A data logger is a useful data acquisition device with various industrial applications. The device is used in several industries to record different measurements like temperature, pressure, and humidity, which need to be maintained for manufacturing a quality product.
There are several types of data loggers available, and they do not have the same capabilities. Hence, you must be careful while selecting one. Here we have shared useful tips to choose the right data acquisition device.
What Do You Need to Monitor?
A data logger is a generic word to describe a data acquisition device. The first step in selecting the right device is to determine what you want to measure. For example, you can monitor and record the following things:
- Water Level
You need to know there are different types of data logging instruments to consider. Each device records different measurements. Here are some types of data logging devices:
Temperature/Humidity Data Logging Devices
The humidity/temperature data logging devices can monitor and record temperature and humidity over a certain period. They have internal memory, and they can record measurements (temperature/humidity) at specific intervals and store the readings.
You can buy separate devices to record temperature and humidity. You also have an option to buy a device that offers both functions. The temperature and humidity data logging devices can measure relative humidity and ambient temperature and store around 1 million readings.
Electrical Power Data Logging Devices
Electrical power data logging devices are used for energy audits. They help check energy efficiency, track sub-metering costs, and evaluate energy-saving elements.
The electric power usage is always changing. The devices help you find when and where power consumption is happening and put in usage strategies for efficiency.
General Purpose Data Logging Devices
The general-purpose data logger supports multiple measurements. They have a wide range of sensor types.
Where Would You Locate the Data Logging Device?
Not all data logging devices are built strong. Only a few devices can withstand a harsh environment. Hence, you need first to determine where the data logging device would be located.
You need to check the specification on the device to get the required information. If the device is installed outdoors, it should be waterproof. If you plan to install this device in a hot environment like cooking processes, make sure it can withstand extreme heat.
How Often You Need the Data?
Most data logging devices are battery-operated, standalone devices. After their installation, they continue to record measurements and store data. In most scenarios, the device is retrieved, and the data is downloaded to the computer.
If you need the measurements daily, you need to look for wired data logging devices. These devices can be connected to the computer, and you can access daily measurements.
The three steps given in the post will help you identify the right type of data logging device for your application. No matter its purpose, a suitable data logger is an essential tool to save your time and labour.
