Functional characteristics

1 Wide test range, advanced structure principle

Domestic gas relay (baffle type) and imported gas relay (double float structure) can be measured. Advanced pipeline design and theoretical optimization, high-precision 24-bit digital sensor, advanced data acquisition card and fieldbus, the latest ARM control technology and analysis strategy, to achieve breakthrough high-precision measurement

2 kinds of flange change head

Special design, easy to replace, stable measurement, can be a variety of specifications (Φ25, Φ50, Φ80) gas relay for high-precision and stable measurement, suitable for domestic and foreign gas relay calibration of various types, can realize the gas relay sealing performance test, heavy gas protection action flow rate value and light gas protection action gas volume value detection and verification.

3 Volume Measurement

Through the clever volume cylinder design and specially designed pressure sensor, as well as the precise algorithm, the volume is measured accurately in real time. The measurement resolution reached 0.1 ml

4 Flow Rate measurement

The flow rate is automatically increased by microcomputer control to ensure the stability of the flow rate increment and avoid the unreliability of the results caused by the flow rate fluctuation. The three independent channels and the test pipeline are the same caliber as the relay. The specially designed flow velocity acquisition system accurately completes the flow velocity measurement of various specifications of gas relays, and the measurement resolution reaches 0.01 m/s. With reverse oil flow impact test function,

5 Sealing Measurement

Through reasonable pipeline design and layout, the air compressor is used to simulate gas internal pressure to test the sealing performance of the relay. One-click operation of sealing test, intelligent judgment of test results, through the combination of manual interruption and intelligent detection interruption, reliable interruption of operation before the occurrence of danger, to ensure the safety of operation

6 Stable device performance

Using cluster bus layout, reasonable data acquisition, control line layout, has a good electromagnetic compatibility and anti-interference performance, to ensure the stable operation of the equipment in harsh environment

7 Easy to fix

Using hydraulic transmission pressing mechanism, easy to align and tighten, easy to operate, easy to accurately install the gas relay, with a good sealing gasket, to avoid the phenomenon of oil injection during the test process, to ensure high precision measurement and good repeatability.

8 Large area transparent protective cover

With transparent visual protection device, you can view the entire measurement environment and intuitively judge the relay performance. Strong structure to ensure safe operation

9 With oil heating protection measures

Multi-heavy oil heating protection measures prevent harmful substances from being generated during the heating of insulating oil, which may harm the operator and the environment. At the same time, the low liquid level protection function of insulating oil prevents unstable flow rate caused by low liquid level and inaccurate calibration data

10 Independent inspection ports

The device has an independent calibration and quality inspection interface, and independent calibration and quality inspection interface, which can be used by a third party without disassembling the entire system.

11 large color screen display, beautiful interface

windows operating system, 19 inch super large screen color LCD, industrial mouse and keyboard, network communication, all Chinese color graphical operation interface and real-time help system, intuitive and simple operation, can realize the automatic test of all projects, and can view, analyze, store and print the results

Selection of gas relays

First understand the necessary conditions:

① The power supply voltage of the control circuit can provide the maximum current;

② Voltage and current in the controlled circuit; ③ The controlled circuit needs several groups and what form of contacts.

When the relay is selected, the power supply voltage of the general control circuit can be used as the basis for selection. The control circuit should be able to provide sufficient working current to the relay, otherwise the relay suction is unstable. After consulting the relevant information to determine the conditions of use, you can find the relevant information to find the type and specification number of the relay you need. If you have a relay on hand, check whether it can be used according to the data. Finally consider whether the size is suitable.

Pay attention to the volume of the appliance. If it is used for general electrical appliances, in addition to considering the chassis volume, small relays mainly consider the circuit board installation layout. For small electrical appliances, such as toys and remote control devices, ultra-small relay products should be selected.
