1.6.1 Oxygen Sensor and Protection Cap Diagram
All sensors include a screw-on protection cap, available in one of three
configurations. The standard protection cap, model 29104, provides improved
membrane sealing. The other configurations, for “Moist Gases” (model 29107)
and for “Liquids and Dry Gas Samples” (model 29106) also include a stainless
steel grill and either a Dacron mesh or water separation filter. The grill prevents the
membrane from lifting under such harsh conditions as high sample pressures, or
measuring in carbonated samples.
