A pressure transmitter converts pressure signals from gases or liquids into standard electrical outputs such as 4-20mA, 0-10V, or RS485, enabling monitoring and control in industrial automation systems. It is widely used in hydraulic systems, energy equipment, and process control applications.
When selecting a pressure transmitter, consider pressure range, media type, accuracy, output signal, and working conditions such as high temperature, corrosion, or explosion-proof requirements. For example, micro pressure applications require micro pressure transmitters, while high-temperature environments need high-temperature models.
A micro pressure transmitter is designed for low-pressure measurements (Pa level) with higher sensitivity and resolution, while standard pressure transmitters are typically used for higher pressure ranges such as bar-level applications.
Differential pressure transmitters measure the pressure difference between two points and are widely used in filtration monitoring, wind tunnel testing, flow measurement, leak detection, and HVAC systems.
Common output signals include 4-20mA, 0-5V, 0-10V, 1-5V, as well as digital outputs like RS485 (Modbus RTU) and CANopen, meeting various industrial control system requirements.
High-temperature pressure transmitters can operate stably in environments ranging from 150°C to 350°C or higher, depending on design, and are commonly used in steam systems, melt processes, and petrochemical industries.
Accuracy levels typically include ±0.5%F.S, ±0.25%F.S, and ±0.1%F.S or higher. High-precision applications such as laboratories or aerospace require sensors with ±0.1%F.S or better accuracy.
Pressure transmitters are widely used in industrial automation, hydraulic systems, energy equipment, medical devices, construction machinery, environmental monitoring, and scientific research.
Yes, most industrial pressure sensor manufacturers support OEM customization, including pressure range, output signals, mechanical interfaces, and housing design to meet specific project requirements.
High-quality pressure transmitters offer excellent long-term stability, with annual drift typically below 0.05%F.S, making them suitable for continuous industrial operation.
