PT. SRIAYU MULTI KREASI

Pressure Gauge WIKA 733.18


APPLICATION

  • Measurement of differential pressure or of two different pressures applied in refrigeration plants or compressors
  • Simultaneous measurement of the vapour pressure and the resulting vapour temperature
  • For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive ambience

SPECIAL FEATURES

  • Differential pressure with moving dial
  • Design optionally with duplex scale
  • With liquid-filled case for damping in applications with high dynamic pressure loads or vibrations and for avoiding condensation water
  • Combined pressure and temperature scales, as duplex, triplex or quadruple scales for all common refrigerants

DESCRIPTION PRODUCT

Design

Two independent measuring systems, parallel entries in line

Nominal size in mm

80, 100

Accuracy class

1.6

Scale ranges

0 … 2.5 to 0 … 60 bar -1 … 0 … +25 bar

-1 … 0 … +12 bar -1 … 0 … +30 bar

-1 … 0 … +15 bar -1 … 0 … +35 bar

-1 … 0 … +16 bar -1 … 0 … +40 bar

Other scale ranges on request

In order to ensure a good readability, the differential pressure should be no less than

1/6 of the full scale value.

Pressure limitation

Steady: Full scale value

Fluctuating: 0.9 x full scale value

Short time: 1.3 x full scale value

Permissible temperature

Ambient: 0 … +60 °C

Medium: +100 °C maximum

Temperature effect

When the temperature of the measuring system deviate from the reference temperature

(+20 °C): max. ±0.4 %/10 K of full scale value
