ASK OPG-DT-R1/4-39 đồng hồ đo áp suất khí kèm glycerin( 1Mpa ~ 40 Mpa)

Safety mark provided as the standard 270-degree pressure angle indications for improved clarity. This gauge can be mounted directly onto the pressure port of the modular type hydraulic circuit. he pressure gauge root section is equipped with special slots for absorbing pulsating pressure and surge pressure. Even of modular valves are stacked, pressure gauges do not make contact with each other. Movement of the pointer due to mechanical vibration is absorbed by the viscous drag by pure glycerin liquid in the hermetically-sealed pressure gauge. Movement of the Bourdon tube is also absorbed, improving the absorption effect of the pulsating pressure of the fluid. The pure glycerin liquid serves as lubricating oil for the friction part of the bearing and gear in the pressure gauge, thereby further improving the durability of the internal mechanism in comparison with the existing products. Safety measures are provided to ensure that the transparent sheet at the front is not shattered, and hydraulic oil is purged from the safety valve in the case that the Bourdon tube is broken. The green safety mark attached to the circumference of the transparent sheet assists in the setting of a pressure range and values. Select a pressure gauge whose top pressure reading is more than double the applicable pressure range.

Specifications

It screws directly into the modular valve pressure sensing port of the hydraulic circuit. A dedicated throttle for absorbing pulsating pressure and surge pressure is built into the pressure gauge stock. Pressure gauges do not touch each other even when modular valves are stacked. The viscous resistance of 100% glycerin liquid in a fully sealed pressure gauge provides better damping of needle movement due to mechanical vibrations. In addition, the movement of the Bourdon tube is damped, and the pulsating pressure absorption effect of the fluid is improved compared to conventional products. 100% glycerin liquid lubricates wear parts such as bearings and gears inside the pressure gauge and improves the durability of the internal mechanism. It also prevents corrosion of internal parts. Safety measures are taken so that even if the Bourdon tube breaks, the transparent plate on the front will not scatter and the hydraulic oil will escape from the safety cap. A green safety mark is attached to the periphery of the transparent plate, making it easy to set the pressure range and set value. As a selection criterion, select a pressure gauge with a maximum scale that is at least twice the pressure range you are using.
