Automated Remote Temperature System (Wireless Temperature Sensor) is created for industrial monitoring systems and fridge transport fleets (trailers). It uses a wireless method and can work at a distance of up to 100 meters. The WTS consist of two modules: Transceiver and Receiver. The transceiver module has a power pack of 2 AAA batteries and can work for more than 1 Year without needing to change them. (The batteries lifetime depends directly on the ambient temperature). The receiver module is typically connected to a standard Fleet Management System (FMS).
TRANSCEIVER MODES:
Temperature: wirelessly transmits temperature to the receiver;
Door status: in this mode the system can monitor Door Status (open or closed);
Receiver power supply: 8-40 V;
1 - Wire interface to be easily connected to monitoring unit or FMS.
The receiver can support up to 4 transceivers.
