Protection Head 10,000Ω Thermistor Probes 3-A Sanitary – Maltec-T MHS-S Series

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 MHS-S Series Thermistor 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 requirements of ASME BPE-2007 and 3-A Specification 74-05 and are welded and processed to provide a clean, smooth, 32 µinch or better surface finish in the wetted areas for easy cleaning.

The MHS-S Series thermistor probe assemblies are available in standard lengths from 3 to 6″, with standard 10 kΩ (44006) thermistor elements. Standard features include a 1½” 16 AMP Tri-Grip fitting, type NB9W white polypropylene protection head with screw cap. The probe stems are manufactured with a standard ¼” diameter probe for standard duty service.

This sensor is available with either a white polypropylene screw-top connection head (NB9W) or a stainless steel screw-top connection head (NB15) for connection to your process instrumentation. These sensors are also available in RTD and Thermocouple styles to accommodate any process input requirement. In addition to the standard 1½-16AMP flange design, this sensor can be provided in a wide variety of flange sizes and styles. If you need something a little (or a lot) different, we can accommodate your needs.

This sensor is stocked with the 10,000Ω thermistor standard, but is available in any of the following resistances:

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.
