Yunyi Wholesale RS485 High Precision Rechargeable Calibration Standard Digital Pressure Gauge
Description
High-precision digital pressure gauge is a pressure measuring instrument that uses electronic sensors and digital display technology. It has the characteristics of high precision, intelligence, and multi-function. It is widely used in industry, laboratories, medical and other fields.
1. Main features of high-precision digital pressure gauges
High-precision measurement
The accuracy can usually reach ±0.1% FS (full scale) or higher, which is much higher than traditional mechanical pressure gauges (±1%~2.5% FS).
Adopt advanced sensors such as silicon piezoresistors, capacitive or ceramic piezoresistors, with good stability and strong anti-interference ability.
Digital display
The liquid crystal (LCD) or LED display directly displays the pressure value, and the reading is clear and intuitive, avoiding the parallax problem of mechanical gauges.
Supports multi-unit switching (such as MPa, psi, bar, kPa, etc.) to meet the needs of different scenarios.
Multi-function integration
Additional functions: peak recording, data storage, temperature compensation, wireless transmission (Bluetooth/Wi-Fi), etc.
Some models support 4-20mA, RS485 and other signal outputs, which are convenient for integration into automatic control systems.
Environmental adaptability
Vibration-resistant and shock-resistant, suitable for dynamic pressure measurement (mechanical gauges are easily damaged or have inaccurate readings in a vibrating environment).
It can work in a wide temperature range (-20℃~70℃), and the protection level of some industrial-grade products reaches IP65 or above.
