Product Description:
1. Usage description:
Double needle pressure gauges are mainly suitable for measuring the pressure inside hydraulic systems or reservoirs on locomotives and vehicles. They can also simultaneously measure two identical or different pressures on copper alloys and tin lead alloy fibers that are non corrosive, non crystalline, and non solidifying media.
2. Structural principle:
The instrument consists of two sets of measuring systems and indicator devices, each with its own d. u. 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.
3. Main technical indicators:
