ZN-YBS-WY type vacuumPressure calibratorIt is a new type of testing instrument produced and developed by Jiangsu Zhongneng Instrument Technology Co., Ltd. Its performance price ratio is superior to similar products from Druck in the UK, including vacuum testingPressure calibratorNot only does it solve the calibration of standard pressure, but it also better meets the comprehensive testing needs on site.
ZN-YBS-WY type vacuumPressure calibratorThe basic accuracy is divided into two types: 0.1% and 0.05%. It is an ideal high-end tool gauge for laboratories, factories, and colleges, and can be used as a standard gauge for medium precision pressure testing. It is an ideal calibration instrument for pressure gauges, pressure gauges, pressure transmitters, pressure switches, vacuum gauges, and other pressure instruments.
● Characteristics
1. ZN-YBS-WY type vacuumPressure calibratorIt is a portable instrument that can be used for both AC and DC. It can measure pressure and current, and display them on an LCD screen. It also has a 24VDC output. In addition, the front panel of the vacuum pressure calibrator is equipped with a pressure pump, making it an ideal on-site calibration instrument.
2. High performance microprocessors continuously correct the zero and linearity of instruments, ensuring good repeatability and stability of zero and accuracy over a long period of time, and high measurement accuracy.
3. The calibrator has an over range alarm function. When the applied pressure exceeds the rated full range+2500 words, the instrument will display OVER RANGE! P and the built-in buzzer will intermittently sound to indicate that the pressure (current) exceeds the full range. The pressurization should be stopped and some of the pressure should be removed to keep it within the specified range to avoid damaging the pressure sensor.
4. When the current measured by the calibrator exceeds 22mA, the instrument will display OVER RANGE! And the built-in buzzer will intermittently sound to indicate that the measured current exceeds the range.
5. The software content of the calibrator is rich, and the operation is simple and clear.
6. Adopting a thin film panel and imported light touch opening, the style is novel and the button life is long.
7. LCD backlight, pressure and current display, intuitive, clear, compact and reasonable structure. The pressure calibrator is small in size, light in weight, and easy to carry.
8. Install a manual pressure generator on the front panel of the calibrator, with a pressure range of -90KPa to 1.6MPa, and equipped with fine adjustment and release valves. The manual vacuum rate reaches 95%, which is at the world's advanced level. The pressure source components have been finely ground and have good air tightness, meeting the IP54 sealing standard.
9. It can be directly operated on the panel to calibrate the full range.
10. Metal shell, strong anti-interference ability, firm and stamping resistant.
11. Volumetric fine-tuning makes it easy to achieve calibration point pressure.
