B. Working Principle
The transmitter uses the piezoresistive effect to convert applied pressure into an electrical measurement.
Pressure Detection: Liquid or gas pressure acts on the 316L stainless steel isolation diaphragm.
Sensing and Conversion: Pressure-induced deformation changes the resistance of the diffused silicon sensing element.
Signal Processing: Internal electronics amplify and compensate the signal for stable measurement.
Signal Transmission: The processed value becomes a configured 4 to 20 mA, RS485 or voltage output.
Digital Display: LCD or LED variants show pressure directly at the instrument.
Automation Integration: Compatible PLC, SCADA and controllers use the signal for monitoring, alarms and automated control.
Example: For a 0 to 10 bar transmitter with linear 4 to 20 mA output, 0 bar gives 4 mA, 5 bar gives 12 mA and 10 bar gives 20 mA.
C. Why Is the RDCL Industrial Pressure Transmitter Used?
Continuous pressure measurement helps improve process monitoring, operating efficiency and equipment protection.
1. Water Treatment and Water Supply Systems
Monitors pressure in treatment plants, filtration equipment, pipelines and pumping stations. It helps identify abnormal pressure and maintain operating conditions.
2. Hydraulic Pressure Monitoring
Measures pressure in hydraulic power packs, pumps, actuators and machinery. The signal provides feedback to detect unexpected changes in operating pressure.
3. Industrial Process Automation
Supplies pressure signals to PLCs, SCADA and controllers for centralized monitoring, alarms and automatic process control.
4. Pump and Compressor Monitoring
Measures inlet or outlet pressure in pumps and compressors, supporting operating checks and automated control through external equipment.
5. HVAC and Building Management Systems
Monitors pressure in chilled-water lines, hot-water circulation and compatible air-pressure applications. Readings can support BMS monitoring and control.
6. Chemical and Petrochemical Processing
Measures pressure in compatible tanks, pipelines and process equipment. Verify fluid compatibility with the 316L stainless steel diaphragm and other wetted parts.
7. Liquid Level Monitoring
In suitable open tanks, hydrostatic pressure can be used to estimate liquid level when liquid density and installation conditions are known.
8. Industrial Safety and Equipment Protection
Helps detect high pressure, sudden drops and other abnormal conditions. Properly configured external control systems can generate alarms or protective actions.
