In the context of Industry 4.0 and digital transformation, real-time, accurate, and low-power remote pressure monitoring has become a core requirement for process industries and public utilities. Traditional wired deployment not only faces high cabling costs but also shows insufficient flexibility in complex and dispersed working conditions. The YD-221W1 wireless pressure transmitter developed by Nexisense, with its integrated low-power NB-IoT communication technology, excellent anti-interference capability, and wide range covering 0-250MPa, provides system integrators and engineering contractors with a highly reliable edge sensing solution.

Hard Requirements for Wireless Pressure Sensing in Industrial Scenarios

For engineering contractors and project leaders, on-site sensors are not only data collection probes but also the most fundamental "stable cornerstone" in the entire IoT topology. Industrial scenarios are usually accompanied by extreme temperatures, electromagnetic interference, flammable and explosive environments, and geographical restrictions that make wiring inconvenient.

The original design intention of YD-221W1 is to solve the dual pain points of "difficult data transmission" and "difficult on-site power supply" in remote high-pressure monitoring. By integrating multiple wireless communication protocols (NB-IoT, LoRa, 4G, GPRS), Nexisense provides diversified choices for network coverage of different complexity levels.

The housing has excellent sealing performance, with an operating temperature range spanning -20°C to 70°C, and storage temperature extending to -30°C to 80°C. In addition, the device complies with GB/T 17626.2/4-2006 electromagnetic compatibility standards, and its anti-vibration performance meets the IEC 60068-2-6 standard, ensuring that data is not lost or drifted in heavy equipment vibration environments.

System Integration Perspective: Application Scenario Topology of YD-221W1

Smart Water Utilities and Municipal Pipe Networks

In the monitoring of urban water supply and drainage pipe networks, because the monitoring points are extremely dispersed and mostly located underground or outdoors, traditional wired cabling is almost impossible to implement. YD-221W1 utilizes the high penetration of NB-IoT signals to easily penetrate manhole covers and underground facilities, uploading pipe network pressure to the monitoring platform in real time, realizing pipe burst warning and energy efficiency optimization.

Petroleum, Petrochemical and Storage & Transportation Monitoring

For pressure monitoring at oil and gas wellheads and oil pipelines, explosion-proof performance is the primary criterion. Nexisense's wireless solution avoids the risk of on-site hot work cabling, and wirelessly aggregates gauge pressure and absolute pressure data from each node to the central control room, significantly reducing the construction period and initial investment of engineering projects.

Hydraulic Systems and High-pressure Test Benches

In ultra-high pressure applications such as 250MPa, the long-term stability of the sensor core is crucial. The thin-film sputtering technology used in YD-221W1 can effectively cope with the impact of pressure transients. Combined with its low-power LCD display, on-site technicians can perform real-time numerical calibration and status inspection.

Q6: In high-pressure customization (above 200MPa), how is the sensor's nonlinearity error and hysteresis controlled?

A: In the ultra-high pressure range, we use high-range strain cores or thin-film sputtering technology, supplemented by full-temperature range linear compensation algorithms. Each high-pressure customized product undergoes strict step-by-step pressure calibration to control nonlinearity error and hysteresis within the set accuracy range (such as 0.25%FS), ensuring linearity across the full range.

Q7: How to deal with battery activity decline caused by severe winter cold, which in turn causes wireless transmission failure?

A: YD-221W1 uses industrial-grade wide-temperature lithium thionyl chloride batteries, whose discharge curve is superior to ordinary lithium batteries in low-temperature environments. At the same time, the device supports an operating environment of -20°C to 70°C.
