Duplex RTD PT100 sensor with 4 inch probe

Heavy-Duty Duplex PT100 RTD Sensor – 6-Wire, 10mm x 4" SS Probe with 

Product Description

Engineered for mission-critical industrial applications where sensor failure is not an option, this heavy-duty Duplex PT100 RTD provides ultimate reliability and built-in redundancy. Housing two independent high-purity platinum elements within a single, ultra-rugged 10mm stainless steel probe, this sensor ensures continuous, highly accurate temperature data even if one element fails. The robust 4-inch (approx. 100mm) insertion length a process connection allow for secure, direct mounting into high-pressure pipelines, heavy process tanks, and demanding automated systems.

Technical Specifications

• Sensor Type: Duplex RTD PT100 (Dual Independent Platinum Elements)

• Wiring Configuration: 6-Wire System (Two standard 3-wire configurations for independent lead resistance compensation)

• Probe Dimensions: 10mm (Outer Diameter) x 4 Inches (Length / approx. 100mm)

• Process Connection: None

• Material Construction: Premium Stainless Steel (SS-304 / SS-316) for high corrosion and pressure resistance.

• Accuracy: Standard Class B (Class A available for high-precision requirements).

• Operating Profile: Designed for high mechanical stress, rapid flow rates, and continuous processing environments.

Key Features

• Built-in Redundancy (Fail-Safe): The duplex (dual-element) design allows you to connect one sensor to your primary PID controller or PLC, and the second to a backup system or local digital display, ensuring zero downtime if a primary loop fails.

• Ultra-Thick 10mm Probe: Unlike standard 6mm probes, this heavy-duty 10mm stem is built to withstand high-velocity fluid flow, heavy vibration, and extreme mechanical pressure without bending or snapping.

• 6-Wire Accuracy: Features two fully independent 3-wire circuits, guaranteeing high-accuracy thermal readings by fully compensating for lead-wire resistance over long distances.

Common Applications

• High-Pressure Fluid Dynamics: Ideal for deep insertion into main water, oil, or chemical pipelines where thick probes are required to resist flow-induced bending.

• Critical Process Heating: Mandatory for large-scale industrial boilers, furnaces, and reactors where continuous temperature monitoring is required for safety and compliance.

• Heavy Manufacturing: Perfectly suited for paper mills, metal processing plants, and foundries requiring ruggedized components.

• Power Generation & Turbines: Provides the fail-safe redundancy required for bearing, coolant, and exhaust temperature monitoring.
