RTD Element with Aluminum Head for Thermowell, 6in Long

RTD Element for Thermowell – 100 Ohm, 1/4" OD Sheath, 6" Long, 1/2" NPT SS Hex Fitting, Aluminum Head and Block

Resistance Temperature Detectors (RTDs) are precision temperature sensors designed to provide accurate and reliable temperature measurements across various industrial applications. These sensors are known for their high repeatability, interchangeability, and stability over time, making them an essential component in process control and monitoring systems.

This RTD element features:

• 100 Ohm Platinum Resistance: The industry standard for accurate and consistent temperature measurement.
• 1/4" OD Stainless Steel Sheath: Provides robust protection for the sensing element, ensuring durability in demanding environments.
• 6" Length: Designed to fit standard thermowell configurations for a wide range of applications.
• 1/2" NPT Stainless Steel Hex Fitting: Ensures secure installation and compatibility with threaded process connections.
• Aluminum Connection Head and Block: Lightweight and corrosion-resistant for added durability in industrial settings.

How RTDs Work: RTDs, also known as resistance thermometers, operate by utilizing the predictable change in resistance of metallic elements with temperature. A small excitation current passes through the RTD element, and the resulting voltage drop (proportional to resistance) is measured and converted into temperature readings. This ensures high accuracy and reliability in temperature monitoring. RTDs are available in two primary types:

• Wire-wound elements: Feature a fine platinum wire wound around a ceramic or glass core for precise sensing.
• Thin-film elements: Use a thin layer of platinum deposited on a ceramic substrate for compact designs.

Lead Wire Compensation: Because RTDs typically have a low initial resistance (often 100 Ohms) and a small resistance change per degree of temperature, lead wire resistance can significantly affect measurements. To maintain accuracy, this RTD supports 3-wire or 4-wire configurations, which compensate for lead wire resistance and ensure precise readings over long cable runs.

Wide Operating Range: With proper sheathing and configuration, RTDs can operate in extreme conditions, covering a temperature range of -200 °C to 600 °C (-328 °F to 1112 °F). This makes them suitable for applications in industries such as chemical processing, pharmaceuticals, food and beverage, oil and gas, and HVAC.
