Accurate slide gate position feedback when then the gate movement from fully closed to fully open position extends an arc of a minimum of 5.6º or a maximum of 130º of the SG1000B
The SG1000B has three calibration points
A mid-span position where the telescopic arm is perpendicular to the linear direction of travel.
The 4 mA point is when the arm is at the 0º or gate fully-closed position
The 20 mA point is the fully-open position. The distance between the fully-closed and fully-open positions can be as small as a 5.6º swing of the telescopic arm, or as large as a 130º swing of the telescopic arm
