Intelligent Digital Pressure Calibrator is a powerful portable professional intelligent pressure calibrator, which can measure pressure, current, voltage, temperature, switch, time and other items, and has DC24V power output function. It adopts a super-large FSTN segment code LCD display, and multiple measurement items can be measured and displayed at the same time; the gray background and white backlight have great visual impact. It integrates the common applications of the majority of users and provides users with a variety of additional functions, such as pressure leak detection, multiple triggers of pressure switches, pressure peak records, large-capacity data file storage, convenient serial port instructions, and pressure data storage. percentage display etc. It provides users with a convenient man-machine interface and a common navigation key design, which is in line with the use of modern international general electronic equipment.

TheYZQ-120HH Intelligent Pressure Calibrators with HART protocol, a single range, full scale pressure measurement, high accuracy DC current, voltage measurement and the 24VDC power output function instrument. Can be used to verify the ordinary (precision) pressure gauge, pressure transmitter, pressure regulating valves, pressure switches and pressure of real-time measurement, and can debug the HART smart pressure transmitter.

Main feature

The Digital Pressure Calibrator is a very good pressure measurement tool, which technically improves the performance of the pressure calibrator. In the measurement industry, the pressure calibrator is indispensable. The main performance characteristics of the pressure calibrator have

1. The casing of the pressure calibrator is all metal, which is firm and reliable, and can withstand strong impacts.

2. The pressure calibrator can be used to detect pressure, current, etc. at the same time, and it is very intuitive and clear, and it is very convenient to use. Not only that, the range of manual pressure generation using the pressure calibrator is relatively large, and can be used in different occasions.

3. The components of the pressure calibrator are very fine, and they are produced through special production, and their airtightness is very good, which meets the relevant standards.

4. There is a micro-regulator installed in the pressure calibrator. When it is used, it can realize the verified pressure, and the performance has been greatly improved. Not only that, but in the pressure calibrator there is also an on/off option, which is very simple to switch.

Technical principle

The Digital Pressure Calibrator is small in size, light in weight and easy to carry. It can be operated directly on the panel to adjust the full scale.

The intelligent pressure calibrator has a high-performance microprocessor to continuously correct the zero point and linearity of the meter to ensure that the zero point and accuracy of the meter have good repeatability and stability for a long time, and the measurement accuracy is high. With an over-range alarm function, when the applied pressure exceeds the rated full-scale + 2500 words, the instrument will display OVER RANGE! P and the built-in buzzer will sound intermittently to indicate that the pressure (current) exceeds the full range, the pressurization 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.
