Pressure 7 bar Order Codes: High in Air Sensors: Output Voltage in Liquid < 1Vdc; Output Voltage in Air is within Vs - 0.5Vdc 3 Wire 4 Wire (2) D500D3 D500D4 Low in Air Sensors: Output Voltage in Liquid is within Vs - 0.5VDC; Output Voltage in Air < 1Vdc 3 Wire 4 Wire (2) (1) (2) D500D3L D500D4L Plastic Nut LLPK3 must be ordered separately. In certain applications (when used in certain liquids or emulsions and in heavily condensing applications), it may be necessary to “tune” the sensor’s operation using a 4th wire connected directly to the LED. This requires the installer to select a suitable current limiting resistor— Drawing dimensions in millimetres American Electronic Components Inc., 1101 Lafayette Street, Elkhart, Indiana.
