Q: What is a differential pressure transmitter and how does it work?
A: A differential pressure transmitter measures the pressure difference between two points. This industrial DP transmitter uses a monocrystalline silicon sensor to detect the differential pressure and converts it to a standard output signal for monitoring and control applications.

Q: How does the monocrystalline silicon differential pressure transmitter differ from standard models?
A: The SMP7701 monocrystalline silicon differential pressure transmitter offers higher accuracy, better stability, and includes HART protocol communication, enabling remote configuration and diagnostics. It is ideal for demanding applications requiring smart differential pressure transmitter capabilities.

Q: Can the micro differential pressure transmitter handle corrosive gases?
A: The SMP7003 micro differential pressure transmitter is designed for non-corrosive clean gas pressure measurement. For corrosive media, please consider our other differential pressure transmitter models with suitable materials.
