Memory type double needle pressure gauge

  The double needle pressure gauge consists of two independent measurement systems and indicator devices. The working principle is based on the elastic deformation of the elastic element (spring tube in the measurement system). Under the pressure of the measured medium, the ends of the two spring tubes are driven to produce corresponding displacements, which are amplified by the transmission of the rod through the gear transmission mechanism. The red and black pointers on the fixed gear shaft indicate the respective degrees of rotation of the two measured values. The double needle pressure gauge is equipped with a stainless steel casing, which is sturdy and aesthetically pleasing, and has rust and waterproof functions. Adopting safety glass, high-definition printed dial, clear and distinct scale, convenient and easy reading, shock resistant model can be filled with glycerin or silicone oil. Double needle pressure gauges are widely used in mining industry, gas pipelines, household…
