COMET SYSTEM, s.r.o
4G Wireless Temperature and Relative Humidity Datalogger with flood detector
he U3832G datalogger is used to measure temperature, relative humidity and dew point temperature using internal sensors, plus an attached LD-81 flood detector to indicate water flooding. In case of exceeded set limits, SMS and JSON messages can be sent via 4G data connection. Measured values can be sent to the internet storage COMET Cloud, which is a complete monitoring, alarm and analysis system.
It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD and acoustically by built-in beeper.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via included USB-C cable.
GSM recorder includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Web Sensor - two channel remote 0-20mA inputs to ethernet
Converter Web Sensor P2520 is designed for the connection of two sensors with current output into the Ethernet network. The measured
current (0-20mA or 4-20mA) can be converted to the physical quantity that is measured by the connected sensor. The converter is galvanically isolated from the Ethernet communication lines, current inputs and power supply are not galvanically isolated.
