About the PCA-375-PR 020 - Compact AC Gage Head
The PCA-375 PR-020 gage head is an ultra-compact device that provides accurate measurement in areas with limited space. Utilizing a radial cable exit, the slim, low profile of the PCA-375 PR-020 easily fits within miniature fixtures and small inside diameters. With the time proven reliability of its LVDT (Linear Variable Differential Transformer) and measuring just 0.375 inch [9.5mm] in diameter the PCA-375 PR-020 affords non-intrusive, slim profile measurements, making it the perfect choice for high density fixtures as well as numerous other industrial applications.
Externally, the PCA-375 PR-020 is constructed of 300 Series stainless steel, with a field replaceable chrome plated hardened tool steel contact tip. Internally, the LVDT, along with a permanently lubricated bronze bearing and plunger assembly, provide long term repeatability and reliability. Electrical termination is via a 2 meter long, 6 conductor, shielded polyurethane jacketed cable.
Like in most of our LVDTs, the PCA-375 PR-020 windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a two-component epoxy. This provides excellent protection against hostile environments such as high humidity, vibration and shock.
Designed to service applications with limited space availability, the PCA-375 PR-020 is ideal for bore gages, or in practically any location where space is at a premium. Available with optional pre-wired connectors, and a variety of replaceable contact tips, it can be installed directly into standard AGD dial indicator mounting hardware without modification, affording maximum versatility.
