Description

1.1 Description
LLD100 levee leakage detector transmitter main technology parameters are as follows:
1) Output frequency, output frequency stability (drift in 7 h) is be superior to 7 x 10-4.
2) Output voltage: maximum voltage amplitude is not less than 90 V. (peak-to-peak value)
3) Sending current: Maximum current is not less than 500 ma. (peak-to-peak value)
4) continuous working hours:
When the output current is 200 mA (peak-to-peak value), continuous working time is more than 10 h.
