Model 232.50 / 233.50 Bourdon Tube Pressure Gauge

Brand: WIKA Instruments
This high-quality Bourdon tube pressure gauge has been designed especially for the process industry. 

The use of high-quality stainless steel materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments. 

Scale ranges of 0 - 0.6 to 0 -1,600 bar [0 -10 to 0 - 20,000 psi] ensure the measuring ranges required for a wide variety of applications. 

WIKA manufactures and qualifies the pressure gauge in accordance with the standards EN 837-1 and ASME B40.100. As a safety function, this instrument has a blow-out device with blow-out plug on the back of the case. In the event of a failure, overpressure can escape there. 

The model 233.50 with liquid-filled case is suitable for high dynamic pressure loads and vibrations.
Features
  • Excellent load-cycle stability and shock resistance
  • All stainless steel construction
  • Positive pressure ranges to 20,000 psi (1.600 bar)
