Description
Pot Seal RTD Sensor (Model APES-6×100) is a PT100 resistance temperature detector designed for industrial applications that require a permanently sealed cable termination. Instead of using a detachable connector or terminal head, the cable-to-sensor junction is encapsulated with high-performance epoxy inside a protective seal pot, creating a durable assembly that resists moisture ingress, vibration, and thermal cycling.
The sensor incorporates a PT100 Class B sensing element with an operating temperature range of -50°C to 400°C. Its SS316 stainless steel sensing probe provides corrosion resistance for demanding industrial environments, while the mineral insulated (MI) construction improves mechanical strength and thermal stability in high-temperature applications.
The permanently sealed termination minimizes maintenance by eliminating connector pins, gaskets, and other removable components that can loosen or corrode over time. This makes the sensor well suited to long-term installations where reliability is more important than quick disconnect capability.
The Pot Seal RTD Sensor is widely used in chemical processing, petrochemical plants, industrial ovens, furnaces, power generation, heat treatment equipment, and OEM machinery, where dependable temperature measurement is required under continuous operating conditions.

FAQs
1. What is a Pot Seal RTD Sensor?
A Pot Seal RTD Sensor is a PT100 Resistance Temperature Detector (RTD) in which the cable-to-sensor junction is permanently sealed with epoxy inside a protective pot seal. This construction improves resistance to moisture, vibration, thermal cycling, and mechanical stress, ensuring reliable and long-lasting temperature measurement in industrial environments.
2. Why choose a Pot Seal Termination instead of a Connector?
A pot seal termination provides a permanent, maintenance-free connection with fewer components that can loosen, corrode, or require replacement. It is ideal for applications where frequent sensor disconnection is unnecessary and long-term reliability is a priority.
3. What is the advantage of Mineral Insulated (MI) Construction?
Mineral Insulated (MI) construction offers excellent mechanical strength, superior thermal stability, fast heat transfer, and high resistance to vibration and elevated temperatures. These characteristics make MI RTD sensors well suited for demanding industrial applications requiring reliable and accurate temperature measurement.
4. Where are Pot Seal RTD Sensors commonly used?
Pot Seal RTD Sensors are widely used in chemical plants, petrochemical facilities, industrial ovens, furnaces, power generation plants, heat treatment equipment, process industries, steel plants, pharmaceutical manufacturing, and OEM machinery where durable, maintenance-free temperature sensing is required.
