Page 5: Introduction
The Percent Oxygen Transmitter is equipped with two oxygen analysis ranges, 0–25% and 0–20.9% (air calibration range). The Model 300P is approved by Factory Mutual (FM) as intrinsically safe for opera- tion in Class 1, Division 1, Groups A, B, C, and D hazardous environ- ments. -
Page 6: Typical Applications
Compact size, easy to install Typical Applications The Model 300P Percent Oxygen Transmitter is capable of monitor- ing oxygen at the % level in a variety of gases. It is widely used in indus- try. A few typical applications are: •... -

Page 8: Circuit Description
(See Appendix - Material Safety Data Sheet (MSDS)). Circuit Description The 300P circuitry consists of four stages: an input stage, a tempera- ture compensation/ gain stage, a low-pass filter and an output voltage-to- current stage. The output of the O cell is a current directly proportional to the amount of oxygen present. -

). This is about 2 nA per ppm. RFI Protection The Model 300P is designed to be RFI protected by virtue of the electronics being mounted inside a grounded metallic enclosure. The RFI protection, therefore, is maximized when the enclosure door is closed. - Page 10 2 2 2 2 2 Operational Theory Model 300P Teledyne Analytical Instruments...

NOTE: Do not disturb the integrity of the cell package until the cell is to actually be used. If the cell package is punctured and air is permit- ted to enter, the useful life of the cell will be adversely affected. Teledyne Analytical Instruments... -
Page 16: Cell Warranty
Press up on the cap and rotate until it threads. Tighten the cap. Cell Warranty The Class B-1 cell employed in the Model 300P is warranted for six months of service. Other special cells may be used on occasion, depending upon the application. - Page 17 If it is determined that failure is due to faulty workmanship or material, the cell will be replaced at no cost to the cus- tomer. NOTE: Evidence of damage due to tampering or mishandling will render the cell warranty null and void. Teledyne Analytical Instruments...
