5.1.4Replacement of Transducers

Model 9816 has internal DH200 pneumatic transducers, as well as an internal calibration manifold with associated valves and O-rings. Some these elements occasionally require service or replacement as described in the following sections.

Following is a step-by-step procedure to replace a DH200 transducer in a Model 9816 Intelligent Pressure Scanner. Use the tools and follow the general warnings already described in Section 5.1.1.

(1)Disassemble the module as described in Section 5.1.2. Remove the transducer/cal-valve housing from the top chassis rail.

(2)Remove the PC-206 Amplifier/Multiplexer board as described in Section 5.1.3.1. Lay the circuit board aside on an anti-static surface.

(3)Remove the retaining screw from the desired DH200 transducer. Lift the transducer straight up to remove it. Make sure that the two (2) O-rings remain with the transducer as it is removed from the adapter plate. Ensure that the adapter plate O-ring sealing surface is clean and free of contaminants. See Figure 5.8.

(4)Replace the DH200, making sure that the electrical connections are located on the outer edge of the cubic design. Be sure that the two (2) O-rings are in place on the DH200 and that O-ring surfaces are free of contaminants. The O-rings should be lightly greased with Krytox® fluorinated grease. The DH200 must fit the guiding pins smoothly and be aligned with all other DH200 transducers. Tighten the retaining screw to 40 inch-ounces ±5 inch- ounces of torque.

Note	The hex-head standoff screws used on DH200 positions 2 and 15
	are used to secure the PC-206. These hex-head screws should not
	be over tightened or else the screw may break.
