WIKA 342.11
WIKA 342.11 -Test Gauge – WIKA/Germany
- For gaseous and liquid media that are not highly viscous or crystallising
- Precision measurement in laboratories
- Highest-accuracy pressure measurement
- Testing and calibration of industrial type pressure gauges
- Knife edge pointer and dial with mirror band scale for optimal accuracy of reading
- Precise movement with wear parts of argentan
- Particularly easy-to-read scale due to nominal size 250
- Scale ranges up to 0 … 1,600 bar
Design
per EN 837-1, including transport case and acceptance test certificate (individual listing of the calibration points)
Nominal size in mm
250
Accuracy class
0.1: for scale ranges < 0 … 400 bar
0.25: for scale ranges ≥ 0 … 400 bar
Scale ranges
0 … 1.0 to 0 … 1,600 bar
or all other equivalent vacuum or combined pressure and vacuum ranges
Adjustment medium
≤ 25 bar: Gas
> 25 bar: Water
Pressure limitation
Steady: Full scale value
Fluctuating: 0.9 x full scale value
Permissible temperature
Ambient: -20 … +60 °C
Medium: +100 °C maximum
Temperature effect
When the temperature of the measuring system deviates from the reference temperature (+20 °C):
Max. ±0.1 %/10 K of full scale value
Ingress protection
IP54 per IEC/EN 60529
