DC Current 4-20ma Data Logger

Based on our experienced technology in developing SD card or USB storing, our 4-20ma data loggers are equipped with USB port or SD card. 4-20ma or 0-20ma belongs to DC analog current signal and have been as the most universal signal standard in many industries and have been widely by various of devices. So 4-20ma data loggers are very necessary for 4-20ma devices to store related information and related data.4-20ma data logger with USB EN

4-20ma Data Logger for General Purpose

The 4-20ma data logger is designed for general purpose of 4-20m current reading and it can store 32,000 current reads with 64k bit. The data logger has a USB port to communicate with computer and a data management software can be provied to set parameters.

The data logge software can be installed on Windows XP,Vista, 7 or 8(34 and 64 bit). Becore using, users need to install USB driver and the software. Users can easily use the software to set the following:

1.Sampling period: 10s to 12h

2.Alarm for high/low limit


4.Download data to PC for further process: view,analysis, print or convert to other format,e.g. TXT,XSL,CSV,BMP,JPG.

5.Special professional software can be used to set visit password, set each channel to stop/close, input calibraiton value to each channel, close LED light for power saving, select sample format(average, immediate, Max and Min)
