Usage description:
The YZS-102 dual needle pressure gauge is mainly suitable for measuring the pressure inside hydraulic systems or reservoirs on locomotives and vehicles. It can also simultaneously measure two identical or different pressures on copper alloys and tin lead alloy fibers that are non corrosive, amorphous, and non solidifying media.  

Structural principle:
The instrument consists of two independent measurement systems and indicator devices. The measured pressure acts on two pressure measuring elements (spring tubes), causing corresponding displacements at the tube ends. After amplification by the transmission mechanism, the red and black pointers fixed on the gear shaft indicate the two measured pressure values on the dial.  

Main technical indicators:

Accuracy level: 1.6
Scale range: 0~1000; 1200; 1600; 2500kpa
Environmental conditions for use: 5~60 ℃, relative humidity not exceeding 80%
Temperature impact: not greater than 0.4%/10 ℃ (with a temperature deviation of 20 ± 5 ℃)
Weight: 0.7kg
