Description
Duplex PT100 RTD Sensor (Model APED-5×100) is engineered for food processing, pharmaceutical manufacturing, sterilization systems, and other hygienic industrial applications where accurate temperature measurement and high system reliability are essential. Its duplex (2+2 wire) configuration incorporates two independent PT100 sensing elements, allowing one element to serve as a backup or secondary measurement channel for critical processes.
The sensor features a steam-tight SS316 construction designed to withstand repeated autoclave and sterilizer cycles. Unlike sensors intended only for occasional wash-down, this design is suitable for applications involving frequent exposure to high-temperature steam and cleaning processes.
The Class A PT100 sensing elements provide high measurement accuracy over a -50°C to 400°C operating range. The Teflon/Teflon insulated cable offers excellent resistance to heat, moisture, and cleaning chemicals commonly encountered in hygienic processing environments.
This Duplex RTD Sensor is widely used in food processing plants, dairy facilities, beverage production, pharmaceutical manufacturing, pasteurization systems, sterilizers, autoclaves, and packaging equipment, where dependable temperature monitoring supports product quality, regulatory compliance, and process validation.
Key Features
-
Steam-Tight Autoclave-Rated Sealing Advanced sealing technology resists vacuum and high-pressure steam cycling without internal condensation or insulation breakdown.
-
Duplex (2+2 Wire) Redundant Architecture Houses two separate PT100 elements within one sheath, providing backup measurement or dual monitoring (e.g., local control PLC plus a backup batch data recorder).
-
High-Precision Class A PT100 Elements Delivers tight accuracy ($pm 0.15^circtext{C}$ at $0^circtext{C}$) to meet strict food safety, HACCP, and pharmaceutical sterilization standards.
-
Hygienic SS316 Stainless Steel Sheath Smooth, corrosion-resistant SS316 surface prevents bacterial entrapment and simplifies wash-down and sanitation routines.
-
Moisture-Proof Teflon Cable (TF/TF) 1-meter lead wire insulated with high-grade Teflon prevents water, oil, steam, and cleaning chemicals from degrading internal conductors.
-
Wide Thermal Range (-50°C to 400°C) Covers everything from deep-freeze storage and flash chilling to high-temperature baking, frying, and steam retorting.

FAQs
1. What is a Duplex RTD Sensor?
A Duplex RTD Sensor contains two independent PT100 sensing elements housed within a single probe, allowing redundant temperature measurement or simultaneous output to two separate monitoring or control systems. This design improves reliability in critical industrial processes where continuous temperature measurement is essential.
2. Why is a Duplex RTD used in Food Processing?
A duplex RTD provides enhanced process reliability by allowing one PT100 sensing element to continue operating if the other requires maintenance or fails. It can also supply a second temperature signal for monitoring, validation, data logging, or process control in critical food production and hygienic applications.
3. What makes this RTD suitable for Autoclaves and Sterilizers?
Its steam-tight construction is designed to withstand repeated steam sterilization and autoclave cycles while maintaining accurate and reliable temperature measurement. This makes it suitable for high-humidity, high-temperature environments commonly found in sterilization and hygienic processing equipment.
4. What industries commonly use this RTD Sensor?
Duplex RTD Sensors are widely used in food processing, dairy plants, beverage production, pharmaceutical manufacturing, autoclaves, sterilization equipment, biotechnology, clean-in-place (CIP) systems, and other hygienic process industries where reliable and continuous temperature monitoring is required.
