Data Loggers

Data loggers are devices that are used to record and maintain data with internal and external instruments. Based on a microprocessor or digital processor, they store data in internal memory. Data loggers are of different types and vary between general purpose devices to specific devices that can be one application type only.

Some data loggers can be used as a stand-alone device whereas some interface with a personal computer which uses specific software to activate data logger. Many data loggers remain as stationary machines where only a limited number of parameters can be changed; however, some are commonly used for general purpose programming.

During activation, data loggers are installed to measure and provide an accurate and comprehensive picture of monitored conditions like humidity and temperature of air.

Data loggers have the ability to collect data and information on a 24-hour basis automatically. As the technology is improving, the cost of data loggers is declining. Simple data loggers cost a little and vice versa. Vacker UAE provides a wide range of data loggers to collect and record data and information.

Data formats

YAML, XML, and JSON are being accepted for the exchange of data as standardization of protocols and formatting data have become a huge problem in the industry. The Internet of Things and Semantic Web are accelerating the present trend.

Instrumentation Protocols

Some instruments can be connected to a variety of data loggers with the help of smart or standardized protocol. It is being used basically in the environmental industry and not accepted outside this field. A new multi-drop protocol known as the MODBUS standard is being highly accepted in data logging companies. It is becoming very popular in the industrial control area as it supports the communication standard by using various instruments. Vacker UAE is a leading company that provides a wide range of instrumentation protocols in different cities of UAE, like Dubai, Abu Dhabi, Ras al Khaimah, Umm al Quwain, Sharjah and Fujairah. To adapt themselves to various non-standard protocols, data loggers have started to use a flexible scripting environment.

Data Logging versus Data Acquisition

Data acquisitions are also used as a substitution for data logging but are quite different from each other. Data acquisition system is not essential to be a data logger but data logger is a data acquisition system. Data acquisition has a fast sample rating process than the data logger. Data acquisition system unites with the computer to gain data, while data loggers are considered to be stand-alone devices. Data loggers are generally used to store acquired data. Magnetic tape or strip chart recorders are used by data loggers. The new range of data loggers serves web page which allows people to start an isolated system. Some applications in data loggers need to operate from a power source such as battery and solar power as they are left unattended. As data loggers need to work in difficult environmental situations so they need to be very power efficient. The isolated nature of data loggers make the manufacturers make it very reliable and immune to the problems like program crashing and ignorance of some operating system.

We, Vacker UAE, go through a great extent to ensure that our valuable customers get devices that they can fully rely upon. We provide our services in Sharjah, Fujairah, Dubai, Abu Dhabi, Umm al Quwain and Ras al Khaimah.

Applications

Data loggers are used in various fields. They, once installed, are left unattended and remote so that the users do not have to check it on a regular basis. This helps to record and store data and information of things related to environmental changes and research work based on anything whose data needs to be accurate. Data loggers can be used in storing information regarding wind speed, humidity, radiation, the direction of the wind and radiation. It can be used in agricultural fields to record the level of soil moisture and fertility. Vehicle testing, crash testing and motor racing also need data logger. The data logger is used in science education too for the measurement, appreciation of change and scientific education. For the groundwater studies, data logger helps in monitoring water level. Some examples of data loggers that are found in the market are:

1. Voyage data recorder(VDR), to record various sensors on ship.
2. Cockpit voice recorder (CVR) or Flight data recorder (FDR), which records device found on board aircraft.
3. Train event recorder is also a type of data logger which keeps the record and controls the performance of the train.
4. A device is usually installed in automobiles that keep the record of various data during a period of time, also known as Event data recorder (EDR).
