Gauge isolator improves seal accuracy
Dresser Instruments, Stratford, Conn.
|
Liquid fill error that occurs between
a digital gauge and diaphragm seal can result in a loss of 0.5 percent
accuracy. A sensor diaphragm in the Ashcroft AccuSeal gauge isolator that
is almost flush with the bottom of the gauge socket isolates media to
prevent clogging. This eliminates error, the company says. The 17-4
stainless-steel sensor diaphragm has a 316 stainless-steel process
connector and occupies less space than traditional gauge-and-seal
assemblies.
