Output range
• De„nes the measuring range of the sensor
Output clamp levels
• Limit the pressure output signal if the pressure rises above or falls below the normal range
Sensor fault signal
• Placed below the pressure output range. Output at this level signals a sensor fault
Harness fault detection
•Low leakage current of the sensor allows the controller to recognize harness fault conditons. (Requires a pulldown or pull-up resistor at controller interface).
If the connected controller has an internal pull up or pull down resistor at the analog channel input, then the loss of ground or supply voltage (Vss) connection to the sensor will result in a near Vss or near ground signal voltage.
