Original Press Release:

A New Ashcroft® Solution for Processes that Clog

The entrapment of solids in the pockets of instrumentation directly affects the performance of pressure measuring devices. The new Ashcroft® Type 330 mini-diaphragm seal meets this challenge head-on with a diaphragm that is flush with the end of the 1" male NPT process connection. By eliminating any pocket or dead-leg, particles in the process will not interfere with continuous instrument performance.

Because of its design, the diaphragm of the Ashcroft® 330 seal can be easily cleaned. This is ideal in applications like paint booths where the process media changes.

The Ashcroft® Type 330 seal has an all-welded construction to prevent leakage of the process media and a 316L stainless steel top housing and diaphragm. It is compatible for use with switches, transducers, digital gauges or analog pressure gauges from 60 through 1000 psi; and is offered with a variety of fill-fluid.

The Ashcroft® 330 seal has a two week lead time or is available in five working days with the Ashcroft® Gold ServiceSM option. Customers have the unique opportunity to order this or any Ashcroft® diaphragm seal with an instrument attached, directly from Dresser Instruments' factory.
