YTS-80Z Double Needle Pressure Gauge (for subway)
The double needle pressure instrument is mainly used for measuring the pressure of locomotive air compressor, hydraulic system or cylinder. The measuring principle is mainly to use the spring tube to produce deformation under the action of medium pressure, and drive the pointer to deflect on the instrument index plate by driving the amplifier mechanism, indicating the measured pressure value.
The pressure gauge has an axial structure and measures two identical or different pressures simultaneously. Its interior is illuminated by the LED ring light source on the upper part of the dial, which is soft and easy to observe at night.
