1. Application Description:

The double needle pressure gauge is mainly suitable for measuring the pressure in the hydraulic system or the storage cylinder on the locomotive and vehicle. It can also measure the two same or different pressures on the non-corrosive, non-crystallizing and non-solidifying media of copper alloy and tin-lead alloy fiber material.

2. Structure principle:

The instrument consists of two separate measuring systems and indicating devices. After the measured pressure acts on the two pressure measuring elements (spring tube), the tube end will produce corresponding displacement. After amplified by the transmission mechanism, the two measured pressure values will be indicated on the dial respectively by the red and black Pointers fixed on the gear shaft.
