Description
The Aavad RTD with Fixed Connection (Model APWS-6×75) is a high-accuracy PT100 RTD temperature sensor designed for fast, consistent, and reliable industrial temperature measurement in OEM machinery, process equipment, and fixed installations. Featuring a permanently fixed 1/2″ BSP(M) threaded process connection, Class A PT100 sensing element, and durable SS316 stainless steel sheath, this industrial RTD sensor eliminates the need to manually adjust the insertion depth during installation. With a wide operating temperature range of -50°C to +400°C, compacted MgO insulation, and a fixed 75 mm probe length, the sensor provides stable and repeatable temperature measurement while simplifying installation in high-volume OEM production and standardized industrial equipment.
Engineered for demanding industrial automation and process temperature monitoring, the Model APWS-6×75 features a rugged IP65 die-cast aluminium terminal head with a threaded cap and security chain, providing dependable protection against dust, moisture, vibration, and harsh operating conditions. The fixed process connection ensures consistent sensor positioning and repeatable immersion depth across multiple installations, making it ideal for machine builders, OEM manufacturers, skid integrators, HVAC equipment, chemical processing systems, and packaged process units. Manufactured by Aavad Instrument, this fixed connection RTD sensor can be customized with different probe lengths, thread sizes, sheath materials, and configurations to match specific equipment drawings and industrial temperature sensing requirements.

FAQs
1. What is an RTD with Fixed Connection and why choose it over a Compression-Fitting RTD?
An RTD with Fixed Connection is a PT100 Resistance Temperature Detector (RTD) featuring a permanently threaded process connection instead of a removable compression fitting. This design simplifies installation, reduces assembly time, and provides a secure mounting solution for OEM machinery, industrial equipment, and process control applications. Aavad’s Model APWS-6×75 is a Class A PT100 RTD with a 1/2″ BSP (Male) fixed process connection, operating from -50°C to +400°C.
2. What is the construction and protection level of Aavad’s RTD with Fixed Connection?
The sensor features an SS316 stainless steel sheath with compacted Magnesium Oxide (MgO) insulation, a die-cast aluminum protection head with a threaded cap and retaining chain rated IP65, a ¾” ET cable entry, and a 6 mm outer diameter (OD) × 75 mm probe length below the head for reliable industrial temperature measurement.
3. Is the RTD with Fixed Connection customizable for OEM production runs?
Yes. Aavad Instrument manufactures RTD Sensors with Fixed Connections to customer specifications. Process connection size, probe length, sheath diameter, sensing element configuration, and wiring arrangement can all be customized to match specific OEM equipment, machinery designs, and production requirements.
4. What media can this Fixed-Connection RTD measure?
This Fixed-Connection PT100 RTD Sensor is suitable for measuring the temperature of both liquids and gases. It is widely used in OEM machinery, HVAC and refrigeration systems, chemical and petrochemical plants, process industries, and industrial automation applications.
5. What accuracy class does the Fixed-Connection RTD Sensor offer?
The sensor is supplied with Class A PT100 accuracy as standard, providing higher precision, better repeatability, and tighter measurement tolerance than Class B RTDs. This makes it ideal for OEM equipment and industrial applications requiring consistent and reliable temperature measurement.
