Chongqing Chuanyi WZGPK-73DH-GB/1P2-AJ150G-M20XC6-AXX-I5/2AM20 Explosion-proof RTD
WZGPK-73DH-GB/1P2-AJ150G-M20XC6-AXX-I5/2AM20
The WZGPK is a heavy-duty explosion-proof armored Pt100 RTD temperature sensor engineered for accurate thermal monitoring in hazardous industrial environments. Equipped with a high-precision Class A platinum sensing element, a 3-wire connection, a 6mm diameter sheath made of durable 321 stainless steel, and a 150mm insertion length, this flameproof sensor delivers exceptionally fast thermal response, vibration resistance, and long-term stability across a wide temperature range from -200°C to 600°C. Designed with an M20x1.5 process thread and an explosion-proof junction box, it provides reliable flameproof protection and continuous signal accuracy for chemical plants, oil refineries, and automated process control systems.
The WZGPK series explosion-proof armored platinum resistance temperature detector represents high-performance temperature sensing technology tailored for demanding process automation environments. Built using advanced mineral-insulated mineral sheath technology, this RTD probe embeds a high-purity platinum element inside compacted magnesium oxide powder protected by a rugged 321 stainless steel outer tube. This compact armored design endures extreme mechanical shock, high pressure, and intense structural vibration while facilitating rapid heat absorption and quick response times.

The heavy-duty flameproof junction box effectively contains potential electrical sparks inside the housing, ensuring safe continuous operation in combustible gas or vapor environments. Featuring a precision M20x1.5 mounting thread and a 150mm probe depth, this sensor integrates easily into narrow pipelines, pressure vessels, and reaction tanks. Fully compliant with IEC 60751 global standards, it provides linear resistance output to PLCs, transmitters, and temperature controllers, making it an essential solution for industrial process safety.

FAQ
Q: How does the explosion-proof enclosure protect hazardous workplaces?
A: The flameproof junction box and sealed entry threads are engineered to withstand internal pressure during an electrical spark, preventing flame or heat from escaping into explosive ambient gases. Q: Why choose a 3-wire Pt100 configuration over a 2-wire setup?
A: A 3-wire circuit automatically compensates for lead wire resistance, eliminating measurement errors over long wire runs and ensuring superior temperature accuracy in automated control systems. Q: Can the insertion length or process thread be customized for custom equipment?
A: Yes, as an industrial instrumentation manufacturer, we offer full OEM customization including tailored insertion depths ($l$), sheath diameters, thread types (such as NPT, G, or metric), and upgraded sheath alloys like 316L stainless steel. Q: Is this temperature probe compliant with international quality standards?
A: Yes, the WZGPK series is manufactured in strict compliance with IEC 60751:2022 and GB/T30121-2013 standards, ensuring precise calibration and seamless international system compatibility.
