Spectron Glass and Electronics Inc. Dual Axis Angle Threshold Detector SSY0187

The SSY0187 is a dual axis threshold angle detector with adjustable hysteresis angles and delay time. There are five open collector outputs. The two outputs for the Pitch angle (plus & minus) and two outputs for the Roll angle (plus & minus) indicate when the threshold angles have been exceeded (Transistor on). Outputs will automatically reset when the unit is tilted back within the threshold angle minus the hysteresis angle. The other collector is used to indicate two different functions. When the jumper is connected between the common and the mechanical null position (see Figure 3) the output will indicate that the unit is at mechanical null with respect to gravity. When the jumper is connected between the common and the position null, the output will indicate that the unit is within the set threshold limits in both the pitch and roll axes. Four potentiometers are provided to set the pitch and roll thresholds, hysteresis, and delay time. The hysteresisfunction allows the user to expand the threshold angle as the unit is reset when returned to null. The delay function provides filtering of false signals resulting from shock or vibration. Setting can be either factory adjusted and or set by the user.
