Frequently Asked Questions (FAQ)

Q1: How stable are pressure transmitters over time?

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.

Q2: Do you support OEM customization for pressure sensors?

Yes, most industrial pressure sensor manufacturers support OEM customization, including pressure range, output signals, mechanical interfaces, and housing design to meet specific project requirements.

Q3: What industries use pressure transmitters?

Pressure transmitters are widely used in industrial automation, hydraulic systems, energy equipment, medical devices, construction machinery, environmental monitoring, and scientific research.

Q4: How to choose the accuracy level of a pressure transmitter?

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.

Q5: What temperature can high-temperature pressure transmitters withstand?

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.

Q6: What output signals do pressure transmitters support?

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.

Q7: What applications are differential pressure transmitters used for?

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.

Q8: What is the difference between a micro pressure transmitter and a standard pressure transmitter?

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.

Q9: How to choose the right pressure transmitter?

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.

Q10: What is the function of a pressure transmitter?

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.
