Description
The models 614.11 and 634.11 capsule pressure gauges are based upon the proven capsule measuring system. The capsule element measurement principle is suitable for very low pressures. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated.
The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges.
Special features
- Panel mounting with dimensions per DIN IEC 61554 from 72 x 72 mm [2.84 x 2.84"] to 144 x 144 mm [5.67 x 5.67"]
- Low scale ranges from 0 ... 2.5 mbar to 0 ... 600 mbar or 0 ... 1 inH 2 O to 0 ... 240 inH 2 O
- Zero point setting possible
