TGRF4904, Tinytag Plus Radio Data Logger with 4 Pulse Counting Inputs
TGRF4904, 4-Channel Radio Data Logger for Pulse CountingThe TGRF-4901 is a count logger with four inputs, recording 0 to 32,000 counts per interval.
The data logger is waterproof and suitable for outdoor, industrial and warehousing applications.
It can be connected to a variety of different voltage-free and digital third party sensors to record properties such as pressure, flow rates and footfall.
- Flow rate of liquids and gases
- Conveyor belt monitoring
- People counting
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
This logger can be connected to sensors of other manufacturers via the four supplied current/millivolt/count input lead or via optional 2-pin plugs ACS-9700.
