Pressure Sensors (Transducers/Transmitters) (16)
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.

Differential Pressure Gauge (6)
A differential pressure gauge is a specialized instrument designed to measure the pressure difference between two points, allowing users to directly read the differential pressure value and monitor system operating conditions in real time. These gauges are especially suitable for applications that require precise monitoring of pressure changes and fluid conditions. Common applications include filter clogging monitoring, pump operation monitoring, heat exchanger pressure loss measurement, pipeline differential pressure monitoring, duct systems, cleanroom pressure control, and HVAC systems. If you would like to learn more about differential pressure gauge specifications, measuring ranges, connection types, or customized solutions, please share your application requirements with us. SJ Gauge will be glad to help you identify the most suitable solution. -
Contact Pressure Gauge (6)
This instrument combines real-time monitoring with automated control, allowing users to set upper and lower pressure limits. When the system pressure reaches these predefined values, it automatically triggers electrical signals to start or stop associated equipment, serving as an essential control component in industrial automation and safety protection. -
Diaphragm Seal (29)
SJ Gauge offers a wide range of diaphragm seal solutions for pressure gauges and pressure transmitters, including single flange, double flange, sanitary type, threaded type, and special diaphragm seals, which can be selected based on different media characteristics and installation requirements. When the measured media is viscous, paste-like, crystallizing, particle-containing, or highly corrosive, diaphragm seals help protect pressure instruments by reducing the risk of clogging, corrosion, and damage, while improving measurement stability. Common applications include chemical processing, food and beverage, pharmaceutical, wastewater treatment, petrochemical, and various process industries. If you have special operating conditions or customization requirements, please feel free to contact SJ Gauge. -
