Description

These absolute pressure gauges are used when the pressure measurement needs to be carried out independently of fluctuations in atmospheric pressure.

Based on the diaphragm element measurement principle, extremely low scale ranges from 0 ... 25 mbar absolute pressure are available. These measuring instruments, made entirely of stainless steel, are suitable for gaseous, liquid and aggressive media.

The instruments owe their high long-term stability and subsequent long service life to the special, extremely gas-tight material of the reference chamber. Thus, the required vacuum can be maintained in the reference chamber for a long time. A metal media chamber sealing also contributes to this.

For further approvals, see page 6

Absolute pressure gauge, model 532.52

In addition, depending on the scale range, this instrument features an overload safety of at least 1 bar absolute pressure. Depending on the version, the overload safety can be up to 20 times the full scale value, but a maximum of 25 bar absolute pressure.

The qualification and production of the instruments is carried out in accordance with DIN 16002, which was developed with the cooperation of WIKA.

The QR code on the dial allows instrument-specific information such as the serial number, the order number, certificates and other product data to be retrieved from the internet easily and in the long term.
