Description

The Model 213.53 liquid-filled Bourdon tube pressure gauge features a stainless steel case and copper alloy wetted parts, manufactured to EN 837-1 and ASME B40.100 standards. Its liquid-filled case provides excellent damping against high vibrations and dynamic loads, while a built-in blow-out device ensures safety under overpressure conditions. Available in nominal sizes of 50, 63, and 100 mm with IP65 protection and up to Class 1.0 accuracy, it is highly versatile for industrial applications and offers various panel mounting options for easy installation.
