Dynisco offers a set of mounting hole-machining tools with all the necessary drills, taps, and reamers
for the Dynisco standard ½-20UNF-2A and M18 and M10 mounting holes used in high temperature and
plastics processing applications (Dynisco Part Numbers 200925, 200105 and 901949 respectively).
Detailed instructions are sent with the machining kits. Copies of the instructions are available from
Dynisco upon request.
When machining the hole pay careful attention to the concentricity between the threads and the 0.312/
0.314 diameter. Since the pressure seal is on the 45
°
seating surface, this surface should be examined
for good finish, free from burrs, etc.
It is general good practice to check the mounting hole before installing the transducer. One procedure
is to coat a gauge plug (Dynisco Part Number 200908 for the 1/2 –20 standard port, 435901 for the
short tip 1/2 –20 version, 200960 for the M18), with Dykem machine bluing on surfaces below the
thread. Insert the gauge plug into the mounting hole and rotate until surface binding is encountered.
Remove and inspect. Bluing should only be scraped off of the 45
°
sealing chamfer. If bluing has been
removed from other surfaces, the mounting hole has not been machined properly.
