3-A Sanitary RTD Probes with Class A Accuracy - Diameter: 9,6 to 4,8 mm (3/8" to 3/16"), Lenght: 10 cm (4"), Process connection size: 1,5", Process connection type: Tri-Clamp



3-A Approved Design, Along with ASME-BPE-2007 Flange Geometry, Insures Trouble-Free Cleanability and Interchangeability. Can Be Used in Sanitary, Hygienic and Clean-In-Place Food, Dairy, Beverage and BioPharmaceutical Processes. Wetted Surfaces are 316L Stainless Steel, Surface Finish = 32 Microinch or Better. Standard Duty ¼" (0.250") Diameter or Heavy Duty Stepped 3⁄8" to 3⁄16" Diameter Probes Available. 4-Wire, Pt100, Class A Platinum RTD Sensor (100.00 ±0.06 Ω at 0°C) Standard. Process Measurement Temperature Range: -50 to 200°C (-58 to 392°F). Compatible with 3-Wire and 2-Wire RTD Instruments & Transmitters. More
The 3-A Approved OMEGA™ PRS-S-NB9W and PRS-H-NB9W Series RTD Sensors are designed for use in Sanitary or Hygienic Clean-in-Place applications in the Food, Dairy, Beverage and BioPharmaceutical industries. These sensors are manufactured with 316L stainless steel housings that meet the dimensional and finish requirements of 3-A Standard 74-05 and ASME BPE-2007, and are welded and processed to provide a clean, smooth, 32 microinch or better surface finish in the wetted areas for Clean-in-Place processes.
The probe stems are manufactured in two configurations; with a standard 1/4" diameter probe for standard duty service, and a stepped 3/8" to 3/16" diameter probe design for good response times in heavy duty applications. A white polypropylene connection head provides a convenient 3/4' NPT threaded connection point for process wiring.
Food process hygienic temperature sensors can be used to aid food safety inspection compliance and verification of time temperature control. Combined with a chart recorder model CTXL you can temperature monitor a CCP ( Critical Control Point) or sanitation time and move toward a HACCP (Hazard Analysis Critical Control Point) compliance plan.

How is Temperature Measured?
Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. Six types with which the engineer is likely to come into contact are: thermocouples, resistive temperature devices (RTDs and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices.

RTD vs Thermocouple
It is not practical to compare RTDs and thermocouples generally. However, if we compare their performance in terms of specific criteria, we can see which is best suited for specific applications. Thermocouples are best for working at high temperatures. New manufacturing techniques have improved the measurement range of RTD probes, but more than 90% of RTDs are designed for temperatures below 400°C.
In contrast, some thermocouples can be used at up to 2500°C. Thermocouples are generally cheaper than RTDs...
