Product Overview
The WZPK-335U thin-film platinum RTD is a precision temperature sensor utilizing advanced thin-film platinum elements. Its compact diameter and flexible construction allow installation in confined spaces where traditional RTDs cannot fit. The sensing element is fabricated by sputtering platinum onto a ceramic substrate via laser technology, ensuring high stability and resistance to vibration. Encased in a stainless steel sheath with magnesium oxide insulation, it delivers robust performance even in harsh environments.
Key features include customizable mounting options (e.g., threaded couplings, flanges) and multiple outer diameters (φ3mm to φ12mm). With a broad operating range (-200℃ to +800℃) and rapid thermal response, it provides real-time temperature feedback for industrial automation. The low self-heating effect (≤0.3℃) minimizes measurement drift, making it ideal for continuous monitoring applications. Its modular design accommodates diverse industrial needs without compromising accuracy or durability.41419
