It is commonly found in the BioTech and Pharmaceutical industries. Type S Thermocouple (Platinum Rhodium – 10% / Platinum): The Type S is used in very high temperature applications. Type N Thermocouple (Nicrosil / Nisil): The Type N shares the same accuracy and temperature limits as the Type K. Type E Thermocouple (Nickel-Chromium/Constantan): The Type E has a stronger signal & higher accuracy than the Type K or Type J at moderate temperature ranges of 1,000☏ and lower. Type T Thermocouple (Copper/Constantan): The Type T is a very stable very accurate thermocouple that can be used for extremely low temperature applications such as cryogenics or ultra low freezers. Lower temperature range and a shorter lifespan at higher temperatures than the Type K but with much better accuracy. Type J Thermocouple (Iron/Constantan): The type J is also very common. Special limits K-type thermocouple: +/- 1.1☌ or 0.4%.Inexpensive, accurate, and reliable, with a wide temperature range. Type K Thermocouple (Nickel-Chromium / Nickel-Alumel): The type K is the most common type of thermocouple. No wires means system installers can position the sensors almost anywhere a signal can reach. In a wireless data logger, the sensors transmit data samples wireless to a central control device. Wireless Data Logger: A wireless data logger allows for greater flexibility and post-construction applications. This is why it is important to have a dependable and accurate data logger involved in any process where human life is concerned. A disaster waiting to happen since any compromise in the curing process could end in disaster. Imagine concrete used for a bridge or high-rise building without the ability to review temperature/humidity history from pour to cure. In order for concrete to maintain structural integrity, it must cure at a very specific temperature and humidity level. Another example might be a data logger in commercial construction. Likewise with a great number of medicines and organic/biological applications. If at some point the temperature drops in the vaccine fridge while no one is actively monitoring it, the vaccines could become ineffective and no one would ever know…until it was too late. For instance, a data logger may be used in a pharmaceutical application or medical office where a temperature sensor is monitoring a medical refrigerator housing expensive vaccines. It is common for data loggers to provide data that may save lives or prevent catastrophe.
This gives anyone interested, an exportable data set to determine what environmental conditions existed at any point in time. Probably one of the most widely utilized features of commercial data loggers available is the ability to collect and store data 24 hours a day, 7 days a week. From ensuring food safety to maintaining sterile conditions in medical facilities, data loggers are an integral part of day-to-day life. If temperature and relative humidity (RH) are collected by a data logger, then there must be a temperature sensor calibrated to sense and report temperatures being monitored and a humidity sensor that can detect the amount of water in the environment.ĭata loggers are used in almost all industries in the industrialized world.
This logged data can be many things, but in most cases a data logger collects temperature and humidity information from a specifically defined environment.ĭata loggers typically consist of a master control unit (to set data collection intervals, set threshold boundaries and to export collected data) and an array of sensors which actually sample the environment and report information. A data logger is basically a digital recording device that stores data at specific intervals.
