In industries that heavily rely on keeping a regulated and proper temperature ranges, having high quality and accurate sensors is extremely important to meet regulatory temperature compliance. Food, beverage, pharmaceutical and many other industries suffer heavy losses each year as a result of faulty mechanisms that cause high temperature variations. Companies have opted to prevent this type of loss with the use of resistance temperature detectors (RTD’s).
What Is Regulatory Compliance? Regulatory compliance refers to a set of rules, guidelines and regulations, relevant to the business’ processes, which companies must follow. Failure to do so can lead to losses, legal repercussions and even fines. Keeping the temperatures up to regulations is crucial in preventing these worst-case scenarios.
RTD’s are sensors used to measure temperatures between -148 and 932 degrees F (-200 and 500 degrees C). Made from thin length wire that is wrapped around a ceramic or a glass core, they contain a resistor whose resistance changes depending on the temperature. Although there are many different types of these detectors, made from either copper or nickel, platinum RTD’s are most commonly used since they can withstand widest temperature range.
One of the advantages of platinum use is a stable and accurate output over longer periods of time because of its highly predictable change in resistance according to the temperature. Also, platinum is resistant to both oxidation and corrosion. Highly Accurate and Quick Resistance temperature detectors provide higher accuracy than standard thermocouples and are generally used in places where highest precision is extremely important, with variations of about +/- 0.05 degrees.
RTD sensors have quick response times of about 0.5-3 seconds and are very easy to recalibrate. Because of their diverse use, RTD’s come in different sizes and require no special wires to install. With our sensors, you will be able to meet the needs of all the strict temperature measurements and regulations regarding health and safety.
There are numerous configurations with different number of wires that provide varying accuracy. Four wire configurations can be built with the longest cables along with highest accuracy. Food grade RTD’s are waterproof and have no crevices to prevent bacterial growth and simplify cleaning. A wide range of accuracy classes help you choose the best one for your business. These classes are determined by the tolerance of the resistance and accuracy in numerous operating temperatures.
Extremely low drift coupled with moderate resistance to vibrations make them perfect for all industrial occasions. For higher protection against vibrations, RTD’s with ceramic wire wound are commonly used.
Specialized wireless monitoring companies have built platforms to try to offer quick and easy sensor installation service and wireless temperature monitoring. Good stability, wide temperature range, easy installation are all factors that play towards the use of RTD’s in high quality systems. Ultimately, this quality saves long run costs and helps companies stay in line with regulatory temperature compliance.
