Product Introduction
The WZPK-134U Thin-Film Platinum RTD is a precision temperature sensor designed for industrial automation, environmental monitoring, and medical equipment. Its core sensing element combines ceramic substrate with platinum film via advanced laser sputtering technology, enabling stable performance and fast response within a range of -200°C to +800°C. The compact and flexible design allows installation in confined or high-vibration spaces where traditional RTDs are unsuitable.
Key Features
Stainless steel sheath and magnesium oxide insulation ensure resistance to contamination and mechanical stress. The laser-trimmed platinum film achieves minimal deviation in temperature coefficient (α=0.003851±0.000006) and rapid thermal response (T0.5≤0.3s). Options for gold-plated nickel or pure palladium leads enhance signal reliability. Insulation resistance exceeds 100MΩ at 15-35°C, with low self-heating effect (≤0.3°C).
Applications
Ideal for temperature monitoring in petrochemicals, power plants, and food processing. Its robust construction suits automotive systems (e.g., engine oil temperature) and medical device controls, while the anti-vibration design benefits environmental gas emission analysis.
Advantages
- Accuracy: Linear output minimizes dynamic errors.
- Durability: Stainless steel and ceramic layers improve pressure resistance.
- Adaptability: Supports flange, threaded, or non-fixed installations.
