Product introduction


YW-100B series precision Axial Digital Pressure Gauge is a high-precision intelligent pressure measuring instrument developed and produced by our company according to the latest national standards. YW-100B series digital pressure gauge is mainly composed of pressure sensor and signal processing circuit. Imported pressure sensor is used, with superior performance, high precision, corrosion resistance, shock resistance, vibration resistance, low temperature drift, high stability, etc. The signal processing circuit adopts the latest ultra-low power consumption processor, signal processing chip and power supply Management chip composition. Powered by a large-capacity high-performance lithium battery, no external power supply is required. The appearance of the instrument is exquisite, small and beautiful, and it is easy to use and operate.

·Pressure unit: mmH2O, mmHg, psi, kPa, MPa, Pa, mbar, bar up to ten pressure units (optional);

·It can display the dynamic change curve of online pressure measurement, peak recording function, etc. (optional);

· Various additional functions. Such as RS486 interface output, 4-20mA output, data instant messaging output USB interface, storage function.


Axial Digital Pressure Gauge is easy to install and is widely used in various water systems, chemical, petroleum and other industries. The casing of the pressure gauge is generally stainless steel, the surface material is glass, and the pressure gauge components include spring tubes and the like. Under the action of pressure and vacuum, the spring tube produces elastic deformation to cause the displacement of the tube end. The displacement is amplified by the mechanical transmission mechanism and transmitted to the indicating device, and then the pointer indicates the measured pressure or Vacuum value.
