pressure transmitter
Pressure transmitter is a measuring instrument that converts a felt pressure signal into a standard electrical signal output. In pneumatic conveying systems, pressure transmitters are used to monitor and control the gas pressure in the pipeline to ensure that materials can be transported efficiently and safely under the correct pressure conditions.
Principle
Pressure sensing: The sensor (such as strain gauge, capacitive, etc.) inside the pressure transmitter senses the gas or liquid pressure in the pipeline.
Signal conversion: The sensor converts changes in pressure felt into electrical signals (changes in voltage or resistance).
Signal processing: The internal circuit amplifies and linearizes the original electrical signal to ensure that the output signal accurately reflects the actual pressure value.
Standardized output: The processed signal is converted into a standard electrical signal format (such as 4-20mA, 0-10VDC), which facilitates long-distance transmission and integration with other control systems.
Real-time monitoring: The output standard signal is connected to PLC, SCADA system or other monitoring equipment to achieve real-time pressure monitoring and control.
Feedback adjustment: Based on the received pressure data, the control system can automatically adjust the operating parameters of related equipment (such as fans, compressors, valves, etc.) to maintain stable operation of the system. Parameter
