Analog channels can be transmitted using either a timed mode or <br />and event mode. <br /> <br />Timed transmissions can be sent at intervals ranging from every 3.6 minutes <br />to 12 hours. At each interval, a message is transmitted. <br /> <br />In event mode, messages are transmitted only when sensor status has <br />changed. Every 3.6 minutes sensor status is checked. If no change has <br />occurred, no message is sent. If a change has occurred since the last <br />transmission. the measurement is sent. Battery power is conserved since <br />repeated reports of 'no change' are eliminated. <br /> <br />Event mode is very important in flash flood situations. When field <br />conditions are changing most rapidly, event mode provides the optimum <br />response. The data reporting rate automatically adjusts as conditions <br />intensify. Rapid sensor changes cause the most frequent and timely data <br />reporting. <br /> <br />5050 Specifications <br />Size. 8 in. dia. x 22 in, <br />Weight, 9 lbs without battery. 17 lbs with battery <br />Battery 9.5 amp .hour, 12 VDC. 8 lbs. <br />Standby current: 100 microamps <br />Transmission current.

Binary <br /> <br />5090SA STANDPIPE ASSEMBLY The ten foot tall 5090 standpipe assembly <br />serves as the housing for the 5050 transmitter and as the support structure <br />for the 5050ANT omni antenna. Light weight aluminum is used to form the <br />sturdy 12 inch diameter standpipe that is easy to transport and install in <br />remote areas. <br /> <br />The standpipe can be located up to 1000 feet from the 5050LL-PT sensor <br />site. This allows you to locate the 5090SA for optimum protection from <br />potentially damaging debris flows. from vandals. and for improved radio <br />paths. <br /> <br />Forest green or a dull brown paint helps the 5090SA blend in with the <br />surrounding vegetation and terrain. <br />
