In deep industrial storage tanks, chemical reactors, and distillation vessels, a temperature sensor failure can interrupt temperature monitoring and affect production operations. The Duplex Pt100 RTD Sensor (6mm × 2400mm) provides two independent temperature measurement circuits within a single process entry, making it suitable for applications where measurement redundancy is important.
This duplex Pt100 RTD sensor incorporates two electrically isolated Class A Pt100 platinum circuits within a continuous SS316 stainless steel sheath. Each measurement circuit is designed for accurate industrial temperature measurement according to the specified sensor configuration and DIN EN 60751 requirements.
The 2400mm immersion length provides extended measurement reach for deep tanks, vessels, and process equipment. The long SS316 probe is designed to position the sensing elements deeper into the process medium, helping obtain representative temperature measurements where temperature stratification may occur.
The probe construction uses compacted Magnesium Oxide (MgO) insulation to provide electrical insulation and mechanical support for the internal RTD elements. The specified insulation resistance is greater than 100 MΩ at 500V DC.
The sensor is terminated with an IP67 die-cast aluminum flameproof enclosure designed for industrial and hazardous-area instrumentation applications. The flameproof head provides protection for the internal electrical termination while the enclosure’s cable-entry arrangement allows the two measurement circuits to be integrated into separate instrumentation systems where required.
The dual 3-wire configuration allows the primary and secondary Pt100 circuits to be connected independently. For example, one circuit can be connected to a plant control or monitoring system while the second circuit can be used for an independent display, monitoring channel, or backup measurement system, subject to the requirements of the installation.
The fixed 1/2″ BSP (M) process connection provides a direct process mounting arrangement. The extended 6mm diameter SS316 sheath and fixed construction make this configuration suitable for deep industrial tanks and process vessels where a long insertion length is required.
For buyers looking for a duplex Pt100 RTD sensor flameproof configuration with a 2400mm insertion length, this model provides a practical combination of dual temperature measurement, extended probe reach, and industrial enclosure protection.
