Product Description

WIKA  113.53  is a liquid‑filled Bourdon tube pressure gauge with a stainless steel case and copper alloy wetted parts, designed for  industrial applications with vibration and pressure pulsations. Manufactured to EN 837‑1 / ASME B40.100 standards, it  offers reliable performance, high safety, and long service life in demanding environments.

Key Features

1.Liquid‑Filled (Glycerin)

Excellent vibration & shock resistance, stable pointer reading under pulsating pressure.

2.Stainless Steel Case (IP65)

Dust‑tight and water‑protected, suitable for harsh industrial conditions.

3.Copper Alloy Bourdon Tube

C‑type or spiral tube for gas/liquid media that do not attack copper alloy.

4.High Safety Design

Built‑in blow‑out back safely releases overpressure in case of failure.

5.Accuracy Class 2.5

±2.5% of full span; optional Class 1.6 available.

6.Wide Pressure Ranges

NS40 (1.5"): 0…0.1 MPa to 0…40 MPa

NS80/100 (3"/4"): 0…0.1 MPa to 0…60 MPa.

7.Standard Sizes

40 mm (1.5"), 80 mm (3"), 100 mm (4") dial diameters.

8.Temperature Range

Ambient: ‑20°C … +60°C

Medium: max +60°C.

Applications

• Hydraulic systems / Hydraulic power units.

• Compressors & pneumatic systems.

• Machine tools & general machinery.
