A 15 O +_ 5 O 45 O This dimension applies when tap drill cannot pass through entire boss. 011 / Notes: 1 Threads machined per ANSI/ASME B The threads should be machined to meet the strength requirements of the material. 3 The port is similar to SAE J1926/1 port 3/4-16 UNF-3B hole #8 with dimensional changes. Micropulse transducers are available with a ¾ x 16-UNF (optional M18 x 1.5) mounting thread. Sealing is accomplished at the flange mounting surface using the supplied O-ring. If the transducer is to be mounted into magnetizable material, non-ferrous spacers should be used, as shown in the diagram above.

5 Setting Interrogation Mode and Recirculation Count The procedure below can be used to adjust the number of recirculations applied to the pulse-width-modulated gate output pulse. The number of recirculations is factory set, but can be changed in the field if necessary. In addition, it is possible to set the interrogation mode (INTERNAL or EXTERNAL). Step 1: Using a 3 mm hex wrench, loosen and remove the two electronics housing screws. Step 2: Carefully pull the electronics head no more than 2 away from the flange of the pressure tube. Take care not to twist or otherwise damage the flexband connecting the electronics head to the sensing element Interrogation Mode OFF OFF OFF External Interrogation OFF OFF ON Internal Interrogation, 2 ms Update OFF ON OFF Internal Interrogation, 4 ms Update OFF ON ON Internal Interrogation, 8 ms Update ON OFF OFF Internal Interrogation, 12 ms Update ON OFF ON Internal Interrogation, 16 ms Update ON ON OFF Internal Interrogation, 20 ms Update ON ON ON Internal Interrogation, 24 ms Update Recirculation Count Step 3: Locate the 6-position DIP-switch located on the edge of the printed circuit board. Using the chart at right, set the DIPswitches for the desired interrogation mode and recirculation count. OFF OFF OFF 1 OFF OFF ON 2 OFF ON OFF 3 OFF ON ON 4 ON OFF OFF 6 ON OFF ON 8 ON ON OFF 10 ON ON ON 5 Step 4, Reassembly: Carefully slide the electronics head back into place on the pressure tube assembly, being careful not to pinch the flexband. Apply a small amount of thread-locking compound to the two hex screws and tighten to maximum 2 ft.-lbs. using a 3 mm hex wrench.
