Sensor
Removing the sensor
1. Remove the top cover from the analyzer.
2. Remove the cover from the oven assembly. Facing the front of the
Model 3050 RM analyzer, the sensor is the small PC board with two
metal cans in the center of the sample manifold plate (Figure 8-2).
3. Disconnect the two 1/16” fittings that connect the sensor to the stream
switching valve manifold in the center of the sample manifold plate
(Figure 8-3).
4. Lift the sensor assembly from the oven compartment being careful
to free the ribbon cable attached to it from the other wires that pass
through to the electronics compartment.
5. Disconnect the ribbon cable from the analog interface board and dis-
card the old sensor.
Installing the sensor
1. Mount the new sensor on the stream switching valve manifold by
carefully inserting and tightening the two 1/16” fittings.
2. Run the ribbon cable from the sensor through the slotted opening in
the oven wall into the electronics compartment.
3. Connect the ribbon cable plug to position P2 on the analog interface
board (Figure 8-10).
4. Replace the oven lid and secure it with the two nuts.
5. Replace the analyzer cover and secure it with the mounting screws.
Use caution when disconnecting the moisture generator and pressure
transducer from the sample system. The tubes are delicate and care
should be taken not to transfer torque to them.
