Description
Replacement PT100 RTD Probe (Model APES-6×150) is a Class A PT100 temperature sensor designed as a replacement sensing probe for existing industrial equipment. Unlike RTD sensors with fixed process connections, this model is supplied as a bare probe, allowing it to be installed into compatible thermowells, compression fittings, or OEM mounting arrangements already in service.
The sensor features a PT100 simplex 3-wire element that provides accurate and repeatable temperature measurement over a -50°C to 250°C operating range. Its SS316 stainless steel sheath offers corrosion resistance and durability, while the TF/TF/SS (Teflon insulated with stainless steel braided) cable provides protection against heat, abrasion, oils, and industrial environments. The standard 5-meter cable simplifies replacement where the control panel or junction box is located at a greater distance.
This replacement RTD probe is suitable for restoring temperature measurement in existing systems without redesigning the installation. It is commonly used in process industries, OEM machinery, HVAC systems, power generation equipment, chemical plants, and automation systems where maintaining equipment uptime is essential.
As a leading RTD sensor manufacturer in India, Aavad Instrument Pvt. Ltd. manufactures replacement RTD probes in customized lengths, probe diameters, sensing elements (PT100/PT1000), cable types, and termination options to match OEM and retrofit requirements.
Key Features
-
Universal Drop-In Replacement Design Plain 6mm sheath slides smoothly into standard industrial thermowells, spring-loaded terminal heads, or adjustable compression fittings.
-
Class A Accuracy PT100 Element Delivers high precision and long-term stability ($pm 0.15^circtext{C}$ at $0^circtext{C}$), making it ideal for recalibrating control loops.
-
Extended 5-Meter Armored Extension Lead Ships with a 5m lead cable (TF/TF/SS) to connect directly to remote transmitters or PLCs without junction splicing.

FAQs
1. What is a Replacement RTD Probe?
A Replacement RTD Probe is a PT100 Resistance Temperature Detector (RTD) designed to replace an existing RTD sensor without changing the equipment’s mounting arrangement, thermowell, or temperature control system. It provides accurate and reliable temperature measurement while minimizing equipment downtime.
2. Can this Probe fit into my existing Thermowell?
Yes. A Replacement RTD Probe can fit into your existing thermowell provided the probe diameter, insertion length, and installation requirements match your current thermowell or process fitting. Always verify the mechanical dimensions before replacement.
3. How do I know if this Probe is compatible with my equipment?
To confirm compatibility, verify the sensing element (PT100 or PT1000), wire configuration (2-wire, 3-wire, or 4-wire), probe diameter, insertion length, temperature range, process connection, and termination type against the specifications of your original RTD sensor.
