Model 732.18, 733.18 Differential Pressure Gauge
Brand: WIKA Alexander Wiegand SE & Co. KGFor refrigeration technology, stainless steel, NS 80 and 100.
Features- Differetial pressure with moving dial.
- Design optionally with duplex scale.
- With liquid-filled case for damping in applications with high dynamic pressure pulsations or vibrations and for avoiding condensation water Model 733.18.
- Combined pressure and temperature scales as duplex, triples or quadruplex scales for all common refrigerants.

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° to +60° C
- Medium: +100° C Max.
Temperature Effect
- When the temperature of the measuring system deviates from the reference temperature (+20° C): Max. ± 0.4 %/10 K of Full Scale Value
- 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
