Description
Overview
GAOTek thermistor temperature data logger is color paperless recorder for tft true color liquid crystal display, completely isolated universal input, such as thermocouple, thermal resistance, current voltage, temperature, liquid level, pressure, voltage, current, flow, vibration frequency input; adopt modularized structure to output alarm, sensor auxiliary power supply, forwarding, printing, communication and other functions. measurement data can be displayed in a variety of types, such as bar chart graphic display, real-time trend, historical trend memory, real-time circular chart, historical circular chart memory, alarm state display, etc. curves and data can also be printed by small printer through rs232 port. It also provides the function of viewing data of year, month, day, hour, minute, and second. The recorder can be configured with opc server, Scada system and other professional software, using modbus-rtu communication protocol through rs485 port. Historical data can be directly downloaded through the u disk, plug and play, convenient and flexible. The data analysis software supported by pc can print the data into curves and output them in excel format for further analysis.
