Categories Related to Temperature Loggers
Temperature loggers are data loggers that measure temperature and record and store temperature data at arbitrary intervals.
Temperature loggers are widely used when temperatures need to be measured continuously, such as in the transfer of food or temperature control in cultivation.
Applications for temperature loggers are diverse and include all industries that must ensure that temperatures are suitable. The following are some of the main applications:
A temperature logger is a device that measures temperature at set intervals and digitally processes and stores the results. Depending on the product, the measurement interval can be selected from seconds to hours.
In the old days, constant measurements of air and liquid temperatures were periodically recorded with a colored pen on a roll of paper with a graph axis printed on it. Similar temperature recorders are still in use today and are called temperature recorders. Temperature loggers are expensive, require special pens and recording paper, and are difficult to store and analyze data.
Temperature loggers were developed as compact temperature loggers. The data conventionally recorded with a pen is stored in a storage medium called a logger. Compared to temperature loggers, temperature loggers are easier to use in the following ways:
Currently, temperature loggers can be placed in shipping containers or in warehouses to measure temperature deviations and help improve quality levels.
A temperature data logger basically consists of a temperature sensor, memory, and battery.
The temperature sensor can be a thermistor, thermocouple (K, T, J), or platinum resistor, depending on the temperature being measured, and the required accuracy. Infrared sensors are also used to measure surface temperatures.
In general, most batteries are replaceable, but for ultra-compact types and autoclaves that are used under pressure, the entire battery is covered with metal and cannot be replaced.
There are various types of temperature loggers on the market, depending on how they are used and the temperature at which they are used.
This type is used for indoor measurements. They are designed with a digital display so that the temperature can be checked while the device is in place.
Some are waterproof, and others have a temperature sensor attached to the probe to enable measurement in confined spaces. Data can be transmitted wirelessly, by cable, NFC, Bluetooth, etc.
Infrared sensors and temperature sensors with magnets are used to measure surface temperatures.
Autoclaves are also called high-pressure steam sterilizers. Autoclaves can sterilize heat-resistant spores. However, since the temperature in an autoclave is not constant, it is necessary to confirm that the environment is suitable for sterilization. Therefore, it is necessary to check the temperature at several points in the autoclave. For this purpose, we use temperature loggers that are encased to withstand high pressure.
Temperature loggers are also used for temperature mapping in high-pressure processing environments, such as retort pouch foods and canned foods.
A reflow oven is used in the process of bonding printed circuit boards and electronic components with solder, which requires a temperature rise of 150°C to 230°C. To measure this constant temperature, a temperature logger is used. To measure this constant temperature, a temperature logger is placed in a heat-resistant case.
Temperature loggers for ultra-low temperatures, such as those used in freeze-drying processes and deep freezers, can be used to confirm that vaccines and strains of bacteria are properly stored.
Smaller than a button cell, these data loggers are used in containers or boxes during shipment.
