RTD90- A Remote Mount Industrial Resistance Temperature Detector is a temperature-sensing device designed for applications where the sensing element needs to be installed at a distance from the measuring or control system. It allows for flexible installation and helps protect sensitive electronics from harsh environments.
Key Features:-
- Uses connection head to protect the electrical connections from environmental factors such as moisture, dust, and mechanical damage.
- Connection head usually made of aluminum, stainless steel or plastic and available in weatherproof,
explosion-proof or corrosion-resistant designs. - Connection head contains terminals or 4-20mA output temperature transmitter for signal conditioning.
- Available with Pt100 or Pt1000 elements per IEC 60751 standard in Class A or Class B accuracy ratings.
- Available in 2-wire, 3-wire, or 4-wire configurations for enhanced accuracy and reduced lead wire resistance errors.
- Available in 304, 316, or 316L stainless steel for corrosion resistance and sheath diameters range from 3mm to 12mm (custom sizes available).

Application Note
Temperature monitoring plays a critical role in various industrial sectors, ensuring optimal performance, safety, and efficiency. In power plants, it is essential to monitor the temperature of boilers and turbines to prevent overheating and maintain safe operating conditions. Similarly, in chemical, petrochemical, and process plants, reactor and process temperature control are crucial for maintaining chemical reactions at their desired rates and ensuring product quality. In metallurgy and steel plants, accurate furnace and molten metal temperature sensing is key to preventing damage to equipment and ensuring the proper forging and casting of metals. Additionally, in the food and pharmaceutical industries, hygienic temperature monitoring ensures that processes adhere to strict safety and quality standards, avoiding contamination or spoilage. Lastly, in oil and gas refineries, monitoring the temperature of pipes, tubes, fan bearings, and pumps is vital to prevent equipment failure, improve operational efficiency, and safeguard personnel. In all these sectors, precise temperature control and monitoring are fundamental for maintaining safety, quality, and productivity.
