We suggest that users of Pressure Note A. ll safety case styles are designated Gauges refer to American National DIAL SIZE by a number.

A glass face is standard in most gauges.

Consult corrosion chart on page 5 for proper selection of Pressure system materials. POINTER. Weksler models are offered with: All Weksler gauges (except utility types) have Phosphor bronze Bourdon tube (or bellows).

The ambient Temperature to which the gauge Monel Bourdon tubes with Monel sockets. will be subjected should not exceed 150 F. If higher temperatures are encountered the gauge For applications where the above materials must be isolated from the source of heat.

CASE. A wide variety of case styles and materials are offered. Determine how the gauge is to be mounted: direct, surface (wall) or flush (in panel). Determine the desired case materials: polyproylene (or phenol); aluminum (black enameled) or stainless steel (300 series). Determine case type: 4. 5.
