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.

This Sanitary Temperature Sensor contains a PT100 Platinum RTD element and is designed for use in Food, Dairy, Beverage, and BioPharmaceutical Clean-In-Place (CIP) type applications. The sensor includes a 1½” 16AMP process connection that conforms to ASME BPE-2007 for easy installation using industry-standard gaskets and clamps. Standard Duty sensors are available with ¼” diameter probes, and Heavy Duty sensors are available with a stepped 3⁄8″ to 3⁄16″ diameter probe. This sensor is provided with a 120″ long, 4-conductor, #26AWG stranded nickel-plated copper, PFA insulated, and jacketed cable with strain relief for convenient connection to control or monitoring equipment.

The MRS-S-CB Series RTD probes are available in standard lengths from 3 to 6″, with a 4-wire Pt100 Class A element (100 ± 0.06 Ω at 0°C) that is compatible with 3-wire RTD instrumentation. Standard features include a 1½” 16 AMP Tri-Grip fitting and 10 ft of PFA insulated and jacketed cable with strain relief.

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.

These sanitary sensors are supplied standard as 4-wire assemblies with two red wires and two white wires. When used in 3-wire applications, cut off one white wire making sure that it will not contact any terminals or metal surfaces (note: twisting the two white wires together will reduce the lead wire resistance on one side of the sensing element by half adversely affecting the accuracy of the reading). When used in 2-wire applications, cut off one white wire and one red wire (note: in 2-wire applications, twisting the two same-colored wires together at the terminals will not adversely affect your sensor accuracy since both wires will be affected by the reduction in resistance).

Please consult sales for available options, including element types and curves, probe and cable lengths, 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.
