Core Technology Analysis: A Stable Link from Sensing to Output

Application Advantages of Ceramic Pressure Cores

Compared with traditional diffused silicon solutions, ceramic pressure cores possess good corrosion resistance and long-term stability, particularly suitable for water treatment, water supply systems, and some weakly corrosive media environments. Its structure does not require oil-filled isolation, which helps reduce the risk of leakage while simplifying the internal structural design.

Highly Reliable Signal Conditioning Circuit

The WPCH01 features a built-in high-stability amplification circuit that linearly amplifies weak pressure electrical signals. Through precision compensation algorithms, it corrects temperature drift and non-linear errors, thereby outputting stable and continuous standard signals.

Supported output formats include:

• 4-20mA (Industrial standard current signal)

• 0-5V / 0.5-4.5V (Voltage output)

This diverse range of output methods makes it compatible with PLCs, DCS systems, and embedded control platforms.

Temperature Compensation Mechanism

In practical applications, temperature changes affect sensor output. The WPCH01 maintains good measurement consistency within the default 0-65°C range through precision temperature compensation technology and supports extended customization to adapt to more complex environmental conditions.

Selection Suggestions: How to Match Actual Application Needs

When choosing a pressure transmitter, it is recommended to focus on the following factors:

Range Selection

It is recommended to select 1.5 to 2 times the actual working pressure as the range to balance precision and safety margin.

Output Signal Matching

Prioritize 4-20mA for industrial sites. For embedded systems, voltage output can be selected.

Environmental Adaptability

Choose appropriate compensation ranges and material structures based on working temperature, humidity, and media characteristics.

Frequently Asked Questions (FAQ)

1. How to choose between ceramic pressure cores and diffused silicon cores?

Ceramic cores are suitable for water, air, and weakly corrosive media, offering good corrosion resistance and stability; diffused silicon cores are more suitable for high-precision or high-dynamic pressure application scenarios. Selection should be based on media and precision requirements.

2. Does the WPCH01 support long-term outdoor use?

Under IP67 protection conditions, it can be used in general outdoor environments, but it is recommended to add protective measures (such as waterproof joints and shielding structures) to extend service life.

3. How to choose between 4-20mA and 0-5V output?

4-20mA is suitable for long-distance transmission and industrial environments with high anti-interference requirements; 0-5V is more suitable for short-distance, low-power applications.

4. How to avoid the impact of pressure shocks on the sensor?

It is recommended to add buffer devices or throttle holes in the system to reduce the impact of instantaneous pressure fluctuations on the sensor.

5. How is the long-term stability of the product guaranteed?

The WPCH01 controls drift through temperature compensation and high-stability circuit design. Periodic calibration is also recommended to ensure long-term accuracy.

6. Is OEM custom development supported?

Yes. Housing structures, interface forms, electrical parameters, etc., can all be adjusted according to project needs.

7. What should be noted when using in high-temperature environments?

Confirm whether the operating temperature range covers the actual working conditions. It is also recommended to use an extended temperature compensation version to reduce the impact of temperature drift.
