the running indicator light. (When using this function, the pressure switch must not apply pressure.) Press and hold the SET key for 3 seconds to enter the system settings, and then short press the SET key to display the following function modes in sequence. After setting all function modes, press the (ON/OFF) run button to automatically store the set values into the computer chip(For reference only) |
