Integration with various industrial devices, sensors and control systems
UA20-E supports MODBUS® RTU protocol and converts RS485 communication into USB digital signal. It is automatically recognized as a serial port via USB, making it easy to build a multi-channel sensor network.
-

-
Trending IoT, digital data output
It is automatically recognized as a USB-SERIAL device in Windows, Mac, Android and Linux using USB CDC.
Do you know the AT commands used in telephone modems? You can easily obtain sensor information with just AT commands. Obtain information easily with AT commands.
-

-
Easy maintenance, calibration by pulling out like USB
In Korea, it is recommended to calibrate the sensor once a year to check the accuracy of the sensor. Since the UA Series is a USB type sensor, calibration and sensor replacement are very convenient. Ah! You can use it simply by plugging it into a USB port without any installation work, so cost savings can be realized now.
-

-
Remote monitoring, software provided
The advantage of UA products is that they enable real-time recording. We have prepared a variety of software to enable real-time recording with only UA devices. There are Tapaculo Lite (a program for PC) and Tapaculo Mobile (an Android app). After installing the software, connect the UA device to USB.
