2.1.2 Pressure method
There are three types of capacitive transmitters, as shown in Figure 2-4:

The pressure-receiving type of the piezoresistive transmitter is mainly a
screw connection method, and the user can provide a pressure-welded joint
according to the specific thread specification.
2.1.3 The process connection hole distance adjustment of
differential pressure transmitter
The process connection holes on the pressure chamber are 1/4-18 NPT.
These process connection holes require a thread seal. When using a waist
flange joint, the transmitter can be easily removed from the production unit by
simply removing the upper and lower bolts of the joint. The center distance
between the two process connection holes is 54 mm. Rotating the waist flange
joint, the center distance can be changed to 50.8 mm, 54 mm, 57.2 mm
