TGRF-4743, 4-Channel Radio Logger for Low Voltage, 0-2.5VDC
The TGRF-4743 monitors four voltages from 0 to 2.5VDC and can be connected to a variety of sensors enabling the logging of a wide range of processes.
The data logger is waterproof and suitable for outdoor, industrial and warehousing applications.
Typical applications:For custom sensor monitoring, including:
- Pressure
- Flow rate
- Light
- Power (with a current clamp)
The logger will typically run for 12 months on its 2 AA alkaline batteries. (The 12 months operation is quoted for a typical 10 minute logging interval in a network with max. 25 radio loggers and at max. 25°C operational temperature).
If required the unit can also be powered by an optional mains power supply.
The unit is able to transmit logged data to another logger or a receiver and to store data locally in the event of radio contact being temporarily lost.
The data logger has got a status LED:
+ LED off: logger is off
+ green every 4 sec.: everything is o. k.
+ red every 4 sec.: not meshed or battery low or alarm indication
