The EM2000M digital differential pressure gauge is designed for measuring differential pressure, positive pressure, and negative pressure in air and gas systems. It is widely used in HVAC systems, cleanrooms, air filtration systems, dust collection systems, fan and blower monitoring, industrial ventilation systems, laboratory pressure monitoring, and building automation systems. It is suitable for real-time pressure monitoring and industrial control applications.

Main features include digital display with real-time pressure reading, multi-unit switching (Pa/kPa/mbar etc.), dual analog + electronic output capability, high accuracy measurement, stable long-term performance, compact industrial design, low differential pressure measurement capability, alarm/control output function (model dependent), and easy installation and operation. It is designed for monitoring and automation control systems.

The EM2000M measures pressure difference between two air/gas ports using an internal sensing system. Pressure enters the high and low ports, the sensor detects the pressure difference, converts it into an electrical signal, and displays the real-time value on the screen. Output signals can be transmitted to PLC or control systems for automation.

The EM2000M is mainly used for clean, dry, non-corrosive gases such as air, HVAC airflow systems, ventilation ducts, and non-corrosive industrial gases. It is not suitable for liquids, strong corrosive gases, or high humidity condensation environments unless specially protected.

Yes. The EM2000M is a powered digital instrument and requires a DC power supply to operate. It uses electrical power for display, sensing, and output functions and cannot operate without power.

Yes. Depending on configuration, the EM2000M can provide alarm output, signal transmission to PLC systems, and pressure-based automation control functions. It is suitable for intelligent industrial monitoring systems.

The EM2000M uses a digital LCD display that shows real-time pressure values clearly. It supports fast response, multi-unit switching, and stable visibility in industrial environments. Some models may include backlight.

Typical specifications include differential pressure measurement, digital LCD display, low pressure range options, industrial-grade accuracy, DC power supply, air/gas compatibility, and panel or pipeline installation depending on model configuration.

Yes. It is widely used in HVAC systems for filter monitoring, airflow balancing, fan pressure control, duct pressure measurement, and cleanroom pressure control. It improves system efficiency and maintenance accuracy.

Compared with mechanical gauges, EM2000M offers digital real-time display, higher automation capability, alarm and control output functions, better PLC integration, and more flexible measurement options. It is more suitable for smart industrial systems.

Yes. The EM2000M is designed for industrial applications and offers stable operation, anti-interference capability, long service life, and continuous monitoring performance. It is widely used in factories, laboratories, HVAC systems, and automation systems.

Before purchasing, buyers should confirm pressure range, output type, power supply specification, connection size, installation method, working environment, medium type, and OEM customization requirements to ensure proper system compatibility.
