| Product Introduction

The WCPS400 series high-precision monocrystalline silicon pressure transmitter has an accuracy of up to 0.075%FS and an Ex ia IIC T6 Gb explosion-proof rating, with flange and threaded mounting options. In terms of circuit design, it adopts a modular design centered on a microprocessor and assisted by advanced digital isolation technology, giving it extremely high anti-interference capability and stability. At the same time, it uses digital compensation technology to compensate for temperature and static pressure, improving measurement accuracy and reducing temperature drift. It features good long-term stability, high reliability and strong self-diagnostic capability, and is suitable for high-temperature and explosion-proof occasions such as petroleum, chemicals and heating network supply.

| Functional Features

1. Ultra-high accuracy: accuracy class up to±0.075%FS, and can even reach±0.05%FS accuracy;

2. Ultra-wide range and turndown ratio: extremely wide measurement range, from 100Pa~40MPa, with a turndown ratio as high as 100:1;

3. Explosion-proof rating: Ex ia IIC T6 Gb (intrinsically safe certification);

4. Extremely low drift, long-term stability: extremely strong creep resistance, fundamentally suppressing zero drift, stability can be maintained at 0.1%FS/10 years;

5. Excellent linearity: the strain and resistance change of monocrystalline silicon have a highly linear relationship; linearity is improved by 50% compared with traditional metal strain gauges, making measurement more precise;

6. Rich communication and protocols: supports multiple communication protocols such as HART, RS485 and Modbus, facilitating remote parameter setting, process monitoring and system integration;

7. Intelligent functions: integrated self-diagnostic function for real-time monitoring of sensor health; supports one-key factory reset and local/remote configuration;
