Description
Sanitary RTD with Female Nut (Model APIS-Tri) is a compact PT100 sanitary temperature sensor designed for accurate and reliable temperature measurement in hygienic food, dairy, beverage, pharmaceutical, and biotech processing applications. Featuring a 1-inch Tri-Clover (Tri-Clamp) sanitary process connection, durable SS316 stainless steel sensing sheath, and a standard IP67 die-cast aluminium terminal head, this industrial RTD sensor provides dependable temperature measurement across a wide operating range of -50°C to +400°C. Designed primarily for non-classified process areas where a flameproof enclosure is not required, the APIS-Tri provides a practical and economical temperature sensing solution for smaller sanitary pipelines, tanks, vessels, and hygienic process equipment.
Available with 2-wire, 3-wire, or 4-wire PT100 configurations and Simplex or Duplex sensing options, the APIS-Tri can be configured for different process control, indication, accuracy, and redundancy requirements. Its 1-inch Tri-Clamp connection enables convenient installation and removal from compatible sanitary process equipment, while the IP67 terminal head provides protection against dust and moisture in demanding industrial environments. Manufactured by Aavad Instrument, this sanitary PT100 RTD temperature sensor is ideal for process monitoring in food production, dairy plants, beverage processing, pharmaceutical manufacturing, biotech facilities, and compatible CIP process systems requiring hygienic connectivity without the additional cost of a flameproof sensor assembly.

Datasheet
FAQs
1. What is a Sanitary RTD with Female Nut Connection?
A Sanitary RTD with Female Nut Connection is a PT100 Resistance Temperature Detector (RTD) designed for hygienic temperature measurement in CIP (Clean-in-Place) and SIP (Sterilize-in-Place) process applications. Aavad’s Model APIS-Tri features a 1″ Tri-Clover (Tri-Clamp) process connection with a female-nut style fitting, making it ideal for food, dairy, beverage, pharmaceutical, and biotechnology industries.
2. What temperature range and wiring options does this Sanitary RTD support?
This model operates over a temperature range of -50°C to +400°C and is supplied as a simplex 3-wire PT100 RTD as standard. Aavad Instrument also manufactures sanitary RTD sensors with 2-wire, 3-wire, or 4-wire configurations and in both simplex and duplex assemblies to suit various industrial instrumentation requirements.
3. What is the construction of the Female-Nut Sanitary RTD?
The sensor features an SS316 stainless steel sheath with a 6 mm outer diameter (OD), a 300 mm total probe length below the protection head, and a 150 mm insertion length below the 1″ Tri-Clover fitting. It is equipped with a die-cast aluminum IP67 protection head featuring a threaded cap and retaining chain for reliable industrial operation.
4. Why choose a 1″ Tri-Clover instead of a 2″ Tri-Clover Sanitary Fitting?
A 1″ Tri-Clover (Tri-Clamp) fitting is well suited for smaller pipelines, compact process equipment, pharmaceutical systems, biotechnology applications, and dosing lines, while a 2″ Tri-Clover fitting is generally preferred for larger process vessels, tanks, and high-flow food and beverage processing lines.
5. What industries use Sanitary RTD Sensors with Female Nut Fittings?
Sanitary RTD Sensors with Female Nut Connections are widely used in food processing, dairy production, beverage manufacturing, pharmaceutical and biotechnology plants, chemical processing, hygienic pipelines, storage tanks, and CIP/SIP systems, where accurate, reliable, and hygienic temperature monitoring is essential.
