Performance Characteristics Optical Detection Elements…..………………………………………..4 Optical Sampling Frequency (1) ..……………………………………. 15 kHz Optical Detection Zone………………………………………………… 2mm Minimum Particle Detection Size .……………………………………. 1.5mm Minimum Optical Cross Section Coverage .………………………….40% Optical Calibration Steps (2).………………………………………….. 24 steps Note 1: 15kHz sampling frequency allows the detection of a 1.5mm seed particle at a velocity of 22.5 meters per second. Note 2: Calibration steps and range allow the sensor to adjust the optical intensity to compensate for foreign material build up on...

Diagnostic Data - Input Voltage - Micro Temperature - Regulated Voltage - Runtime timer - Detector bias levels - Detector calibration levels - Emitter current output - Software version - Hardware version - Sensor type Bidirectional communications allow for enhanced error detection and fault resistance. A single break or intermittent in the communication loop does not affect performance of the sensor loop because data can be rerouted in the reverse direction.
