As the name suggests, a temperature data logger is a device that measures ambient temperature and maintains a record of the same. The internal specifications of the temperature data logger determine the duration of the intervals at which this information is recorded.
A temperature data logger contains conductors or resistors that generate an electric charge of varying voltages depending on the measured temperature. The chip measures the electric charge to corresponding to the external temperature. This information is converted into digital format and stored in the internal memory of the device. The data can be accessed through cables, RFIDs, wireless transmitters, or even through the USB interface.
Application of temperature data loggers in various industries are listed below:
Environmental Monitoring and Protection
Temperature data loggers are widely used to measure environment temperature conditions to analyze various patterns. The data can be collected over months and years across different geographical locations to analyze the data. Often such temperature data loggers are part of weather stations which collect various data apart from temperature.
The information generated by the temperature data logger can be collected and analyzed to draw conclusions about the speed at which global temperatures are rising or falling and reasons for such changes.
Temperature data loggers for Manufacturing Industries
A temperature data logger that is designed to transmit its data wirelessly to the control room at regular intervals can help manufacturing industries track the temperature in areas and machines where manual measurement of information is impossible. A person cannot just walk into a 2000°C blast furnace to measure its temperature. On the other hand, a temperature data logger designed to operate under such extreme conditions can provide a steady stream of data that can be used to optimize production metrics and ensure safe working conditions at all times.
Temperature data logger for Food Processing Industry
The temperature data logger plays a very important role in ensuring processed foods are transported over long distances in compliance with all food safety norms. Temperature needs to be monitored under various stages of good processing including storage, transportation, processing, cooking etc. We have various type of measuring instruments and reusable data loggers for recording temperature throughout all the different stages.
The information recorded by the temperature data logger will serve as proof that mobile cold storage vehicles transported the foodstuffs under optimum conditions throughout the journey. The reusable data logger can be used any number of times.
Data loggers for Pharmaceutical Industry
Just like the food industry, the temperature data logger acts as a useful tool for quality assurance by tracking temperatures within the manufacturing plant, and throughout the supply chain to minimize the risk of degradation of the medicines.
Temperature monitoring and recording is extremely critical in the Pharmaceutical industry, considering that medicines, vaccines etc. are very sensitive to change in temperature and the efficacy is drastically reduced by such variations.
Without data loggers, implementation of quality standards would have been virtually impossible.
Selection of Temperature Data Loggers
In order to select the right data logger please review the following requirements:
- What is the temperature range to be measured?
- What is the sampling interval required? The sampling interval is the frequency at which you are measuring the temperature. If you are recording at an interval of 10 minutes, it means that sampling interval is 10 minutes.
- What is the memory capacity required? The sampling interval is also important for deciding the memory capacity. most of the manufacturers will be specifying the memory capacity in a number of readings. So a device with a memory of 8000 readings can store up to 8000 readings continuously. So if sampling interval is 5 minutes, it will record 12 readings per hour, 288 readings per day. This means that for a data logger having a memory of 8000 readings, this will last for 27.7 days. So once the data logger starts recording, it will continue recording for 27.7 days. For the same data logger, if you keep a sampling interval of 10 minutes, the number of days will be double to 55.4 days.
- What is the accuracy required? there are various models with an accuracy of 0.1°C, 0.3°C etc.
- What is the resolution required? Resolution is the decimal points displayed on the screen. If the screen shows 25.1°C, 25.2°C etc., this means the resolution is 0.1°C. If the display is 25.0°C, 25.5°C, 30.0 °C etc, the resolution is 0.5°C. If the display is 25.01°C, 25.02°C etc, the resolution is 0.02°C
- Is there any software fee? We provide numerous data loggers with free software
- Is the battery easily replaceable or you have to take to the dealer? We have numerous models which operate on simple coin type cells, which can be simply replaced by the user by removing the battery cover on the back side.
- Do you require internal sensors or external sensors? If you have a medicine box and you want to see the temperature outside the box without opening the box, you will need a temperature data logger with an external sensor. The external sensor will be inserted into the box and the logger with the display will be placed outside the box.
- Do you require single-use or multi-use data loggers? Single use data loggers are the disposable type for a single use. Multiple use types can be reused any number of times. Multiple use ones are also known as reusable data loggers.
