DESCRIPTION

SPECIFICATIONS

The Model 1981 and 1981 Advantage 4-1/2" process
gauges have all 316L stainless steel wetted surfaces
with a seamless Bourdon tube. The 1981 Advantage
includes a dampened movement option to provide
users with some of the benefits of liquid filling. These
gauges have a PET turret style case for chemical and
petrochemical processing applications. The PET material
gives this case superior impact strength and a broad
spectrum of chemical resistance. They are available
dry, with a dampened movement, or liquid filled from
the factory. Your local stocking distributor can provide a
liquid fill kit, or the E-Z Fill design to facilitate filling in the
field without special tools.
