We have specialised in the measurement and monitoring of pressure and temperature, as well as derivable variables, like level and flow. Besides a wide...

KNOWLEDGE AND EXPERTISE HYGIENE REQUIREMENTS GIVING GERMS NO CHANCE EXCLUSIVELY FOR FOOD, PHARMACEUTICALS AND BIOTECHNOLOGY Strict national and international regulations govern products, which can directly or indirectly influence the health of humans. The requirements include the protection of health and environment, reproducible quality and traceability. Select the design and layout of the measuring equipment for reliable operation to ensure that components can be properly cleaned. Hygienic solutions are of key importance for users in these sectors. LABOM specifically produces special...

MEASURING TECHNOLOGY IN SENSITIVE ENVIRONMENTS

DESIGNING HYGIENIC PRESSURE AND TEMPERATURE MEASURING EQUIPMENT LABOM offers a whole range of solutions that meet “hygienic design” requirements to meet hygienic and aseptic demands. The equipment is compatible with Cleaning in Place (CIP) and Sterilisation in Place (SIP) cycles. The selection of materials, the design of measuring equipment, its production and installation in manufacturing facilities is optimised and tailored to the respective application. KEY MEASURES: ◼◼ Avoidance of constructive dead zones, gaps and edges ◼◼ Flawless surfaces with minimal roughness ◼◼ Flush-mounted...

SMOOTH SURFACES The structure and roughness of a surface is a crucial factor in the cleaning of dirt and micro-organisms. Only a flawless surface without scratches, pores, fissures and cracks can be cleaned and sterilised by automated processes. Our laser welds have generally a low roughness. Usually, an average of Ra  0.8 μm is sufficient <  on smooth surfaces and in weld areas. It is hard to achieve improved cleanability at roughness values below Ra  0.4 µm. The wetted areas =  of LABOM equipment are supplied with the adjacent surface roughness classes. Poor cleanability Enhanced...

NO GAPS AND EDGES The design makes the difference: In attempting to ensure that systems and equipment meet the purpose for which they were originally designed, it must be accepted that hygienic necessities can sometimes come into conflict with hygienic requirements. There should be no gaps and edges, but, at the same time, the equipment has to work perfectly. Hygiene safety always has priority in the search for an acceptable compromise. LABOM has a lot of experience in the process industry and offers a range of different hygienic or aseptic process connections. FEATURES OF ASEPTIC PROCESS...

NO DEAD ZONES Dead zones are produced by abrupt changes in diameter or the ends of blind pipes, among other things. Hygienic design of measuring points should aim to avoid dead zones, as they can lead to problems during cleaning. Basically the rule is: The higher the flow rate of a cleaning agent, the better the result. HOW DEAD ZONES ARE PRODUCED Diameter increases Diameter narrows Blind pipe end Improved solutions have to be found for the local geometry for optimum flow. Ideally, there should be no dead zones. SOLUTIONS FOR MEASURING DEAD ZONES ■ Measurement of pressure with an inline...

Instruments and equipment components are adapted to the process using proven connection technology and gaskets. A gasket has to function properly throughout its entire service life under all process and cleaning conditions and can either be designed as O-ring or gasket. CORROSION-FREE STAINLESS STEEL Stainless steel provides excellent corrosion protection under the process conditions of applications in the food, pharmaceuticals and biotechnology industries. The selection of the appropriate stainless steel for the specific application depends largely on the corrosiveness of the process and...

The integration of measuring equipment into production plants is a sensitive undertaking. Any interference in the line can cause risks particularly in the hygienic production of food or medicines. What needs to be taken into consideration? GAP-LESS INSTALLATION It is crucial that the measuring instrument itself is centred by a cylindrical guide, avoiding edges and projections and producing a gap-free seal towards the inside of the pipe. CONNECTION OPTIONS LABOM measuring instruments are available with a range of different connections and can be integrated into the most diverse production...

CONNECTION TECHNOLOGIES FOR TEM Temperature is one of the most commonly measured values in pharmaceutical manufacturing, to monitor and control the production process and also sterilisation procdures with saturated steam (SIP). INVASIVE TEMPERATURE MEASUREMENT PREFERABLY ELECTRIC PRECISELY WITH THERMOWELL INVASIVE CONNECTIONS Electrical measuring equipment is used almost exclusively to process measuring results and comply with documentation requirements. The conventional immersion probe has been evolved to permit hygienic, invasive measurement using an orbitally welded thermowell system –...

PERATURE MEASUREMENT NON-INVASIVE TEMPERATURE MEASUREMENT ON THE SURFACE OF THE PIPE NON-INVASIVE CONNECTIONS A sensor tip reaching into the process represents a significant obstruction to the flow with very small pipe diameters. Inline sensor: Measuring the surface of the pipe can be the solution specifically with respect to pharmaceutical measuring tasks: Non-invasive and without the associated hygiene risks. Alternatively, an inline sensor can be integrated in the pipe. ◾◾ Food pipe threaded connection DIN 11851 ◾◾ Threaded connection IDF ISO 2853 ◾◾ Clamp connection, ISO 2852-compliant...
