Freeze-drying is a gentle, but technically complex drying process during which moisture is extracted from the frozen goods under vacuum conditions. So, many liquid active pharmaceutical ingredients for the pharmaceutical industry are quickly deep-frozen at temperatures of -70 to -100°C. Then, the frozen material is dried in a vacuum chamber. The ice evaporates at underpressure without becoming liquid - it sublimates. The water vapour is then extracted at increased vacuum and higher temperatures. For some types, the encapsulation of the glass bottles containing the ingredient is carried out under clean room conditions. Of all types of drying, freeze-drying leads to the least product changes and losses of ingredients. Freeze-dryers operate in 3 steps: freezing, main drying, final drying. As from the second step, a vacuum pump is connected to the drying chamber to initiate the sublimation. Here, extreme parameters are reached. The vacuum sensor must withstand 5 x 10-3 mbar. This means no external particles must enter into the drying chamber, as they would contaminate the product.

Pressure sensors have to withstand the extreme vacuum of 5 x 10-3 mbar. Tests in ifm electronic\'s test laboratory confirm that the ifm vacuum sensors meet these requirements.

The system pressure in a digested sludge pumping station is to be monitored and displayed on site. For visualisation and protocolling, the control room needs the measured value as an analogue signal. The pressure sensors need to have a robust design without complicated mechanical diaphragm seals. There must be no dead space on the sensor, as deposits could occur which may falsify the measured value.

The flush mountable pressure sensors of the PF series have been specially designed for use in viscous media and media which contain solids. No diaphragm seals are required. The flush ceramic-capacitive measuring cell prevents deposits. The parameters of the pressure sensor can be adapted to the plant control via a clearly structured menu.

Müşteriye sağladığı yararlar
The ifm pressure sensors of the PF series feature many functions in one unit: display of the process pressure, configurable switching outputs for limit value indication and an analogue output for remote transmission of the system pressure. The flush pressure measuring cell prevents deposits and ensures operation which is to a large extent maintenance-free.

The drift-free and long-term stable ceramic measuring cell of PY9000 does not require the, otherwise common, diaphragm seal. The patented tried-and-tested measuring cell support ensures long-term and reliable operation. Using the additional switching output of the sensor, an emergency switch-off can be triggered within just a few milliseconds when a predefined maximum pressure is exceeded.

Highly purified water is used for the production of computer chips and photovoltaic wafers as well as for the production and cleaning of ingredients in the pharmaceutical industry. This water has a minimal content of residual ions, organic parts and or bacteria count. The first production step is softening by means of the ion exchanger. The subsequent reverse osmosis removes up to 99 % of the ions and up to 99.9 % of the organic components in the water. Depending on the requirements for purity another processing step is carried out via a second reverse osmosis or electrochemical deionisation. The processed water is fed to a storage tank. The individual tap points are supplied via a ring line with continuous flow. To maintain microbiological purity, germs which may be present are rendered inactive via short-wave UV radiation upstream of the ring line.

In this process different sensors are used: Flow sensors ensure compliance with the required flow speed. Pressure sensors monitor the differential pressure of filters. The position of pneumatic diaphragm valves is monitored via safe feedback systems. As the cleaning or disinfection of a reverse osmosis system is carried out with aggressive media such as tensides, citric acid or peracetic acid, the condition of the valve diaphragms must be monitored.

By combining several treatment units the controller can generate a high degree of automation by means of the hygienic sensors used. As from reverse osmosis devices with calibration certificates of the manufacturer are standard. In this case for pressure and conductivity. An inspection certificate 3.1 is also required. Many different sensors can be obtained from one supplier. These sensors are normally fitted with a human machine interface and can be preset to the application. This is increasingly done via IO-Link.
