The pressure calibrator is used to calibrate various pressure transmitters, pressure sensors, pressure switches, differential pressure transmitters, digital pressure gauges and special pressure calibrators. When measuring pressure, the measured pressure is displayed on the same screen as the set pressure percentage and the measured current. The current and current percentage can be selected through the display menu.

IntelligentPressure calibratorIt not only solves the calibration of standard pressure, but also better meets the needs of field comprehensive testing. For the convenience of customers, many manufacturers miniaturize and intelligentize the whole instrument, so that the pressure calibrator has multi-range and recording functions.

The pressure calibrator can be used to calibrate pressure switches, pressure gauges, ordinary pressure gauges, pressure (differential pressure) transmitters, pressure sensors and other pressure instruments.

Including instruments, image processing systems, verification software, computers and printers.

　　Pressure calibratorThe numerical control pressure source is used to automatically pressurize, the standard pressure value is obtained by the high-precision digital pressure sensor, the pressure gauge reading is recognized by the computer camera processing system, various error values are calculated, and the verification conclusion is made according to the corresponding verification regulations of the pressure instrument.

After receiving the "start verification" command, the computer sends a verification command to the numerical control pressure source. The numerical control system controls the system pressure to reach the required pressure point, and then transmits the standard pressure value to the computer. The computer shoots and identifies the reading of the pressure gauge through the image processing system, and then the electric control tapping head simulates manual tapping of the measured instrument (according to the requirements of the regulations), and then identifies the reading of the instrument. The identification results are compared with the standard pressure value of the high-precision pressure sensor, and various indication errors of the pressure gauge are obtained.

For pressure transmitters and pressure sensors, intelligent pressure calibrators measure their output electrical signals. After the pressure of the calibrator control system reaches the required pressure point, the software reads the electrical signal value of the pressure transmitter or pressure sensor and compares the value with the standard electrical signal value to calculate the error. After the verification is completed, calculate and store the error data, then display and print the error data table and verification results.Pressure calibratorThe internal high-performance microprocessor continuously corrects the zero point and linearity of the instrument to ensure that the zero point and accuracy of the instrument have good repeatability and stability for a long time, and the measurement accuracy is high. At the same time with overrange alarm function. When the pressure applied exceeds the rated full-scale 2500 words, the instrument will display over-range! P built-in buzzer will sound intermittently, indicating that the pressure (current) exceeds the full scale, the pressure should be stopped, and part of the pressure should be removed to make it within the specified range, so as not to damage the pressure sensor. When the current measured by the pressure calibrator exceeds 22mA, the meter will display overrange! And the built-in buzzer will sound intermittently to indicate that the measured current is out of range. The pressure calibrator is a pressure calibrator used to calibrate various pressure transmitters, pressure sensors, pressure switches, etc. It can measure current and pressure. The measured pressure is displayed on the same screen as the set pressure percentage and the measured current, and the current and current percentage can be selected through the display menu. For the convenience of customers, many manufacturers miniaturize and intelligentize the whole instrument, so that the pressure calibrator has multi-range and recording functions.

　　Pressure calibratorIt is an AC/DC portable instrument that can measure current and pressure, and display on the LCD at the same time, and output 24VDC. Part of the instrument is equipped with a hand pump, can be used in a certain range, is the ideal field calibration instrument.
