Multi Unit Display Alarm Digital Pressure Transmitter , Intelligent Pressure Transmitter

Digital pressure transmitter, as the name suggests, is based on traditional analog or intelligent pressure transmitters and adds a digital display screen.

1. Local Visualization, Revolutionary Improvement in Debugging and Maintenance Efficiency
   • No additional tools required: On-site personnel can directly read the current pressure value without carrying a hand controller or multimeter, quickly determining if the equipment is functioning properly.
   • Real-time monitoring: Pressure fluctuations can be observed directly at the equipment site.
   • Simplified debugging: Intuitive menus and feedback are provided on the screen during parameter settings (such as range, unit, damping).
2. High Integration, Reducing Installation Points and Costs
   • Eliminates the need for a separate on-site pressure gauge, saving installation brackets, valves, and pipe openings.
   • Reduces potential leakage points, enhancing system reliability.
3. Powerful and Intelligent
   • Multiple unit display: Switchable between MPa, kPa, psi, bar, kgf/cm², etc.
   • Various display modes: Can show real-time pressure, output current percentage, range upper and lower limits, etc.
   • Diagnostics and alarms: The screen can indicate over-range, sensor failure, communication errors, and other statuses, and limit value alarm indications can be set.
   • Data logging: Some advanced models support minimum/maximum value recording and trend curve display.
4. Supports Multiple Communication and Configuration Methods
   • Button operation: Local settings can be made through the buttons on the gauge body.
   • Infrared/magnetic induction operation: No need to open the cover; operations can be performed outside the explosion-proof housing using an infrared remote control or an external magnetic pen, ensuring high safety.
   • HART/bus hand controller: Retains the same remote configuration method as traditional smart transmitters.
   • Bluetooth/Wi-Fi: New models support wireless near-field configuration and data reading, operable through a mobile phone app.

1. Near critical equipment: At the outlets of air compressors, refrigeration units, water pumps, compressors, etc., for the convenience of operators during inspection rounds.
2. Distributed sites: Pump stations and pipeline monitoring points far from the control room, where on-site personnel need to independently read data.
3. Frequent commissioning and maintenance scenarios: Experimental devices, test platforms, and the commissioning stage of production lines.
4. Scenarios requiring high-precision on-site readings: Quality inspection, calibration stations, and energy metering points.
5. Replacing the traditional installation mode of "pressure gauge + transmitter": It has become a trend in new project design and renovation.

Digital display pressure transmitters represent a clear trend of "intelligence, integration and humanization" in industrial field instruments. They are not merely equipped with a screen, but fundamentally change the way field personnel interact with the instruments, significantly enhancing work efficiency, maintenance convenience and system integration.
