New pressure gauge isolator improves accuracy

The patent pending Ashcroft AccuSeal gauge isolator from Dresser Instruments eliminates the additional 1/2% error that normally results from adding a diaphragm seal to a digital pressure gauge

Adding a diaphragm seal to a digital gauge generally results in a loss of 1/2% accuracy or more due to liquid fill error that occurs between the gauge and the seal.

The patent pending Ashcroft AccuSeal gauge isolator from Dresser Instruments eliminates the additional 1/2% error.

The AccuSeal gauge isolator has a unique design that uses a sensor diaphragm to isolate the media and prevent it from clogging the gauge.

This sensor is almost flush with the bottom of the gauge socket.

The sensor diaphragm is 17-4 stainless steel with a 316 stainless steel process connection.

As one self-contained unit, it takes up less space than a conventional gauge and seal assembly and can be used with any seal configuration where the process is compatible with 17-4 stainless steel.

AccuSeal is available from UK Instruments and Controls, on Ashcroft 4.5" digital industrial gauges (models 2074, 2174 and 2274) with 1/2" NPT process connections.
