Pressure sensors and pressure transmitters are essential components in industrial automation and process control systems, designed for accurate pressure measurement and signal transmission of gases, liquids, and steam. They are widely used in hydraulic systems, air compressors, water treatment, engineering machinery, energy equipment, petrochemical industries, food processing, pharmaceutical systems, and intelligent manufacturing applications. Modern industrial pressure transmitters typically utilize high-stability diffused silicon, ceramic, or MEMS sensing elements, offering high accuracy, long-term reliability, excellent anti-interference capability, vibration resistance, corrosion resistance, and wide temperature operation. Multiple output options such as 4-20mA, 0-10V, 0.5-4.5V, RS485 Modbus RTU, and HART communication are available to meet diverse industrial pressure monitoring requirements.

Frequently Asked Questions (FAQ)

Q1: Do you support custom pressure transmitter solutions?

Yes, OEM/ODM customization is available, including pressure range, output signals, connection types, materials, and special application requirements.

Q2: What IP ratings do industrial pressure transmitters have?

Typical protection ratings include IP65, IP67, and IP68, ensuring reliable operation in outdoor, humid, and harsh industrial environments.

Q3: What media can pressure transmitters measure?

Pressure transmitters can measure gases, liquids, and oils. Some models are suitable for corrosive or viscous media (such as acids and alkalis), depending on material compatibility.

Q4: What output signals do pressure transmitters support?

Common outputs include 4–20mA, 0–5V, 0–10V, mV signals, and digital communication protocols such as RS485 (Modbus), CANopen, and HART.

Q5: How accurate are high-precision pressure transmitters?

High-precision pressure transmitters (such as STG50) can achieve accuracy up to ±0.01% F.S, suitable for metrology, aerospace, and high-end industrial automation.

Q6: What are differential pressure transmitters used for?

Differential pressure transmitters are widely used for flow measurement, level monitoring, filter pressure drop detection, and leak testing, enabling precise pressure difference monitoring.

Q7: Where are explosion-proof pressure transmitters used?

Explosion-proof pressure transmitters are used in hazardous environments such as mining, oil & gas, and chemical industries, ensuring safe operation with intrinsically safe or flameproof designs.

Q8: Which pressure transmitter is suitable for high-temperature environments?

For high-temperature applications (e.g., -50°C to 168°C), a dedicated high-temperature pressure transmitter (such as STG40) with temperature compensation and corrosion-resistant design is recommended.

Q9: How to choose the right industrial pressure transmitter?

You should consider pressure range, measurement type (gauge/absolute/differential), accuracy, output signal, mechanical connection, and application environment (such as high temperature, explosion-proof, or corrosive media).

Q10: What is the difference between a pressure transmitter and a pressure sensor?

A pressure sensor converts pressure into a raw electrical signal, while a pressure transmitter further processes and amplifies the signal to output standard industrial signals (such as 4–20mA or 0–10V), making it suitable for automation systems.
