PM270 Ceramic Capacitive pressure (level) transmitter
Product Applications
I. Chemical and Process Industry
Storage and transportation of highly corrosive chemicals
Application scenarios: Pressure and liquid level measurement of storage tanks for concentrated sulfuric acid, concentrated hydrochloric acid, caustic soda (NaOH), organic solvents, etc.
Reactor pressure monitoring
Application scenarios: high-pressure/high-temperature chemical reaction processes such as polymerization, nitrification, and oxidation.
Pipeline flow measurement
Application scenario: Calculate the flow rate of corrosive media by measuring the pressure difference before and after the throttling element (such as a orifice plate).
Ii. Water Treatment and Environmental Protection
Sewage treatment plant (aeration tank, dosing system, sludge treatment site) :
Application scenario: Monitoring the outlet pressure of the aeration blower; Monitor the inlet and outlet pressures of the sludge transfer pump and dosing pump.
Water level monitoring of rivers and lakes
Application scenario: Fix the submersible level transmitter underwater for long-term monitoring of water level changes.
Iii. Food, Beverages and Pharmaceuticals
Pressure monitoring of CIP/SIP cleaning process
Application scenarios: Monitoring the pressure of high-temperature cleaning solutions and saturated steam during online cleaning and online sterilization processes.
Measurement of high-viscosity media (syrup, jam) :
Application scenarios: Liquid level measurement in storage tanks, pressure monitoring in conveying pipelines.
Iv. Energy and HVAC
Boiler system, heat exchange station
Application scenarios: Monitoring boiler feed water pressure, steam pressure, and primary/secondary side pressure of heat exchangers.
Compressed air system
Application scenarios: Pressure monitoring of air compressor outlets, air storage tanks, dryers and pipeline networks.
V. Heavy Machinery and Hydraulics
Construction machinery, injection molding machines, presses
Application scenarios: Integrated into the hydraulic system, injection system or main oil circuit of the equipment, used for pressure feedback and control.
Vi. Research and Verification
Used as a standard meter or for laboratory measurement:
Application scenario: It is used as a pressure standard in the metrology room to calibrate other industrial pressure gauges. Measure the reaction pressure in precise laboratory experiments.
