SJ Gauge pressure transmitters for industrial process monitoring

Pressure Sensors (Transducers/Transmitters)

An intelligent pressure transmitter is a highly precise pressure measurement device equipped with digital functionality. It converts measured pressure values into standard electrical signals (such as 4–20 mA) or digital signals, and supports various communication protocols including HART and Modbus.

This device is widely used in automation control systems, especially in industrial environments that require remote monitoring and high accuracy. If you would like to learn more about specific models or require product customization, please provide your detailed requirements, and we will offer tailored recommendations.

Pressure Sensors and Transmitters FAQ

Questions for choosing pressure transmitters, smart transmitters, flush diaphragm transmitters, and wireless pressure monitoring.

How do I choose a pressure transmitter?
Select by pressure range, accuracy, process media, output signal, electrical connection, process connection, temperature, and installation environment. General industrial models suit standard applications, while flush diaphragm, high-temperature, or aggressive-media versions are used for difficult media.
When is a flush diaphragm transmitter needed?
A flush diaphragm transmitter is recommended for viscous, particle-laden, hygienic, or media-prone-to-clogging applications. It reduces dead space and helps keep the sensing surface cleaner than a standard threaded port.
What output signal should I choose for a pressure transmitter?
4-20mA is common for industrial analog transmission, HART adds smart communication and configuration, RS485 or Modbus supports digital networks, and wireless transmitters are useful when cabling is difficult. Choose based on the control system and monitoring distance.
Can pressure transmitters be used in high temperature or corrosive media?
Yes, but the model and material must match the process. High-temperature applications may require remote seals or special transmitter designs, while corrosive media may require ceramic sensors, PVDF/PTFE interfaces, or diaphragm seal assemblies.
