PRODUCT INFORMATION

Structure and Dimensions:

Basic Measuring Circuit:

REV: 09/16

The sensor requires two voltage

pins: Pin #3--heater (+), Pin #2--sensor

electrode (+), and Pin #1--common (-).

To maintain the sensing element at

specific temperatures which are optimal

for sensing two different gases, heater

voltage of 0.8V is applied continuously

between pins #1 and #3.
