The HZQD-510 intelligent SF6 gas density relay calibrator is an intelligent SF6 density relay calibration instrument. The calibrator adopts high precision pressure sensor and the high speed A/D converter, combined with 32-bit high performance microprocessor which can check the performance of a variety of SF6 density relay, can accurately measure pressure value when the signal move under the current temperature, automatically complete the standard pressure conversion of any environmental temperature at 20 ºC, and can immediately print, storage test data for reference, at the same time automatic identification test failure in the process, it is easy to carry, simple operation, high test precision, strong stability, good reliability.
1.Density relay calibrator using 32-bit microprocessor and the high-speed signal processing chip for detection and control, high degree of integration, electromechanical integration design, high precision, good repeatability, high reliability.
2.Large LCD screen and rotate the mouse (a key shuttle) man-machine interface, the operation is simple, beautiful interface, parameters and condition are clear at a glance.
3.Automatic complete pressure measurement and 20 ºC value conversion, thus completed the pressure and temperature of dynamic self-compensation, and display pressure under measured environmental temperature and environmental temperature at 20 ºC. Completely solve the difficult of SF6 calibration on-site. Automatically complete all the test by instrument without human intervention, to avoid the tedious manual pneumatic regulating operation;
4.Print test results, and intelligent analysis for test results.
5.Can store 50 times test results, and can keep data when power off, can query and print previous test results at any time.
6.No need constant room during the process of calibration, can calibrate SF6 gas density relay and pressure gage within any valid temperature range.
7.Equipped with a variety of models of transition joints, the density of most types of switch relay don't have to disassembly and can directly calibration on-site.
8.Very little gas consumption during calibration, no waste of SF6 gas, test cost is low, no environment pollution.
9.With functions of on-line modification of the system clock, with functions of on-line modification system pressure, can correct on site, the core components are imported components, with reliable performance.
10.can test a set of alarm signal, two groups blocking signal at the same time.
11.It is portable instrument, convenient and reliable, it is the best choice of SF6 relay calibration.
