常见问题（FAQ）
Q1: What is the working principle of a pressure transmitter?
A pressure transmitter detects pressure changes using sensing elements (such as piezoresistive silicon chips) and converts them into electrical signals like 4–20mA, 0–10V, or RS485 digital outputs for real-time monitoring and control.
Q2: How to choose the right pressure transmitter model?
You should consider pressure range, accuracy, output signal, medium type, and installation. For example, STG15 is suitable for high-pressure applications, flush diaphragm types for corrosive media, and differential transmitters for pressure difference measurement.
Q3: What are the common output signals of pressure transmitters?
Common outputs include 4–20mA, 0–5V, and 0–10V analog signals, as well as digital communication protocols such as Modbus RS485 and CANopen for industrial automation systems.
Q4: Where are explosion-proof pressure transmitters used?
Explosion-proof pressure transmitters are widely used in hazardous environments such as oil & gas, chemical plants, mining, and other areas with flammable or explosive conditions.
Q5: What are the applications of differential pressure transmitters?
They are mainly used in flow measurement, filter monitoring, level control, and pipeline pressure difference detection in industries such as water treatment, power plants, and automation systems.
Q6: What is the maximum pressure range of high-pressure sensors?
High-pressure sensors like STG15 can measure pressures up to 6000 bar, suitable for waterjet systems, hydraulic equipment, and high-pressure testing applications.
Q7: What are the advantages of integrated temperature and pressure transmitters?
They can measure both pressure and temperature simultaneously, saving installation space and improving system integration, ideal for complex industrial environments.
Q8: How to choose the accuracy level of a pressure transmitter?
Accuracy levels typically include ±0.5% F.S, ±0.2% F.S, and ±0.1% F.S. Higher accuracy is suitable for precision measurement applications such as laboratory instruments and control systems.
Q9: What media can pressure transmitters measure?
They can measure gases, liquids, and oils. For corrosive media, it is recommended to use transmitters with 316L materials or flush diaphragm designs.
Q10: Do you support OEM customization for pressure sensors?
Yes, OEM customization is supported, including pressure range, connection type, output signal, and housing design to meet various industrial requirements.
