Description
Duplex Thermocouple Probe with Connector (Model AKED-3×300) is a K Type duplex thermocouple engineered for continuous high-temperature measurement in industrial processes where equipment availability and process reliability are critical. The duplex construction incorporates two independent sensing junctions within a single SS310 sheath, allowing the secondary junction to be used when the primary junction reaches the end of its service life. This helps reduce unplanned shutdowns and maintenance interruptions.
Designed for temperatures up to 1200°C, the sensor features a 3 mm diameter SS310 stainless steel sheath that provides excellent resistance to oxidation and high-temperature environments. The probe is fitted with a Big Omega-type male-female connector, specifically sized to accommodate the additional conductors required for duplex thermocouples while providing quick installation and replacement.
The FG/FG/SS (Fiberglass insulated with Stainless Steel braided) cable protects against heat, abrasion, and mechanical wear, making the assembly suitable for demanding industrial environments. The connectorized design also simplifies maintenance by allowing rapid sensor replacement without rewiring the control system.
This Duplex Thermocouple Probe is widely used in industrial furnaces, kilns, heat treatment plants, boilers, power generation, steel manufacturing, glass production, cement plants, petrochemical facilities, and other continuous process industries where maintaining uninterrupted temperature monitoring is essential.
As a leading thermocouple manufacturer in India, Aavad Instrument Pvt. Ltd. manufactures customized duplex thermocouple probes with various sheath materials, insertion lengths, cable constructions, connector types, and thermocouple calibrations including K, J, T, and N to meet OEM and industrial process requirements.

FAQs
1. What is an RTD Washer Type Temperature Sensor?
An RTD Washer Type Temperature Sensor is a PT100 Resistance Temperature Detector (RTD) designed to measure surface temperature by mounting beneath a bolt or screw head. This design eliminates the need for a dedicated threaded or drilled sensor port while providing accurate and reliable temperature measurement.
2. Why use a Washer-Type RTD instead of an Insertion RTD?
A washer-type RTD is ideal when the temperature of a machine surface, motor housing, pipe flange, heat exchanger, or bolted component needs to be monitored without modifying the equipment. It offers simple installation, secure mounting, and accurate surface temperature measurement.
3. What Washer Sizes are available?
This RTD Washer Type Temperature Sensor is available in standard M6, M8, and M12 washer sizes, providing compatibility with a wide range of industrial machinery, electrical equipment, compressors, pumps, and OEM applications.
4. Where are RTD Washer Type Temperature Sensors commonly used?
RTD Washer Type Temperature Sensors are widely used in HVAC systems, refrigeration equipment, industrial machinery, pipelines, compressors, pumps, heat exchangers, electric motors, generators, transformers, and OEM equipment where accurate surface temperature monitoring is required.
