Nexisense Diffused Silicon Pressure Transmitter: A Reliable Partner for Industrial Monitoring

Product Overview

The Diffused Silicon Pressure Transmitter uses the piezoresistive effect with a diffused silicon sensitive element as its core. Nexisense products are optimized for industrial applications with wide temperature compensation and corrosion-resistant structures, suitable for various media and environments.

With increasing industrial pressure monitoring demands, temperature changes and corrosive media often cause measurement deviation. Nexisense transmitters address these challenges in their design, ensuring long-term stability and proven reliability in numerous enterprises.

Measurement Principle

The transmitter operates on the piezoresistive principle: media pressure acts on the silicon diaphragm, changing the crystal resistance and forming a Wheatstone bridge signal. This signal is amplified and compensated to output a standard 4–20 mA current.

Built-in wide temperature compensation automatically corrects thermal drift, and non-linearity correction improves accuracy. The fast response is suitable for dynamic pressure monitoring. This technology is compatible with gases and liquids, offers linear output, and integrates easily with control systems.

Main Advantages

The Nexisense Diffused Silicon Pressure Transmitter excels in industrial applications. First, it provides strong temperature stability: wide temperature compensation ensures reliable data in seasonal changes or outdoor environments, reducing calibration frequency.

Second, excellent corrosion resistance: full stainless steel construction resists acid, alkali, and oil corrosion, suitable for harsh media. IP67 protection handles humid and dusty environments, extending service life.

High accuracy and stability: quickly captures pressure changes with minimal long-term drift, suitable for demanding applications. Reverse polarity protection prevents damage from wiring errors, making the device versatile and simplifying inventory management.

Application Scenarios

The diffused silicon pressure transmitter is widely used in industrial settings:

• Factory production lines: provides real-time pressure feedback for automated control, preventing overpressure risks.

• Water treatment systems: monitors pump stations and pipeline pressure; corrosion resistance ensures stable operation in wastewater environments.

• Hydraulic and pneumatic control: precise data helps optimize systems and prevent leaks or faults.

• Other scenarios: industrial machinery manufacturing, compressed air systems, and process control. Nexisense products adapt flexibly, enhancing monitoring capabilities.
