The TGT1 interfaced directly with our datalogger's CS I/O port. This transmitter supported U.S. transmission channels, and featured an output level of +40 dBm (10 Watts) and a transmission rate of 100 bits/second. Typically, 118 data points were transmitted during a 1-minute transmit window.Read More
The TGT1 had an average quiescent current drain of 9 mA and an active current drain of 2200 mA. The transmitter's forward/reflected power could be measured by the datalogger. A large reflected power indicated a possible problem in the equipment and Campbell Scientific should be contacted.
Typical power supply was a BP12 12-Ahr or BP24 24-Ahr battery, CH12R regulator, and a 10-watt solar panel. A user-supplied deep-cycle rechargeable battery was used when it was difficult to replace the batteries or the system's power requirements were large. The deep-cycle rechargeable battery should have at least a 60 Ahr capacity, and be trickle-charged with an 20 W solar panel.
The TGT1 was replaced by the SAT HDR GOES, which was replaced with the TX312.
