Description

1. Purpose Description:

Double needle pressure gauges are mainly used for measuring the pressure in hydraulic system or cylinder of locomotive and rolling stock. They can also measure the same or different pressure in non-corrosive, non-crystallized and non-solidified media of copper alloy and tin-lead alloy fiber.


2. Structure principle:

The instrument consists of two separate measuring systems and indicating devices. The measured pressure is applied to the two load measuring elements (spring tube), resulting in corresponding displacement of the tube ends respectively. After amplification by the transmission mechanism, the two measured pressure values are indicated on the dial respectively by the red and black Pointers fixed on the gear shaft.


3. Main technical indicators:

○ Degree: 1.6

○ Scale range: 0~1000; 1200; 1600; 2500kpa

○ Operating environment: 5~60℃, relative humidity not more than 80%

Temperature effect: no more than 0.4%/10℃(temperature deviation from 20±5℃)

○ Weight: 0.7kg
