Precautions Relating to the Use of the Fujikura Oxygen Sensor Carefully read the following before using the oxygen sensor and analyzer. 1. Applications for medical appliances, life-support equipment and low oxygen detectors Fujikura products are not designed, intended or approved for use as components of surgical or life support systems, or other applications that may cause injury or death as a result. In unapproved applications or uses where the customer implies, directly or indirectly, resultant injuries or deaths are due to Fujikura, Fujikura affiliates and agencies (citing for example, a...

Operational precautions Measurement of atmospheric gases Calibration gas The sensor should be adjusted with a calibration gas that is a mixture of nitrogen, N2 (or Argon, Ar) and oxygen, O2. Other balance gases may result in incorrect measurements. Combustible gases An atmosphere continuing combustible gases such as methane, alcohol, hydrogen and carbon monoxide may cause errors in measurement. Since the sensor element functions at 450°C, gases that ignite below that temperature must not be sued. Silicon gases Never use silicon gases containing siloxane, as these gases react with the sensor and...

Operating conditions Dust and oil mist Employ a filter system to eliminate dust and oil mists that clog the sensor and analyzer filter, resulting in problems, measurement errors and incorrect responses. Water and condensation moisture Contact of the sensor with water may destroy the sensor. system. Exclude water from the There is a risk to burns, since the sensor mesh is heated to 50 - 80°C while the sensor is in operation. Do not subject the sensor to a shock of 10G or greater which may cause breaks in the wiring and cracks in the sensor chip. The sensor element is made of a ceramic material....
