Plastic Pressure Transmitters
Plastic Pressure Transmitter is a device with a plastic body used to measure liquid or gas pressure. Such transmitters are preferred especially in environments where corrosion resistance is required or when lightweight and cost-effective solutions are desired.
Features of Plastic Pressure Transmitters
Material Used in the Body:
Corrosion-resistant plastics such as PVC, PP (polypropylene), PTFE (teflon) or PVDF are mostly used. This provides long life in environments containing chemicals.
Measurement Accuracy:
It generally offers an accuracy ranging from ±0.1% to ±0.5%. It is suitable for precise measurements.
Pressure Measurement Range:
It can operate in 0-10 bar, 0-16 bar or higher ranges. The pressure range is selected according to the application.
Connection Type:
Input/output connections can be plastic threaded or flanged.
Process connections are in standard sizes (e.g. 1/4" NPT, 1/2" NPT).
Temperature Resistance:
Due to plastic material, it can generally be used at temperatures up to 80°C. However, special models can withstand higher temperatures.
Output Signal:
It can provide analog (4-20 mA, 0-10 V) or digital (HART, Modbus) output signals.
Protection Class:
It is produced in IP65, IP67 or IP68 protection class. This ensures safe use in outdoor or water-exposed environments.
Areas of Use:
Chemical storage tanks.
Water treatment systems.
Swimming pools and SPA applications.
Food and beverage industry.
Environmental control systems (e.g. wastewater facilities).
Advantages of Plastic Pressure Transmitters
Corrosion Resistance: Safe use in environments where corrosive chemicals are present.
Lightweight: Plastic housing facilitates portability and installation of the device.
Economical: It is less costly than metal-bodied transmitters.
Flexibility: It can be used in various applications.
