FAQ
Q: What is the difference between a general-purpose pressure transmitter and a standard pressure sensor?
A: A general-purpose pressure transmitter is a complete industrial device with built-in signal conditioning. It directly outputs standard signals such as 4–20 mA or voltage output, allowing direct connection to a PLC or controller and enabling immediate use out of the box. In contrast, a bare pressure sensor core requires additional circuitry before it can be used in a system.
Q: Which pressure type should I choose?
A:
-
Absolute pressure uses a vacuum reference and is suitable for applications such as altitude compensation and atmospheric pressure measurement.
-
Sealed gauge pressure uses a fixed sealed reference pressure and is commonly used in high-pressure systems.
The appropriate pressure type should be selected based on the specific measurement requirements of your application.
Q: Can the high-temperature version really withstand 400°C?
A: Yes. The SMF6352 Series high-temperature pressure transmitter uses sapphire sensing technology and a fully welded structure. It is specifically designed for extreme high-temperature environments and can operate reliably at temperatures up to +400°C. It is suitable for industrial furnaces and other high-temperature process applications.
