WIKA Models 611.10, 631.10 Capsule pressure gauge, copper alloy or stainless steel Standard version, NS 50, and 63

• Designed for use in severe industrial
and hydraulic environments
• Resistant to cavitation, liquid hammer
and pressure peaks (MBS 3050)
• Enslosure and wetted parts of acid-resistant
stainless steel (AISI 316L)
• Pressure ranges in relative (gauge)
or absolute from 0 up to 600 bar
• All standard output signals:
4 – 20 mA, 0 – 5 V, 1 – 5 V, 1 – 6 V, 0 – 10 V,
1 – 10 V
• A wide range of pressure and electrical
connections
• Temperature compensated and laser calibrated
• For use in zone 2 explosive atmospheres

Highly developed sensor technology means high
pressure regulation accuracy, a very important
factor in the precise and energy-economic capacity regulation of refrigeration plant.
ƒ Temperature compensation for LP and HP
pressure transmitters, developed specially for
refrigeration plant:
LP: −30 → +40°C (≤16 bar)
HP: 0 → +80°C (>16 bar)
ƒ Compatibility with all refrigerants incl. ammonia means less stock and greater application
flexibility.
ƒ Built-in voltage stabiliser, i.e. the AKS pressure
transmitters can be powered from an unregulated voltage supply of any output within
given limits.
ƒ Effective protection against moisture means
that the sensor can be mounted in very harsh
environments, e.g. in the suction line encapsulated in an ice block.
ƒ Robust construction gives protection against
mechanical influences such as shock, vibration and pressure surge. AKS sensors can be
mounted direct on to the plant.
ƒ No adjustment necessary. With the highly developed sensor technology and sealed gauge
principle, the accuracy of the factory setting is
maintained independent of variations in ambient temperature and atmospheric pressure.
This is very important when ensuring evaporating pressure control in air conditioning and
refrigeration applications.
ƒ EMC protection according to EU
EMC-directive (CE-marked)
ƒ UL approved
ƒ Polarity protected inputs.
