| Product Overview
The WCPS300 series fully anti-corrosion pressure sensor/transmitter researched and produced by winchen sensor is a dedicated instrument developed for pressure measurement of highly corrosive media. It uses PTFE, PP, PVDF and other anti-corrosion materials as wetted parts, ensuring long-term stable operation in extremely corrosive environments such as hydrochloric acid, sulfuric acid, nitric acid, chlorine gas, electrolyte, seawater and strong alkalis.
This series strictly follows ISO9001 and metrology certification standards and is widely used in chemical reactors, pharmaceutical liquid preparation systems, electroplating lines, environmental wastewater treatment, oil extraction and seawater desalination, making it the ideal choice for pressure monitoring of corrosive media.
| Features
1. Superior corrosion resistance: almost the entire body uses PTFE, PP, PVDF and other anti-corrosion materials, providing protection against both the medium and the environment.
2. High accuracy and high stability: imported diffused silicon or ceramic pressure sensor chips combined with advanced signal processing circuits give accuracy up to±0.25%FS, and long-term stability≤±0.1%FS/year;
3. Multiple threaded connections: supports G1/2, G1/4, M20××1.5 and other standard threads, with special threads customizable to customer requirements;
4. Diverse signal output: supports 4~20mA (two-wire), 0~5V, 0~10V, RS485 and other output modes, compatible with various industrial control systems;
5. Strong anti-interference capability: isolated circuit design with over-current, over-voltage and reverse-polarity protection, remaining stable and reliable even in industrial sites with severe electromagnetic interference;
6. Wide operating temperature range: temperature range -40~125°C, meeting the requirements of both high- and low-temperature working conditions;
7. Compact and easy to install: compact structure and threaded connection allow quick on-site installation without complex commissioning;
