PRODUCT DATA SHEET
LCH Integrated ER Corrosion & Ambient TH Sensor Module
Real-Time Micro-Environmental Diagnostics and Thin-Film Electrical Resistance Telemetry
1. Product Description
The LCH Integrated ER Corrosion & Ambient TH (Temperature/Humidity) Sensor Module is an edge-computing diagnostic device engineered to capture environmental risk factors and material degradation under insulation layers or within corrosive atmospheric zones.
The system unifies a high-contrast localized OLED user interface, precise environmental sensing elements, and a sacrificial dual-track plug-and-play probe. By recording real-time electrical resistance changes across fine sacrificial tracks against a hermetically shielded baseline, the transmitter calculates nanometer-scale thickness loss while automatically compensating for thermal resistance fluctuations.

3. Localized Telemetry Interface Decoding
The device is equipped with a crisp, high-visibility digital dashboard for rapid field walk-through inspections:
| Parameter Indicator | Sample Reading | Engineering Functional Meaning |
|---|---|---|
| T: | 32.5C |
Localized ambient/under-insulation temperature for real-time tracking and automatic thermal compensation calculation. |
| H: | 52.1% |
Relative micro-environmental humidity; functions as an early-warning predictor for fluidic ingress or insulation wetness. |
| CR: | 0.000 mm/y |
Annualized material corrosion rate derived from active track resistance drift (\(PCB\_R - R_0\)). |
| Rate: | 0.0 % |
Accumulated thickness loss rate of the sacrificial tracking grid. |
| P: | OK |
Power loop, reference electrode baseline, and communication hardware status verified as healthy. |
| Life: | 100% |
Sensor Remaining Useful Life (RUL) percentage gauge; guides predictive maintenance intervals before a probe swap is mandatory. |
4. Advanced Process Synergy: CUI Active Defense
When deployed in severe environments such as pipeline loops, chemical towers, and equipment nozzles, the module forms a powerful defensive closed loop alongside LCH active components:
- Water-Tight Layering: The curved process substrate is wrapped tightly with VCI silicone autolysis tape (50% wrap overlap profile) to establish an immediate physical water boundary and continuous vapor-phase passivation.
- Nanometer-Scale Tracking: The ultra-thin flexible electrode grid (0.02mm to 0.3mm) tracks material erosion metrics invisibly beneath the jacket padding without causing air gaps or insulation deformation.
- Active Purging: If humidity spikes are logged on the display screen or remote web console, operators activate the VCI POWER manifold to push low-pressure dry air or N₂ through the padding, venting trapped water out via the snap-fit silicone one-way drain plugs.
