Overview
Overview: With the development of the domestic metrology industry, the original gas medium oil lubricated vacuum piston pressure has gradually withdrawn from the historical stage and been replaced by gas piston pressure gauges. Pure gas piston pressure gauges have stable and reliable pressure, greatly improving the sensitivity and uncertainty of piston pressure gauges and providing a perfect standard instrument for high-precision metrology
Product Details
summary:
With the development of the domestic metrology industry, the original gas medium oil lubricated vacuum piston pressure has gradually withdrawn from the historical stage and been replaced by gas piston pressure gauges. Pure gas piston pressure gauges have stable and reliable pressure, greatly improving the sensitivity and uncertainty of piston pressure gauges and providing a perfect standard instrument for high-precision metrology.
Purpose:
Gas piston pressure gauge is a high-precision pressure standard that uses gas as the working medium to measure and calibrate gauge pressure, absolute pressure, vacuum pressure (negative pressure), etc. The piston pressure gauge system is made of tungsten carbide material. This ensures that the piston has the characteristics of rust resistance, wear resistance, and long service life. Compared with piston pressure gauges that use liquid as the working medium, gas piston pressure gauges have longer self rotation duration, higher sensitivity, better repeatability, and accurate and reliable measurement data due to the different working media they use.
FKQ type piston pressure gauge meets the following requirements:
Compliant with JJG1086-2013 Gas Piston Pressure Gauge
Complies with JJG59-2006 "Weights"
Complies with JB/T-12017-2014Gas piston pressure gauge
Patent certificate for piston pressure gauge:
The use of a dynamic sealing structure
Features:
The piston system is made of tungsten carbide material, which is wear-resistant, has a low temperature drift coefficient, and has a long service life.
2. Choose from a pressure range of -100KPa to 600KPa
3. Meet the requirements of JJG1086-2013 "Verification Regulations for Gas Piston Pressure Gauge" to distinguish it from traditional oil lubricated gas piston pressure gauges.
4. The pressure interface is a quick interface, which is convenient and fast.
5. The valve adopts a unique design, making pressure regulation convenient.
6. Optional temperature, pressure, and drop digital indicator system, convenient and fast.
7. Positive and negative voltage switching, convenient and fast.
8. Measurement range: The nominal measurement range is consistent with the actual measurement range.
9. The piston system can be easily taken out for inspection (without carrying a heavy mainframe)
10. Can be used as a calibration piston pressure gauge for transmission purposes; It can also be used for high-precision testing. Can be equipped with kg weight and MPa weight.
11. Advanced pressurization system, lightweight and durable!
12. The weight adopts a hanging basket structure, with a low center of gravity and excellent stability.
13. Each unit is issued a "Verification Certificate" by the Northwest Institute of Metrology and Testing
