Against the backdrop of increasingly scarce water resources, water-saving irrigation technology has become a core pathway for sustainable agricultural development. Especially in arid regions such as Xinjiang, where day–night temperature differences are large and rainfall is scarce, efficient utilization of limited water resources is crucial. Pressure sensors ensure balanced water distribution by real-time monitoring of irrigation pipeline pressure, preventing waste or insufficiency. Nexisense pressure sensors serve this field with reliable performance, providing full-process control from drip irrigation to sprinkler irrigation, helping alleviate water resource pressure and promote precision agriculture.

Definition and Function of Pressure Sensors

A pressure sensor is a device that converts medium pressure into standard electrical signals. In water-saving irrigation, it mainly monitors pipeline, pump, and dripper pressure to ensure that the system operates within optimal parameters. It supports automated regulation, preventing pipeline rupture due to overpressure or clogging caused by low pressure, and achieves precise allocation of water resources.

Nexisense products are suitable for wide altitude ranges and extreme temperature difference environments, supporting efficient agricultural water use in arid regions.

Working Principle Analysis

Nexisense pressure sensors are based on diffused silicon or ceramic sensing element principles. Pressure acts on an isolation diaphragm, causing deformation of the sensitive element and generating an electrical signal. After amplification and temperature compensation by built-in circuits, standard signals such as 4–20 mA are output. These signals are transmitted to controllers, which adjust valves or pump speed according to preset thresholds.

Under the large temperature difference conditions in Xinjiang, the built-in compensation mechanism minimizes drift and ensures stable measurement.

Internal Structure Analysis

The structure includes a stainless-steel diaphragm, a sensitive sensing element, and a signal processing module. The diaphragm directly contacts the water medium, offering corrosion resistance and easy cleaning. The housing provides a protection level of IP65 or higher, ensuring dustproof and moisture-proof performance. Interfaces support threaded connections or quick connectors, facilitating field installation.

The compact design adapts to long-term outdoor exposure and reduces maintenance requirements.

Outstanding Advantages

Nexisense pressure sensors feature strong anti-interference capability, high overload resistance, impact resistance, minimal temperature drift, and excellent stability. Even with altitude differences of 100 meters or under extreme climate conditions, they maintain high accuracy. Fast response supports real-time control and is suitable for large-scale irrigation networks.

These characteristics are particularly evident in water-scarce regions, helping achieve uniform irrigation and reduce evaporation losses.

Application Scenarios in Water-Saving Irrigation

In drip irrigation systems, sensors monitor main and branch pipeline pressure to ensure uniform water output from drippers, avoiding localized drought or waterlogging. In sprinkler irrigation applications, pump station pressure is monitored to optimize sprinkler coverage.

In Xinjiang cotton fields, orchards, and other crop plantations, sensors work with intelligent controllers to automatically adjust water volume based on soil moisture. For fields with large altitude differences, multi-point monitoring compensates for pressure variation, achieving balanced water supply and promoting water-saving and yield-increasing agriculture.

Measurement Methods and Installation Specifications

Measurement mainly adopts gauge pressure mode with direct pipeline connection. During installation, when the interface faces upward or sideways, it is necessary to prevent liquid from entering the housing and avoid moisture blocking the vent. Electrical connections should be kept clean and dust-free.

When the measurement range is less than 0.03 MPa, vertical installation is required (except for gas measurement); other angles are flexible. If the interface does not match, custom adapter fittings can be used. The installation position should be selected at points with stable pressure, away from interference caused by bends or valves.

Maintenance and Care Guidelines

Xinjiang is dry and dusty; therefore, diaphragms and vent ports should be cleaned regularly to prevent dirt accumulation. Check seal integrity to prevent sand and dust intrusion. Under extreme temperature differences, monitor zero-point drift and perform calibration once a year.

Implement antifreeze measures in winter and sun shading in summer. Store equipment in dry and ventilated environments. These measures ensure long-term effective operation and reduce failure rates.

Technical Specifications Overview

Typical Nexisense specifications include: measurement range from 0–0.1 MPa to 10 MPa; accuracy ±0.5% FS; output 4–20 mA or digital signals; operating temperature -40°C to 85°C; overload capacity 150% FS; protection rating IP65–IP67; material 316L stainless steel.

Other Optimization Techniques

By combining flow sensors and soil moisture probes, a multi-parameter intelligent system can be formed. Wireless transmission options support remote monitoring and reduce field inspections. Software algorithms compensate for altitude-induced pressure differences, further improving accuracy.
