| It’s surprising that there are so many units of measure. It’s actually surprising there are not more problems than there are.
Here at Homershams we have to deal with thread sizes and types; e.g. 1/4″ BSP, 1/2″ BSP Parallel and NPT. In temperature probes someti |
Differential pressure as the name implies, is a reading of the difference between 2 pressures.
Hence a differential instrument will always have two inputs. A differential instrument can be used to measure ‘gauge’ pressure by opening one port to the air such that the pressure on the second port is re… Read more
Often we see pressure instruments coming into our laboratory for calibration with damaged threads. In some cases it’s clear that there has been a mismatch in process connection to instrument.
We felt it might be helpful to summarize the thread types that are available.
