Pointer differential pressure gauge
It is suitable for air micro-pressure measurement, and it is widely used in the detection and display of environmental micro-pressure in the pharmaceutical and microelectronics industries. The differential pressure gauge can be embedded or suspended on the outside of the wall of the clean room, without power supply, with high sensitivity and high measurement accuracy. It is an ultra-low range, inexpensive, robust field indicator that utilizes the frictionless Magnehelic motion principle to eliminate wear, hysteresis and backlash. No liquid filling, no vaporization and freezing, can quickly indicate the pressure of low-pressure, non-corrosive gas (positive pressure, negative pressure (vacuum) and differential pressure). The pointer differential pressure gauge is designed to resist shock, shock and overload. There will be no problems such as evaporation and freezing of the pressure gauge liquid, and no poisoning or errors will occur. It has been confirmed by Shanghai Metrology and Testing Technology Research Institute of East China Metrology and Testing Center that in the same measurement environment, the main parameters of the pointer differential pressure gauge surpass those of similar products in the United States, and it is currently the smallest differential pressure gauge in the world.
