Data Logger Vs Data Acquisition- How They Differ?


The importance of a highly reliable and efficient temperature monitoring system cannot be taken for granted. Once the system starts failing, negative effects start occurring. It also leads to unexpected incidents like losing stored stem cells. 

Implementing a real-time monitoring system including Data Acquisition in the laboratory system will be a great idea. The system that you are about to include must be highly accurate, flexible, easy-to-handle, and robust. 

An Insight to Data Loggers!

Every laboratory requires a particular device where data can be stored and can be easily extracted. There are numerous devices, but a data logger will be the best. This device will record the temperature of the entire lab. It will notify in case any deviation takes place that may cause any adverse effect to the samples. 

Data loggers serve as reactive ways of monitoring deviations in numerous cases. Otherwise, it may become too difficult to come across discarded samples.

Along with a logger, a temperature sensor is a particular device that will measure the temperature in case of specific equipment. Also, it will transmit the data to a device that will serve as a repository. This temperature is very important and must be watched diligently as a little bit of deviation may affect samples poorly.

What is the Difference between Data Acquisition System and Data Logger?

There is confusion between data acquisition and data logger. Some people presume that both are the same. But it is just the reverse. Below are some vital differences that exist between the two:

In case of an alarm, the data acquisition system will permit you to log in virtually. You will be able to come across notifications while capturing every movement prior to and post the alarm. 

On the other hand, a data logger will let you interrupt in between the logging sequence. Doing so will let you diagnose issues. But there will be a risk of missing any information between the logs. 

  • Differs in terms of configuration – Usually, the data acquisition system is a configurable system. It will give you the provision to set parameters for alarm. In case you are monitoring the water level in a tank, you may set up the alarm to notify overflowing. Also, you may set a pre-alarm and give yourself enough time before it starts overflowing. 

Whereas, in the case of a data logger there are chances that you may miss out on the target. The system is such that it will result in some type of interruption. 

  • High accuracy level – A data acquisition system is known for its high accuracy level. It will let you set sample rates at an interval of a second. It will serve as a time savior and will ensure a high level of accuracy. 

Whereas, in the case of data loggers; the time taken for setting sample rates is a minimum of fifteen minutes. It helps in preserving battery life. 

After going through the comparison in detail, it is for sure that you have come across the difference between data acquisition and data logger. For better performance, it is preferable to go with data acquisition as it helps in improving SOPs through valuable information.

Pressure Transducers Explained: How to Choose the Correct Type for Your Application

Do you ever wonder how people know how much pressure is being exerted on them in different settings? Or maybe you've been asked to build a scenario where someone would know how much pressure is being exerted on them? If so, you're not alone! As the saying goes, no good without 'pressure.' Pressure is an essential part of any scenario where you have to know how much force is being exerted on you. Pressure is a dynamic variable that is measured by pressure transducers. In this article, we will be going over some of the common types of pressure transducers , their benefits, and applications where they make the most sense. What is Pressure? Pressure is a force exerted on an object that can be measured. There are two types of pressure: Static and Dynamic. Static pressure is the amount of force required to move an object up or down in a fluid, while dynamic pressure is the amount of force required to move the object either left or right in a fluid. Types of Pressure Transd...
