The LD-YBS-WY pressure transmitter calibrator is a portable instrument that can be used for both AC and DC. It can measure pressure and current, and display them on the LCD screen. It also has a 24VDC output. It is an ideal standard calibration instrument for calibrating and verifying pressure transmitters, general pressure gauges, and pressure switches.
One product overview
The LD-YBS-WY pressure transmitter calibrator is a new type of testing instrument produced and developed by our company. Its performance price ratio is superior to similar products from Druck in the UK. The pressure transmitter calibrator not only solves the calibration of standard pressure, but also better meets the needs of on-site comprehensive testing The basic accuracy is divided into two types: 0.1% and 0.05%. It is an ideal tool table for laboratories, factories, and colleges, and can be used as a standard table for medium precision pressure testing
II major function
The LD-YBS-WY pressure transmitter calibrator panel is equipped with a pressure pump, which is an ideal on-site calibration instrument.
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.
Using high-performance CPU and temperature sensor to automatically compensate for instrument temperature drift, ensuring a wide range of operating temperatures with high accuracy.
Low power consumption. After the battery is fully charged, it ensures a long continuous working time with high accuracy.
◆ Constant current charging, with automatic shutdown and protection functions for overcharging and undervoltage of battery voltage, ensuring that the battery is not damaged due to overcharging or undervoltage and has a long service life.
The low-power automatic undervoltage protection function ensures that the instrument will not damage the battery due to undervoltage even if the operator continuously turns it on for too long due to reasons.
The instrument has rich range functions and can be used for multiple purposes. It has multiple display styles and can simultaneously display pressure current, pressure water column, or pressure kgf/cm2 current percentage.
The instrument has an over range alarm function. When the applied pressure exceeds the rated full range by 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.
When the current measured by the instrument 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.
The software has rich content, simple and clear operation.
◆ Adopting a thin film panel and imported light touch opening, the style is novel and the button life is long.
LCD backlight pressure, current display, intuitive, clear, compact and reasonable structure. Small size, light weight, and easy to carry.
Install a manual pressure generator on the front panel, with a pressure range of -90KPa to 2.5MPa, 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.
◆ It can be directly operated on the panel to calibrate the full range.
◆ Metal shell, strong anti-interference ability, firm and impact resistant.
◆ Volumetric fine-tuning makes it easier to achieve calibration point pressure
