Description
Tri-Clamp RTD Sensor (Model APSS-6) is a compact PT100 hygienic temperature sensor developed for sanitary process applications where installation space is limited and all-stainless construction is preferred. Featuring a Simplex PT100 Class B sensing element, a miniature stainless steel terminal head, a hygienic Tri-Clamp (Tri-Clover) process connection, and a 100 mm insertion length below the fitting, this RTD sensor provides dependable temperature measurement across an operating range of -50°C to +400°C. Compared with conventional sanitary RTD assemblies that use larger aluminium terminal heads, the compact stainless steel housing reduces the overall installation footprint while maintaining convenient access for wiring and maintenance.
Designed for hygienic processing environments, the APSS-6 combines smooth stainless steel construction with a compact head profile suitable for equipment where surrounding clearance is restricted. The all-stainless terminal head also makes this sensor an attractive option for facilities that prefer stainless steel instrumentation throughout hygienic production areas. Manufactured by Aavad Instrument, this Tri-Clamp PT100 RTD sensor integrates with compatible temperature transmitters, PLCs, DCS, SCADA systems, controllers, and industrial automation platforms, making it ideal for food processing, dairy production, beverage manufacturing, pharmaceutical facilities, biotechnology plants, and hygienic OEM equipment.

FAQs
1. What is a Tri-Clamp RTD Sensor and how is it different from a standard Sanitary RTD?
A Tri-Clamp RTD Sensor is a PT100 Resistance Temperature Detector (RTD) designed with a hygienic Tri-Clover (Tri-Clamp) process connection and a miniature all-stainless-steel terminal head. Unlike conventional sanitary RTD sensors that typically use larger die-cast aluminum heads, this design provides a compact installation footprint and 100% stainless-steel construction, making it ideal for hygienic and contamination-sensitive applications.
2. Why would a facility require Aluminum-Free RTD Sensor construction?
Many pharmaceutical, biotechnology, food, dairy, and high-purity process facilities restrict the use of aluminum components to minimize contamination risks and comply with strict hygienic manufacturing standards. Aavad’s Model APSS-6 features an all-stainless-steel terminal head, making it suitable for these demanding sanitary applications.
3. What are the specifications of Aavad’s Tri-Clamp RTD Sensor?
Aavad’s Model APSS-6 is a simplex 3-wire PT100 RTD Sensor with Class B accuracy and an operating temperature range of -50°C to +400°C. It features a 6 mm outer diameter (OD) SS316 probe, a 100 mm insertion length below the Tri-Clover (Tri-Clamp) fitting, and a compact stainless-steel terminal head for hygienic process installations.
4. Is the Tri-Clamp RTD Sensor suitable for CIP/SIP cleaning cycles?
Yes. The all-stainless-steel hygienic construction is designed to withstand CIP (Clean-in-Place) and SIP (Sterilize-in-Place) cleaning processes, including chemical wash cycles, pressurized cleaning, and high-temperature steam sterilization, making it ideal for sanitary process industries.
5. What industries use Tri-Clamp RTD Sensors?
Tri-Clamp RTD Sensors are widely used in pharmaceutical manufacturing, biotechnology, food processing, dairy plants, breweries, beverage production, hygienic process systems, sanitary processing skids, and other industries requiring compact, all-stainless-steel temperature sensors with hygienic Tri-Clover process connections.
