Pressure Gauge Of The Gas Source
- Jun 30, 2017 -

Pressure Gauge A gas piston type pressure gauge is a measuring instrument that utilizes a hydrostatic equilibrium (ie, a fluid pressure acting on the effective area of the piston to balance the gravity of the load). Generally by the piston system, special weight, Pressure Gauge pressure checker composition, Pressure Gauge in addition to the need to equip the corresponding gas source.

BNHSQ series gas piston pressure gauge is a high accuracy pressure standard, with gas to do the working medium, can measure and calibrate gauge pressure, absolute pressure, Pressure Gauge vacuum pressure (negative pressure) and so on. Piston rod, piston cylinder material is tungsten carbide, with stainless steel, wear and long service life characteristics. Gas piston piston pressure gauge with working medium compared with the use of liquid to do the working medium piston pressure gauge compared to the gas piston pressure gauge piston rotation long duration, Pressure Gauge high sensitivity, good repeatability, accurate and reliable measurement data.

● meet the JJG1086-2013 "gas piston pressure gauge verification procedures" and JJG99-2006 "weight verification procedures."

● Piston rod and piston cylinder with high strength, high hardness, Pressure Gauge low expansion coefficient of tungsten carbide material, improve the piston system wear resistance, reducing the expansion coefficient and deformation coefficient.

● The weight is made of non-magnetic metal material and has been modified by the pressure deformation coefficient and the local gravity acceleration.

● Optional KG weight and MPa weight, used as a pass test piston pressure gauge, can also be used as a test digital pressure gauge, precision pressure gauge, pressure transmitter, Pressure Gauge pressure sensor and high precision test and other purposes.

● loading weight with basket structure, low center of gravity, good stability.

● The nominal range is the same as the measuring range. Other special measuring range can be customized according to the user's requirement.

● Piston working position using high-precision sensor, LCD display, high sensitivity, eye-catching intuitive.

● Working medium is high purity nitrogen, and equipped with positive and negative pressure switching valve, which can simultaneously access vacuum pump and nitrogen cylinder.

● using two M20 X1.5 quick pressure connector, Pressure Gauge which can be verified at the same time two check table, easy and easy disassembly.

● aluminum box, solid light, nice appearance, Pressure Gauge easy handling.

● Each certificate may be issued by the national statutory metrological verification institution.
