1.Product Overview
The smart differential pressure transmitter is specifically designed for precise measurement of differential pressure between two pressure points. It converts differential pressure values into standard industrial signals for applications such as flow calculation, liquid level monitoring, filter condition monitoring, and pipeline leak detection.
Compared to traditional differential pressure transmitters, the intelligent model incorporates advanced features such as self-diagnostics, remote calibration, digital communication, and intelligent compensation. These capabilities significantly enhance measurement accuracy, stability, and reliability while reducing maintenance costs, making it well-suited for complex and dynamic industrial environments.
2.Product Advantages
Utilizes second-generation monocrystalline silicon composite sensors or capacitive sensors with optimized diaphragm structures, achieving measurement accuracy of ±0.075% while maintaining precise response in low differential pressure scenarios;
Long-term stability exceeds 0.1%/year, reducing calibration frequency;
Robust environmental adaptability with IP67 protection rating and electromagnetic interference resistance;
Supports 4–20mA current signal output with superimposed HART digital signal, offering strong EMI resistance; select models can be customized with LoRaWAN communication;
Enables remote parameter setting and calibration via HART, Modbus, and other protocols, eliminating on-site operation;
Built-in EEPROM non-volatile memory retains calibration data after power loss, with raw data recovery capability;
Maximum turndown ratio of 100:1 covers measurement requirements from micro-differential pressure (0-1kPa) to high-differential pressure (0-10MPa);
Integrated temperature and pressure nonlinearity compensation algorithms eliminate environmental impacts on measurements;
Monitors sensor, circuit, and communication status, triggering alarms within 100 milliseconds and storing fault information;
Isolation diaphragms made of 316L stainless steel, Hastelloy, or tantalum for corrosive media applications;
Stores critical measurement data and event logs for traceability and analysis.
