Labatt’s Brewery is looking to find a temperature sensor which can withstand the conditions of the fermentation processing which occurs in its company. The sensor must be able to operate under a large temperature range (-2C to 200C), while maintain the temperature with at least < +/- 0.5°C accuracy. It should also have resilience to contact with hot caustic NaOH, as a flushes occur between batches in order to clean and sterilize the equipment. Furthermore, it should be non-contact sensor as there should be no chance of contamination that may occur as a result of contact. Labatt prefers a sensor which is low maintenance, this would mean, being mounted for ease of replacements, services and minimal calibration necessary. Additionally, the temperature should be cost effective for the company, while

Since Labatt has stated that the product should be able to withstand hot caustic NaOH, Nickel RTD’s are more suited for this case. Platinum has been experimentally proven to corrode as a result of NaOH contact. This is not suited for Labatt, as the corrosion may cause potential contamination of the product. Nickel is able to withstand hot caustic NaOH contact, and should thus be used.
Since Labatt is requesting a temperature sensor which requires low maintenance, the ease of servicing, maintenance and calibration should be analyzed. RTD’s can be mounted, as requested by Labatt, which will ensure the ease of maintenance as it can then be easily replaced or serviced when necessary. Further, RTD’s require very minimal calibration, as they are generally calibrated every 5 years.
If Labatt’s Brewer were to put a strict budget on the temperature sensor they purchase, RTD’s are still a potential effective candidate. This is because, the price of RTD’s range from $40 to $320. Labatt would be able to purchase a lower end RTD and still have the minimal working conditions of an RTD, which would comply to their company
