113.13 WIKA liquid-filled hydraulic pressure gauge

Description

113.13 The WIKA liquid-filled hydraulic manometer is used for pressure measurement of gaseous and liquid media.

The Hydraulic Pressure Gauge model 113.13 is a liquid-filled mechanical pressure gauge with a plastic casing.

The liquid filling causes damping of the internal components and contributes to greater resistance to vibration and shock.

Hydraulic pressure gauges are suitable for installation in machines and plants where vibrations and shocks are expected.

These hydraulic gauges are based on the proven Bourdon gauging system. The deflection of the Bourdon tube is transferred to the movement and displayed.

The plastic housing and window are welded together, and an O-ring seals the process fitting on the housing. In this way, the instrument meets the high ingress protection requirements of IP65.

With an accuracy class of 2.5 and available nominal sizes 40, 50 and 63, this model is suitable for a wide range of industrial applications. The mounting bracket, available as an accessory, allows the pressure gauges to be mounted on a plate with a rear-mounting connector. The 63 mm nominal size version with a mounting connector on the back is also available with a mounting flange on the front of the instrument. This fixing flange is used when, for example, the panel can only be fixed from the front.
