Nexisense Compact Pressure Sensor: Reliable Industrial Pressure Monitoring

Product Overview

The Nexisense compact pressure sensor is optimized for industrial applications, offering powerful functionality in a small footprint. It features a full stainless steel housing, with high-quality ceramic piezoresistive sensing elements processed with precision and laser calibration, enabling accurate calibration across a wide temperature range. This design ensures long-term stability in harsh environments, making it a trusted choice for industrial pressure monitoring.

With the development of the Industrial Internet of Things, pressure sensors are no longer simple data collectors but critical nodes for system stability. Nexisense sensors maintain compact size while integrating advanced circuitry and protection mechanisms to handle demanding field conditions.

Working Principle and Measurement Method

The compact pressure sensor operates on the piezoresistive effect. The ceramic sensing element deforms slightly under pressure, and the built-in Wheatstone bridge converts the deformation into a millivolt electrical signal, which is amplified and output as a standard 4-20mA or 0-5V signal.

The measurement process includes: the medium’s pressure acts on the isolation diaphragm and transfers to the ceramic element; resistance changes generate a signal; and internal digital circuitry performs temperature compensation and linearization, ensuring a linear output corresponding to pressure. Ceramic piezoresistive technology provides strong medium compatibility and corrosion resistance, suitable for both gas and liquid measurement.

The Nexisense sensor also features digital compensation algorithms, automatically correcting temperature drift from -20°C to 80°C for high-precision output. Compared to traditional silicon sensors, the ceramic element is more impact- and overpressure-resistant, enhancing field reliability.

Structural Analysis

The Nexisense compact pressure sensor has a durable and refined structure. The pressure chamber is stainless steel with laser welding for zero leakage. The high-elasticity ceramic element resists wear, impact, and vibration, with excellent corrosion resistance.

The electronic module integrates strong anti-interference protection, including lightning, RF, surge, and reverse polarity protection. The fully stainless steel housing achieves IP67 protection, resisting dust, moisture, and vibration. These design features ensure long-term sensor safety and reliability.

Application Scenarios

The Nexisense compact pressure sensor is widely used in industrial applications. In pump systems, it monitors inlet and outlet pressure to prevent overload or dry running. In hydraulic and pneumatic pipelines, it provides precise pressure feedback for accurate system control, avoiding leakage risks.

In urban smart networks, sensors monitor water supply pipelines, detect pressure fluctuations, and provide early warning of pipe bursts or leaks, enabling remote operation. In water treatment, they monitor filters, pump stations, and storage tanks, with corrosion-resistant materials suitable for sewage or chemical media.

Other applications include compressed air systems, refrigeration equipment, and process control. Its compact size and robust performance make it a core component for smart factory pressure monitoring.
