GPR-18
The advantages of the bypass sample system include:
¾ Supplying the analyzer with the sensor it was qualified with.
¾ Isolating the sensor during transport, calibration and maintenance intervals when changing gas line connections.
¾ Isolating the sensor from exposure to high oxygen levels during upset conditions which extends sensor life.
¾ Purging the air (or high oxygen levels above 1,000 ppm) trapped in the gas lines following a process upset.
GPR-28 is designed with a sample system that enables the user to control the flow rate via a flow meter positioned upstream
of the sensor. The sample must be properly presented to the sensor to ensure an accurate measurement. The sensor is
exposed to sample gas that must flow or be drawn through the analyzer’s internal sample system.
