Nexisense Wireless Temperature & Pressure Transmitter: Industrial-Grade Integrated Solution

The Nexisense wireless temperature and pressure integrated transmitter is specifically designed for industrial automation and IoT projects. It combines temperature compensation and pressure measurement functions, and through a self-developed low-power wireless transmission module, enables real-time field data transmission to cloud platforms. This series supports multiple wireless communication protocols, features a compact and robust structure, and meets both explosion-proof requirements and high-precision measurement needs, making it ideal for large-scale deployment in complex industrial environments.

Core Technical Features

The product adopts an explosion-proof cast aluminum housing with 304 stainless steel connections. It integrates a high-precision silicon pressure-sensitive chip and temperature compensation module, making it compatible with gas, liquid, and oil media. Inside the pressure measuring sleeve, a cylindrical anti-vibration grille and filter are installed. A fluid buffer channel is reserved in front of the filter, effectively reducing medium impact and enabling self-cleaning, thereby extending the service life of the isolation diaphragm and improving measurement stability.

The PCB integrates a microprocessor, rechargeable battery, wireless transmission module, and antenna. It supports adjustable sampling rates, configurable data upload frequency, customizable high/low pressure alarm thresholds, and real-time pressure alarms. The LCD display provides functions such as zero calibration, backlight, unit switching, and low voltage alarm. Overall power consumption is controlled at the milliwatt level, ensuring long-term maintenance-free operation.

Wireless Transmission Comparison and System Compatibility

GPRS transmission relies on mature mobile networks to directly upload pipeline pressure data to the cloud, supporting both local and remote IP configuration, suitable for projects with existing mobile network coverage. LoRa transmission works with gateways, offering ultra-low power consumption, long-distance communication, and strong signal penetration, supporting self-organizing networks, ideal for remote or complex terrains. NB-IoT adopts the latest narrowband technology, providing low cost, wide coverage, and large connection capacity, especially suitable for large-scale smart pipeline network deployments.

All three methods support standard MQTT or TCP protocols for seamless integration with mainstream SCADA, PLC, and cloud platforms, eliminating the need for additional wiring modifications.

Typical Application Scenarios

In the petrochemical industry, the transmitter is installed on reactors and pipelines to monitor pressure and temperature changes in real time, enabling process safety interlocks through high/low pressure alarms. In municipal water supply networks, devices are deployed in underground wells and transmit pressure data via NB-IoT or LoRa to dispatch centers, assisting in leakage analysis and pump optimization. In smart factories and energy management projects, GPRS is used to connect to enterprise MES systems, supporting remote parameter configuration and batch firmware upgrades.

Typical project cases include a large petrochemical base pipeline renovation project, where over 200 LoRa transmitters with self-organizing gateways achieved full-area monitoring, reducing annual maintenance costs by 45%. In another municipal water supply project, NB-IoT devices combined with cloud-based data analytics reduced pipeline leakage rates by 18%.

Selection Guide

Selection should prioritize evaluating network coverage conditions: NB-IoT is recommended for urban areas or regions with strong operator signals; LoRa is suitable for transmission distances exceeding 5 km or scenarios requiring self-networking; GPRS is ideal for projects with existing base station coverage. Explosion-proof environments require cast aluminum housing models, and corrosive media require verification of 304 stainless steel compatibility. Measurement range should cover 1.5 times the peak operating condition, and sampling frequency can be set between 1–60 seconds according to process response time.

For bulk procurement projects, antenna interfaces, battery capacity, and housing dimensions can be customized according to system protocol requirements.

Integration Considerations

Before installation, ensure thread compatibility between the fluid channel and the pressure sleeve, and confirm proper sealing of the stainless steel diaphragm. After powering the wireless module, parameter configuration must be completed, including server IP, upload frequency, and alarm thresholds. For battery-powered operation, it is recommended to configure sleep mode to extend service life. During system integration, standard protocol interfaces should be prioritized to avoid secondary development. In environments with strong electromagnetic interference, anti-interference film protection should be retained.

OEM Customization and Bulk Supply Advantages

Nexisense supports OEM branding and customization, including wireless protocols, display interfaces, connection specifications, and housing colors. Bulk supply offers flexible minimum order quantities, long-term price locking, and technical support packages, including interface documentation, SDK examples, and on-site commissioning guidance, enabling system integrators to respond quickly to project tenders.

Frequently Asked Questions

1. How does the transmitter ensure pressure measurement accuracy under large temperature fluctuations?

The product integrates a temperature compensation module and oil-filled pressure chamber. Real-time temperature data is used for linear correction, and combined with anti-vibration design, temperature drift is controlled within ±0.5% FS.

2. What are the differences between NB-IoT and LoRa in coverage and power consumption?

NB-IoT relies on operator base stations with lower single transmission power and wider coverage, suitable for urban networks. LoRa supports self-networking and longer distances, suitable for remote areas. Selection should be based on field signal testing.

3. Can the explosion-proof housing support long-term outdoor immersion?

The housing is rated IP66. Stainless steel connections support short-term immersion. Waterproof connectors are recommended for long-term use.
