Sensor Information

 

 

The Sensor Information page displays information on the following:

• AVdd: This value is the supply voltage for the analog to digital converter that measures the pellistor voltage. This value is typically about 5V.

• Excitation Vdd: This value is the voltage seen across the pellistor bridge. This value should be approximately 0.9V.

• Pellistor Vdd: This value is the voltage present across the sensing pellistor. This voltage, in air, should be approximately half the excitation voltage.

• Gas Temperature: The temperature of the measured gas

• Ambient Temperature: The ambient temperature where the sensor is located.

NOTE: The following options are intended primarily for SSi personnel to assist with troubleshooting procedures.

• Zero Vdc: (voltage direct current) A record of the zero vdc reading from the most recent calibration. 

• Zero Gas Temperature: A record of the zero gas temperature reading from the most recent calibration.

• Span Vdc: (voltage direct current) A record of the span vdc reading from the most recent calibration.

• Span Gas Temperature: A record of the span gas temperature reading from the most recent calibration.

• Span Target %: A record of the span target % from the most recent calibration.

 

Note that each of these values is for diagnostic use only. Call SSi at (513) 772-0060 with questions.
