3.4 Connecting sensor to EDAS-10 data acquisition system
Model EAN-90M tilt meter requires external power source of ± 12V DC (regulated) when connected to
EDAS-10 data acquisition system. For connecting tilt meter, a multiplexer model EAM-616 is required. 16
tilt meters can be connected to each multiplexer model EAM-616.
Maximum input of EDAS-10 is ± 2.5 V; whereas output of tilt meter is ± 4 V at 15
0
proportional to Sin of
angle. A high precision attenuator is therefore required as shown in diagram below:
Use EDAS-10 function P2 to read output of tilt sensor in terms of 0.5 volts. The multiplier and offset should
be kept as 1 and 0 respectively. To get tilt angle refer to typical gage factor and formula given in relevant
test certificate. A sample test certificate for uni-axial sensor can be referred to in section 3.5.
