100 μA is not necessary. The LAMBRECHT data logger TROPOS is equipped with such a bounce-free input. Thus the direct output signal of the pre- cipitation sensors can be used. An additional benefit is a low- current effect.
Operating Instructions Precipitation Sensors (15188)+(15188 H) Initial operation If the sensor system has been completely mounted and electrically assembled, the sensor will be ready for opera- tion. The operational check has to be performed. Maintenance and operational check The precipitation sensor is nearly maintenance-free. The...
