Single 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.
