We specialize in ODM/OEM services for infrared thermal imaging solutions, including handheld thermal imagers, smartphone-connected thermal cameras, thermal analyzers, and thermal imaging telescopes. Our products serve global customers in power inspection, building diagnostics, firefighting, industrial maintenance, and outdoor applications.
A deep technical perspective on next-generation radiometric sensing, uncooled microbolometer advancements, edge-AI analytics, and multispectral sensor fusion.
The industrial thermal imaging landscape is shifting rapidly from 17μm to 12μm and sub-10μm pixel pitch detector arrays. By reducing the physical pitch of uncooled Vanadium Oxide (VOx) and Silicon Microbolometers, sensor payloads achieve dramatic optical miniaturization while maintaining high spatial resolution.
Dianyang’s engineering roadmap integrates state-of-the-art VOx sensors that deliver lower thermal time constants and higher thermal sensitivity (NETD < 30mK to 40mK). This reduction in pixel pitch allows compact industrial optics to capture fine thermal gradients at long distances without sacrificing frame rates or sensor lifespan.
Traditional thermal imaging relied solely on human interpretation of raw color palettes (Ironbow, Rainbow, Black Hot). Modern Industry 4.0 paradigms demand autonomous intelligence directly on the edge sensor.
Our upcoming thermal architecture embeds hardware-accelerated Convolutional Neural Networks (CNNs) directly into handheld and fixed-mount thermal cameras. These algorithms perform real-time pattern recognition, isolating phase unbalance in high-voltage transformers, localized PCB trace overheating, and insulation breaks dynamically, reducing false alarms by over 87%.
Combining LWIR (Long-Wave Infrared, 8–14 μm) with visible spectrum imagery via Dual-Spectrum Fusion allows technicians to overlay thermal radiometric data onto structural edges. Dianyang's spatial alignment algorithms dynamically correlate optical and infrared pixels across varying target distances, ensuring zero parallax error during detailed maintenance inspections.
Noise Equivalent Temperature Difference (NETD) defines the minimum temperature variation the sensor can resolve. A lower NETD (<30mK) guarantees sharp image clarity even under low thermal contrast conditions. Combined with wide calibration bands (up to 1200°C), Dianyang sensors maintain non-linear calibration accuracy across demanding metallurgical, petrochemical, and automotive power electronics environments.

Deploying tailored thermal measurement tech across complex global industries to eliminate unscheduled downtime and improve operational efficiency.
Overheated switchgears, loose busbar clamps, and degraded transformer insulators represent catastrophic points of failure in electrical transmission grids. Radiometric cameras like the DP-38D enable utility engineers to inspect high-voltage assets from safe standoff distances. Real-time isotherm alerts pinpoint phase-to-phase imbalances before thermal runaways cause regional blackouts.
Thermal bridging, moisture ingress under flat roofs, and insulation degradation lead to millions of dollars in wasted heating and cooling energy annually. By utilizing high-sensitivity thermal imagers, building certifiers map thermal losses instantly. Advanced software packages calculate temperature deltas across wall envelopes, proving compliance with international green building standards (LEED, BREEAM).
As microelectronics increase power density, thermal dissipation becomes the main bottleneck in hardware reliability. Dianyang’s benchtop PCB Thermal Analyzers provide non-contact, high-spatial-resolution heat mapping across surface-mount components, ICs, and power MOSFETs. R&D engineers can isolate short circuits, trace current concentration, and evaluate heatsink performance during design prototyping.
Leveraging state-of-the-art production systems, scalable component sourcing, and Design for Manufacturing (DFM) engineering.
Our dedicated engineering team applies Design for Manufacturing (DFM), Design for Testability (DFT), thermal simulation, and EMC pre-compliance analysis to optimize performance and accelerate development. We also support clients in obtaining key certifications such as CE, FCC, RoHS, REACH, CB, UKCA, KC, and PSE.
By operating under the corporate umbrella of publicly listed VHD (Shenzhen Stock Exchange), Dianyang implements high-precision Surface Mount Technology (SMT) automation, optical blackbody temperature calibration tunnels, and environmental stress screening (ESS) chambers.

All Dianyang thermal imagers and sensor core modules undergo strict laboratory validation. We provide full compliance documentation for international market entry, including:
We empower industrial brand partners and distributors by providing comprehensive white-label customization across hardware, firmware, and software:
Understanding Total Cost of Ownership (TCO), volume pricing tiers, and direct factory procurement advantages.
When procuring industrial thermal imaging hardware, enterprise buyers must balance upfront unit cost against long-term sensor reliability, optical calibration stability, and technical support access. Traditional Western brands carry heavy marketing overheads, elevating unit costs without offering additional measurement precision.
Dianyang delivers direct factory-to-enterprise pricing. By controlling raw VOx sensor integration, optical assembly, and software development under one roof, we offer up to 40% cost efficiency over equivalent resolution competitors while maintaining standard temperature accuracy within ±2°C or ±2%.
We support distributors, OEM system integrators, and industrial procurement departments with tiered volume quotes:
Technical guidance and answers to common procurement, calibration, and operational queries.
Vanadium Oxide (VOx) sensors provide superior thermal sensitivity (lower NETD) and higher temperature stability compared to Amorphous Silicon (a-Si) sensors. This allows VOx cameras to capture sharper images with clearer contrast under micro-temperature variations, making them ideal for high-precision industrial and diagnostic tasks.
For standard industrial preventive maintenance, annual re-calibration (every 12 months) is recommended. Dianyang thermal imagers feature self-calibrating internal shutters that adjust for ambient temperature drift during active field inspections, ensuring sustained measurement integrity between formal calibration cycles.
