PSMDC density relay calibrator is an intelligent automatic SF6 density relay calibration instrument. This instrument adopts microcomputer technology, which can check various SF6 density relays, and a portable calibration instrument that standardizes the pressure of SF6 gas at any ambient temperature, and also produces, safely runs, and pre-conditions SF6 electrical products. Trial and maintenance provide convenience. In a closed vessel, the SF6 gas pressure at a certain temperature may represent the density of SF6 gas. In order to be unified, it is customary to use the SF6 gas pressure at 20°C as a scale value. In the on-site calibration, under different ambient temperatures, the measured pressure value shall be converted into its corresponding pressure value at 20°C to judge the performance of the SF6 density relay. The PSMDC density relay calibrator is automated for this process and is accurate, flexible and convenient. In addition to checking the SF6 density relay, the instrument also has the functions of checking the pressure gauge and density meter and self-calibration of the instrument. This not only can be used in one machine, but also eliminates the problems of instrument inspection and return to factory calibration. . 
PSMDC density meter relay efficacy main functions and features <br> <br> this calibrator with high-speed single-chip measurement and control system as the core, high degree of automation, repeatability and high reliability.
The instrument can test both relative and absolute pressure relays.
The instrument adopts imported color large-screen LCD, user-friendly interface operation is simple and convenient (8-inch 800*600 true color screen).
The instrument verifies the SF6 density relay at the automatic acquisition temperature.
The instrument has a data storage function (which can store 40 sets of data) and has a power-down data protection function to facilitate the query of measurement data later.
The instrument can upload test data to the PC through the USB interface and automatically generate a dedicated test data table.
The instrument can check the normal temperature pressure gauge and density meter and print the test results.
All the equipment pipelines use quick connectors for easy connection.
The internal clock function of the instrument can also be used to modify the clock online.
The instrument has a check function to ensure the check accuracy of the instrument.
The instrument uses high-precision pressure sensors and world-leading pressure control elements.
The instrument is equipped with a variety of switch filter connectors, easy to operate and use.
The instrument has relay contact live test (requires no secondary power supply 220V when signal is collected) and no live test function. DC24V power supply is provided internally when the contact is not energized. When DC24V is selected, it can ensure that the signal is reliable under the condition of oil film. collection.
