Dpstar is a professional temperature sensor supplier in Malaysia. We provide a wide range of sanitary probes & solutions for process measuring & control for dairy, F&B & life sciences industries. They are perfect for easy handling, quick use temperature measurement. This wide array of sensors will keep your sanitary liquid processes clean and running smoothly.

The 3-A approved MRS-H 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 MRS-H Series RTD probe assemblies are available in standard lengths from 3 to 6″, with a 4-wire Pt100 Class A element (100 ±0.06Ω at 0°C) that is compatible with 3-wire RTD instrumentation. These heavy-duty probes have a 3⁄8″ diameter, which steps down to a 3⁄16″ dia at the probe tip, for fast response and additional strength. Standard features include a 1½” 16 AMP Tri-Grip fitting, type NB9W white polypropylene protection head with screw cap.

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 you can temperature monitor a CCP ( Critical Control Point) or sanitation time and move toward a HACCP (Hazard Analysis Critical Control Point) compliance plan.

Please consult sales for available options, including element types and curves, probe lengths, protection heads, and sanitary fitting styles.

How Thermocouple Probe Works?

Thermocouple probes operate on the principle that an electromagnetic force (emf) is generated when heat is applied to the junction of two dissimilar metals (sending junctions). At the other end of the wires, usually, as part of the input instrument, is another junction called the reference junction. The temperature is inferred based on the emf difference between the sensing and the reference junction, which is at a known temperature. Thermocouple probe junction types include exposed junction, ungrounded junction, and grounded junction.

Thermocouple Probe Junction Types

Sheaths with small diameters have faster response times; sheaths with larger diameters have longer life and are better for measuring higher temperatures.

Exposed Junction has the fastest response time, ideal for measuring rapid temperature changes. Clear coating on most models provides a humidity barrier for the thermocouple. Do not use with corrosive fluids or atmospheres.

 

Ungrounded Junction has a welded junction insulated from the protective sheath and is electrically isolated. Longer response time; use for conductive solutions or where isolation of the measuring circuitry is required.

 

Grounded Junction has a junction welded to tip of sheath. Wires are completely sealed from contaminants. Good response time.
