The data logger first appeared as a portable electronic device in the late 1970s and they evolved quickly into the popular instruments we know today. The analogue and digital inputs on a data logger haven't really changed a lot over the years, although we have seen the introduction of serial data sensors using ASCII, SDI-12 or MODBUS protocols as inputs sensors. Wireless sensors are slowly taking hold too and are improving all the time.
Internal memory storage was always an issue until the turn of the 21st century when Compact Flash memory or Compact Flash memory cards where used as onboard memory storage. Secure Digital (SD) memory cards are now replacing Compact Flash memory cards for internal data storage. The USB flash drive port for data transfer first appeared on a data logger in 2005.
Communications is one area where the data logger has evolved. Most data loggers now support USB data communications instead of the more reliable RS232 format. More featured data loggers have built in Ethernet TCP/IP sockets, Wi-Fi and Bluetooth for wireless communications. Today, the Internet of Things is all the talk and new IOT standards are taken shape for the future.
Lontek sells a wide range of data loggers for just about every application. We specialise in data logging and data acquisition equipment for various industries. Although our focus leans a little towards mid range data loggers that could be considered a bit more technical than the average single channel unit.
A good selection of the products we sell is listed here on the Lontek online shop, so if you just quite see a unit here that fits your requirements, then feel free to give us a call to discuss. The chances are we will have an option for you or we can recommend one of our local industry colleagues that should be able to assist.
