Founded in 2007, Beijing Yingchuanglihe (YCLI) is an elite global manufacturer of advanced industrial-grade climate sensors. Operating from our state-of-the-art 1,500m² manufacturing plant, we run five automated production lines to deliver high-precision, low-drift environmental instrumentation. Trusted by high-tech giants, and fully compliant with CE, FCC, and RoHS parameters.
By integrating imported capacitive polymers and micro-machined components, YCLI ensures ultra-long-term stability with minimal annual measurement drift.
Full native support for global networking systems. Real-time integration is simplified via SNMP, Modbus RTU/TCP, MQTT, and wired/wireless dual topologies.
Every transmitter undergoes dynamic humidity chamber runs. Our specialized engineering division answers all technical inquiries with exhaustive schematics within 8 hours.
Industrial hygrometry demands far more than basic comfort-level measuring. It requires robust material selection, advanced electronics, and sophisticated mathematical calculations. At YCLI, our industrial hygrometer transmitters are meticulously designed to handle aggressive industrial gases, severe temperatures, and rapid dynamic pressure shifts.
At the physical detection level, YCLI transmitters utilize precision thin-film capacitive sensor elements. The dielectric layer consists of a specialized hygroscopic polymer that absorbs or releases water vapor in proportional balance with the surrounding ambient atmosphere.
This absorption changes the overall capacitance of the micro-structure, which is then captured by an ultra-stable analog-to-digital converter. By integrating temperature measurement on the same monolithic chip die, we achieve automatic real-time temperature compensation. This calculation eliminates thermal-induced reading shift—a common failure mode in lower-grade transmitter products.
Relative humidity (RH) is highly dependent on ambient temperature. To provide engineers with a stable physical variable, YCLI transmitters contain embedded processors running the Arden Buck equations. This calculation yields the exact, real-time dew point temperature. Consequently, changes in air pressure or temperature do not skew the baseline moisture reading, making our transmitters ideal for compressed air systems and industrial drying cabinets.
Developed the industry's first intelligent environmental terminal operating on the native TCP/IP protocol. In 2009, we collaborated with Switzerland's COMLAB to protect critical networking on Beijing-Kowloon and Beijing-Shanghai high-speed rail lines, establishing our design standard for extreme mechanical vibrations.
Pioneered industrial PoE integration alongside Taiwan's Foxconn and Founder Technology. Scaled our platform to monitor environmental parameters in complex computing clusters, culminating in standard environmental sensor deployments at Baidu’s massive Yangquan Data Center.
Partnered with Beijing Enterprises Water Group and Beijing University of Civil Engineering and Architecture. Merged precision atmospheric profiling with Beidou high-precision deformation data and edge computing gateways for autonomous road testing box systems, securing high-speed data transmission under harsh outdoor conditions.
From heavy manufacturing to complex IT infrastructure, environmental stability is a primary driver of process control. Here is how YCLI's CE-certified transmitters solve actual industry pain points.
High relative humidity can trigger trace-level galvanic corrosion on motherboards, while low humidity promotes electrostatic discharge (ESD). YCLI’s PoE transmitters seamlessly interface with Data Center Infrastructure Management (DCIM) tools via SNMP to ensure steady climate control.
Pharmaceutical processes require strict containment and contamination controls. The APEM-5930P monitors atmospheric pressure differences between processing halls and airlocks, preventing air contaminants from migrating into sterile formulation zones.
In municipal drainage and chemical transmission lines, humidity and hazardous gases threaten worker safety and asset integrity. Working alongside Beijing Enterprises Water Group, YCLI has engineered robust monitoring gateways capable of standing up to constant moisture exposure.
YCLI operates from Beijing, the heart of China’s advanced electronics cluster. Our manufacturing setup leverages advanced assembly techniques and strict quality controls to give global enterprise buyers a distinct competitive edge.
By running 5 automated, cleanroom-standard assembly and testing lines, we can scale production volumes without compromising sensor accuracy. Key production processes—such as trace solder deposition and chip inspection—are handled by precise pick-and-place automated systems.
This automated approach guarantees that every single batch of industrial transmitters shows highly repeatable performance, keeping calibration curves identical across massive system deployments.
At YCLI, we do not perform simple sample-based quality inspections. Every single transmitter is run through temperature and humidity cycles in our calibration chambers.
We measure sensor response across different calibration plateaus. This step validates both temperature-compensation logic and high-humidity recoverability before units are boxed and prepared for shipment.
For procurement managers and system integrators worldwide, sensor compatibility and long-term durability are paramount. YCLI has developed a streamlined OEM/ODM customization pipeline designed to satisfy strict performance specifications.
Our engineering division can quickly customize transmitter firmware to match existing industrial systems. Whether your environment runs on Modbus (RTU or TCP), custom SNMP tables, or lightweight MQTT payloads for cloud engines, we can compile a firmware package specifically for your hardware configuration.
Standard transmitter bodies often cannot fit into specialized process plumbing. YCLI can customize sensor probe bodies using AISI 316L stainless steel, design custom flange mounts, adjust sintered metal filter porosities, or provide high-pressure Teflon cable glands for vacuum chambers.
Deploying instrumentation in international facilities requires absolute alignment with regulatory standards. YCLI transmitters are designed, tested, and fully certified to comply with strict global safety and environmental laws.
Our industrial hygrometer transmitters carry complete CE, FCC, and RoHS certifications. This verified status confirms that our electronics successfully manage electromagnetic interference (EMI) and electro-static hazards, allowing for direct installation in demanding environments without violating regional safety rules.
Every sensor suffers from drift over years of use in harsh conditions. YCLI builds stable analog-to-digital frontends and provides simple digital offset calibration interfaces. This design lets technicians perform on-site, single-point offset adjustments over Modbus or Ethernet, avoiding the need for expensive and slow physical sensor replacement.
