Switch contacts make pressure gauges and thermometers “active”
Christoph Strebel | Know-howSwitch contacts in pressure gauges and mechanical thermometers significantly extend the functionality of the measuring instruments. They enable limit value monitoring in addition to on-site indication. Such instruments with switch contacts are therefore an important …
SIP in pharmaceutical processes: Sterilisation with ultrapure steam
Jing Lyu | Know-how“Sterilisation in place” or “steam in place”, SIP for short, is an indispensable process in pharmaceutical production. It involves sterilising the relevant process equipment directly in the plant using condensing steam. Following the cleaning in place (CIP) …
Pressure monitoring at high temperature is a challenge
Jing Lyu | ApplicationsPressure monitoring at high temperature is a demanding measuring requirement. This requires a specially designed diaphragm seal. With model 990.45, WIKA offers such an instrument in its portfolio and was therefore awarded the contract by the operator of an oil …
Coatings of measuring instruments: Use and advantages
Sina Odenwald | Know-howProcess applications are becoming increasingly complex. Measuring instruments must therefore meet the highest requirements and function reliably – even with harsh outdoor conditions or aggressive media. Coatings are usually indispensable for use, for example, in the …
