Flame arrester protects sewage vacuum truck tanks
| Jing Lyu | ApplicationsA pre-volume deflagration flame arrester or – simplified – a flame arrester prevents flame transmission, through a measuring instrument, into a zone 0 (gas) hazardous area. This protective function, therefore, plays an important role, especially in process …
Calibration of ultra-high pressures over the entire measuring range
| Jing Lyu | ApplicationsThe calibration of ultra-high pressures is a challenge. This is because conventional test instruments are only designed for pressures up to 1,000 bar. In many applications, however, sensors work with several times this value, for example in the automotive industry. If …
Switch with “CCC Ex” for the Chinese market
| Iris Benkstein | Know-howCCC - without proof of China Compulsory Certification, many industrial goods are denied access to the "Middle Kingdom". Since 1st October 2020, this compulsory marking has also extended to products with explosion protection. Therefore, all WIKA instruments that fall …
Safe filter monitoring with differential pressure gauges
| Jing Lyu | ApplicationsFilter monitoring is a core task of differential pressure gauges - the differential pressure increases as soon as the filter becomes clogged. The measuring instruments thus signal when the filter needs to be cleaned or replaced. The efficiency of such a solution can be …
