12 Load sensor adjustment
12.1 KAE400 + Strain Gauge
12.1.1 General
KAE400 is a amplifier which is used to amplify the strain gauge load sensor signal (mV) to higher level
(V). Both full bridge and half bridge sensors can be connected. Amplifier has zero adjustment with led
indication and two-fixed gain (160/400).
12.1.2 Technical data
Operation voltage (Vsup) 9,5...12 VDC (maximum ratings)
Sensor supply voltage (Vssup) Vsup-0,5 VDC
Gain (set by a switch) 160 / 400
Zero adjustment -10…+10 mV (350R measuring elements)
-30...+30 mV (1k measuring elements)
Output voltage at 0 mV input 2,048 VDC
Minimum output load 10 kohm
Operation temperature -25…+85° C
Wire brakage monitoring OUT: < 0,5VDC or > 8,0 VDC
EMC standards EN61000-6-2 , EN61000-6-3
