Reliable telemetry is the nervous system of modern automated facilities. In a world transitioning towards Edge Intelligence and high-density industrial server arrays, environmental fluctuation poses substantial financial risks.
Modern data infrastructures and industrial labs have shifted to high-density deployments. A fluctuation of 1°C or a 5% shift in relative humidity (RH) can trigger equipment failure, electrostatic discharges, or accelerate oxidation. Standard sensors fall short; robust DIN rail components are vital.
Seamless cross-platform operations rely on versatile data connectivity. Modern control boxes mandate DIN rail hardware supporting PoE (Power over Ethernet), standard TCP/IP, LoRa/LoRaWAN wireless links, and RS485 Modbus connectivity to build highly redundant data networks.
Single environmental metrics are no longer sufficient. Modern containment monitoring demands integrated detection systems measuring H₂S, SO₂, NO₂, TVOC, Ozone (O₃), Carbon Monoxide (CO), dew point, and atmospheric pressure alongside core humidity and temperature levels.
Explore our flagship high-performance DIN Rail and cabinet-oriented environmental telemetry units manufactured for high-reliability applications.
Established in 2007, Beijing Yingchuanglihe Electronic Technology Co., Ltd. is a high-tech pioneer integrating environmental sensor R&D, advanced chip calibration, and hardware manufacturing.
We build our modules using premium imported sensing elements from global industry leaders, specifically Sensirion (Switzerland) and Bosch (Germany). This delivers prolonged operational stability and prevents signal drift in hostile environments.
Enjoy hassle-free integration. APEM hardware natively supports industry standard communications: Modbus TCP/IP via RJ45, Modbus RTU via RS485, SNMP for IT systems, MQTT for direct cloud telemetry, and wireless systems like LoRaWAN.
Every single sensor batches leave our floor holding CE, FCC, and RoHS certificates. Further, we support comprehensive OEM/ODM custom branding, customized probe extensions up to 10 meters, and custom multi-gas boards.






Environmental parameters are heavily dictated by local topologies and operating conditions. From cold high-altitude transport lines to humid subterranean systems, see where our hardware performs.
Cooperating with COMLAB (Switzerland), our protection-class Ethernet environmental telemetry devices (like the TH-5869 series) are deployed directly in wayside cabins of major national lines including the Beijing-Kowloon Line, Beijing-Shanghai Line, and Wuhan-Guangzhou Line. They withstand massive vibration and EM interferences while continuously monitoring moisture infiltration.
Deployed extensively at Baidu's Yangquan Data Center, our next-generation APEM intelligent environmental gateways monitor rack microclimates. Supporting PoE, they connect directly to switchboards, enabling real-time hot-aisle/cold-aisle delta calculations and preventing condensate issues without extra power distribution cabling.
Installed inside high-level autonomous driving integrated roadside equipment boxes in Beijing's flagship pilot zones. The APEM series acts as an environmental safeguard for sensitive edge-computing GPU modules, preventing thermal throttle by triggering emergency ventilation fans via onboard relays.
Collaborating with Beijing Enterprises Water Group, we co-designed solutions for remote pump station protection and smart pipeline networks. These custom enclosures monitor dew point profiles to forecast pipeline condensation and protect high-voltage relays from structural corrosion.
With precise atmospheric pressure monitoring (such as our APEM-5930P models), laboratories prevent cross-contamination by maintaining pressure differentials between isolation rooms while logging temperature down to ±0.1°C accuracy.
Working in munitions depots and military archives where TVOC and Ozone are critical variables. High-sensitivity detection ensures static charge reduction and chemical stability of raw materials stored in sealed vaults.
Compare the design layout of different models within our DIN-rail mountable lineup. We provide choices across interfaces, parameter scopes, and external probe flexibility.

At Yingchuanglihe, we continually push sensing boundaries to accommodate future industrial telemetry needs.
Traditional electrochemical and polymer sensors suffer from accuracy drift over time. Our R&D division is finalizing auto-calibration algorithms integrated at the local MCU level, utilizing environmental historical curves to adjust baseline drift, cutting manual maintenance by 80%.
Following our joint venture development with the Beijing University of Civil Engineering and Architecture, we are weaving Beidou positioning and sub-nanosecond timing modules into environmental gateways for high-precision geo-deformation and outdoor utility cabinet mapping.
We are collaborating with semiconductor packaging centers to explore MEMS-level integrated multigas arrays. This will enable standard 35mm wide DIN rail housings to measure 10 parameters simultaneously with high accuracy.
Why do international integrators rely on Yingchuanglihe? Our strategic location and integrated industrial ecosystem in Beijing guarantee fast execution.
With five automated assembly lines, our manufacturing floor holds raw component reserves that protect clients from semiconductor shortage waves. We secure high-precision chips directly through long-term relationships with Switzerland and Germany.
We do not use generalized support call-centers. Any technical inquiry, protocol integration challenge, or customization request is forwarded directly to our engineering division in Beijing, ensuring a comprehensive solution response in under 8 hours.
Before batch release, every sensor undergoes aging runs in our microclimate test rooms. Transmitters are run through thermal shifts between -40°C and +85°C to verify stability against field condensation and tracking faults.
