YDW37 Wireless pressure transmitter

Precise sensing · Wireless freedom · The revolutionary power of industrial IoT

The wireless pressure transmitter employs high-precision silicon piezoresistive/ceramic capacitive principles, integrated with industrial-grade low-power wide-area network technology (LoRaWAN/NB-IoT/4G), enabling precise measurement and remote wireless transmission of process pressure. Powered by an internal high-performance lithium battery, it completely eliminates the need for power cables and signal cables. Combined with IP67/68-rated protection and intrinsically safe design, it offers a modern solution for equipment condition monitoring, energy management, and process control that is extremely easy to deploy, cost-effective, and efficient to maintain.

Product Advantages
1. Ultra-simple deployment, significant cost savings: Save over 90% on cable, conduit, and installation costs. No need to shut down power or production; installation can be completed in minutes, with deployment efficiency improved by 10 times.
2. Ultra-low power consumption, long-lasting battery life: Featuring low-power design and high-performance lithium batteries, battery life can reach 5–10 years* under typical operating conditions, truly achieving “install and forget.”
3. Safe and reliable, suitable for harsh environments: Features IP67/68 high protection ratings and ATEX/Ex ia/ib explosion-proof certifications, capable of withstanding outdoor, humid, and flammable/explosive environments.
4. Smart connectivity, efficient maintenance: Data is transmitted directly to the cloud platform or SCADA system via a wireless gateway, supporting remote configuration, diagnosis, and alarms, enabling predictive maintenance and reducing on-site inspections.
5. Flexible scalability, seamless integration: Using standard communication protocols (such as MQTT, HTTP), it can seamlessly integrate into existing IoT ecosystems and easily cover remote measurement points where wired deployment is challenging.

Core Application Areas
✅ Predictive Maintenance for Equipment: Pressure trend monitoring for critical equipment such as compressors, pumps, and hydraulic systems, with early warning of potential failures.
✅ Energy and Utilities: Pressure monitoring for water supply/heating networks, remote monitoring of fire hydrant water pressure, and safety monitoring of natural gas pressure regulation boxes.
✅ Process Industry Monitoring Points: Pressure monitoring of dispersed raw material tanks and intermediate tanks, replacing costly wired upgrades.
✅ Environmental Protection and Smart Agriculture: Data collection of air pressure and water pressure at environmental monitoring stations, pressure control of pump rooms in smart irrigation systems.
✅ Mobile Equipment and Test Benches: Pressure measurement of construction machinery, test vehicles, and temporary test pipelines, without the constraints of wiring.
