(RT01) Single and Duplex Element RTDs (with Extension Lead Wire)

(RT02) Single and Duplex Element RTDs (with Sheath Terminations)

The RTD elements illustrated and described on the RTD catalog pages are designed to measure temperature in a variety of process and laboratory applications. These RTDs are specifically designed for use in two different process temperature ranges and will provide accurate and repeatable temperature measurement across a broad range. Low-range RTDs are constructed using fluoropolymer-insulated, silver-plated copper internal leads with potting compounds to resist moisture penetration. High-range RTDs are constructed with nickel internal leads inside swaged MgO-insulated cable to allow higher temperature measurements at the RTD element and provide higher temperature lead protection along the sheath.  From the catalog pages, you can select a variety of standard element materials, tolerances, sheath diameters, mounting fittings and terminations. Custom-built assemblies with non-standard specifications are available upon request.

(RT03) Water-Tight RTD Assemblies w/Optional Series 450 Temperature Transmitters

These RTD Assemblies house an optional Series 450 Temperature Transmitter (no connection head is required) that is ideal for monitoring temperature in small areas such as tanks and pipes. The water-tight construction meets the NEMA 6P, IP68 Protection Rating requirements. Standard units include a sensor, an M12 process connection housing, and an optional transmitter. The transmitter is a 2-wire unit with an analog output. It has measurement input for Pt100 resistance thermometers (RTD) in 4-wire connections. Transmitters can range from (-51 to 160) ºC [-60 to 320] ºF. With a 10 ºC [18 ºF] minimum span requirement. The ambient temperature limits for the M12 connector are (-40 to 85) ºC. 

(RT04) M12 Molded and Field Wireable Cables

M12 Molded and Field-Wireable cables are available for connection to Pyromation Water-Tight Assemblies with Optional Series 450 Transmitters. The M12 quick disconnect plug eliminates all external screw connections, simplifying the electrical installation process and solving the problems caused by moisture, loose connections, and corrosion. They are easier to install and more secure than conventional field-wired connections. Both are available in 2-, 3-, and 4-wire connection options and in straight or 90º angle styles. Molded cables are PVC insulated and meet NEMA 1, 3, 4, 6P, and IEC IP68. Field-Wireable Cable insulations are listed below and meet IP67 requirements. Cable lengths are manufactured to customer specifications. All M12 Molded Cables are supplied as 4-wire and are terminated as specified in the part number.
