Why choose a Duplex RTD PT100 sensor with a 2400mm insertion length instead of a standard simplex RTD for deep-tank or long-column temperature monitoring?
Because a single sensor failure on a critical measurement point can halt a production line, the Duplex RTD PT100 Sensor 6x2400D is engineered with two fully independent 3-wire PT100 circuits inside a single SS316 sheath, giving plants built-in redundancy at a transparent, factory-direct price with zero middleman markup and ready stock for immediate nationwide dispatch. This configuration is purpose-built for deep vessels, long pipeline runs, tall reactors, and large storage tanks where a shorter probe cannot physically reach the true process temperature zone, and where a second backup element removes the need for a process shutdown just to replace a failed sensing circuit.
Each unit is manufactured to a -50°C to 400°C working range with Class A accuracy, meaning the resistance-versus-temperature curve stays tight and repeatable across demanding thermal cycles — critical for process control loops, batch reactors, and continuous monitoring systems where drift is not acceptable. The 6mm OD probe is built from SS316 for corrosion resistance against most process chemicals, steam, and humid atmospheres, and it is packed with compacted magnesium oxide (MgO) insulation, which improves thermal response time while protecting the internal element from vibration and mechanical shock. The die-cast aluminum protection head carries an IP67 rating with a threaded cap and safety chain, keeping the termination compartment sealed against dust ingress and washdown moisture, while the double cable entry (1/2″ NPT F) supports clean, organized duplex wiring straight into your junction box or transmitter. This sensor is manufactured by Aavad Instrument Pvt. Ltd., whose facility operates under ISO 9001:2015 certified manufacturing practices and produces CE-marked sensors that meet applicable EU safety, health, and environmental protection requirements, giving plant engineers documented quality assurance behind every unit shipped.

FAQs
1. What does “duplex” mean in a duplex RTD sensor, and why would I need it?Duplex means the sensor contains two completely independent PT100 measurement elements, with each element having its own 3-wire circuit, installed inside a single probe sheath. This built-in redundancy allows you to obtain dual temperature readings, perform cross-verification, operate redundant control loops, or maintain a backup measurement circuit if one element or circuit develops a fault over time. It can also reduce the need to remove the sensor from the process just to access a secondary measurement element.
2. Can this 2400mm RTD be cut or shortened to fit my application?
No. The 2400mm insertion length is factory-defined to maintain the sensor’s specified measurement performance and mechanical integrity. If you require a different insertion length, contact the Buyinstrument.shop team before ordering. Multiple length variants may be available, and our team can help identify the appropriate sensor configuration for your vessel, tank, column, or pipeline depth.
3. Is this sensor suitable for outdoor or humid plant environments?
Yes. The sensor features an IP67-rated die-cast aluminum head with a threaded cap and chain, helping protect the terminal compartment against dust and temporary water exposure. This construction makes the duplex RTD suitable for indoor process areas, humid industrial environments, and suitable semi-exposed outdoor installations when installed according to the application’s environmental requirements.
4. Why should I buy this from Buyinstrument.shop instead of elsewhere?
