Pharmaceutical

The pharmaceutical industry operates in an environment with strict requirements on safety, sterility and accuracy. In the manufacture of pharmaceutical products, medicaments and high-purity water – IPTech sensors are reliable and easy to clean.

Applications

Bioreactor

Level and pressure measurement in the production of enzymes, proteins and antibodies

Application

Some pharmaceutical companies use bioreactor vessels to cultivate particular cells or microorganisms required for certain treatments. The very high level of hygiene required means the vessels and all associated parts must be easy to thoroughly clean, because even the slightest contamination with other organisms can lead to an aborted production run. These reactors are mainly “batch-fed”, where they are completely filled at the start and not emptied again until the process is completed. The pressure and level in the reactor have to be monitored continuously during process in order to obtain a high-quality yield.

Filter system

Differential pressure measurement for filter monitoring

Application

Often, in the manufacture of pharmaceuticals, substances need to be separated from one another or perhaps some cell components precipitated. One method of doing this is using special filtration systems. When the filter is working properly, the quality and yield of the products are at their optimum. So continuous differential pressure monitoring of the filters ensures the filters are running at their most efficient at all times.

Batching tank for ointments

Level and pressure measurement and point level detection in ointment production in batch mode

Application

Many different ointments and creams are produced in batching tanks. The process conditions in batch production are typically characterized by high temperatures and vacuum. After each batch run, the tank needs to be cleaned quickly and effectively with chemically aggressive cleaning agents ready for the next batch. Contamination of the products during the mixing or reaction process is prevented by the use of a protective gas atmosphere. To ensure a safe, reliable process, both the level and the gas head pressure must be continuously monitored.

Fluidized bed reactor

Level measurement and filter monitoring in granulate production in the fluidized bed process

Application

One method for producing and drying granulates is the fluidized bed process. A uniform stream of air is fed up through a distributor plate at the bottom of the fluidized bed reactor. A liquid granule suspension is sprayed in from above, in the air stream it turns into solid granulate and collects on the top of distributor plate and the exhaust air flows through a filter for cleaning. To ensure a high-quality process, both the granulate quantity on the distributor plate and the condition of the filter must be permanently monitored. The measurement technology must also fulfil the most stringent hygienic requirements in order to guarantee a consistently high granulate quality.
