LABOM Live Contact Pressure Gauge - BE4300

German LABOM live contact pressure gaugeDetailed Introduction

LABOM Live Contact Pressure Gauge - BE4300

The production of products that have a direct or indirect impact on public health should be based on domestic regulations, depending on the different trading regions. The code of conduct includes the execution and organizational rules of methods, production, production environment, and inspection.
The clean design of production plants and pressure gauges is a basic requirement for producing error free products. The structure and installation of the pressure gauge must ensure that there are no groups prone to pollution during operation; And clean without any blemishes.

Classification of German LABOM Live Contact Pressure Gauge Equipment and Components

EHEDG (European Cleanroom Design Group) categorizes factories into three types based on their cleanliness.
Class I: Dust stoves and microorganisms can be removed on-site without dismantling the factory (CIP process)
Class II: Cleaning the environment by dismantling the factory building
Class III: Cleanliness of factory buildings with reduced microorganisms (closed process)

Requirements for Measuring Equipment of German LABOM Live Contact Pressure Gauge

In addition to the requirements for measuring micro aspects, the design of clean pressure gauges also needs to consider
·Some other conditions, such as:
·Production process
·Surface composition of wetted parts
·Connectivity
·Instrument Design
·Endurance/Material Compatibility
·Special process operating conditions

Surface composition of wetted parts of German LABOM live contact pressure gauge

The surface composition of the wetted parts is crucial for the efficiency of the CIP process. Scratches, dead spots, fine needle holes, cavities, and cracks should be avoided to resist contamination from unexpected substances such as product residues, microorganisms, and cleaning and disinfection residues.
Generally speaking, a smooth surface with an average roughness value Ra ≤ 0.8 μ m and an average roughness value Ra ≤ 1.6 μ m near welding can achieve good surface cleanliness. If Ra=μ m, no improvement in cleanliness can be expected.
LABOM can provide standard instruments for clean design with the following surface qualities for medium contact:
Rotating component Ra ≤ 0.8 μ m
Thin film Ra ≤ 0.4 μ m
Laser welding:
Thin/leaf shaped sheet Ra ≤ 0.8 μ m
Electropolishing can improve surface quality. When polishing chromium nickel copper to release oxygen, it assimilates the passivation layer on the surface of the material, demonstrating significantly improved corrosion resistance, which is related to different surface treatments. If necessary, other treatment methods and methods to reduce surface roughness can also be provided.LABOM Live Contact Pressure Gauge - BE4300

Connectivity

The pipe connection system that complies with DIN11851 is not suitable for CIP processes. According to EHEDG, they belong to Type II equipment.
A sterile consortium with the following characteristics has been developed for compatible factory CIP:
·Centralized with cylindrical guide
·Metal blockage under tension
·Defined pre pressurized sealing system
·There is no clear seal inside the tube
The pipe system with circular threads and flange joints according to DIN11864 can meet these requirements. Traditional connection systems with other threads or inclusions can also be provided.
LABOM pressure and temperature measuring instruments are equipped with integrated connectors, following
·Compliant with DIN11864-1 Sterile Tube Consortium
·Compliant with DIN11864-2 sterile flange joint
·Manufacturer rules such as S ü dmo. Neumo. Guth. Tuchenhausen, and others

Sealing material

Due to the fact that sealing components are largely dependent on process parameters, they are not part of standard transportation procedures.
Sealing must be technically appropriate and demonstrate many characteristics:
·Good disinfection performance
·Smooth surface for efficient removal of accessory particles
·*Non toxic materials
·Colorless and odorless
·Regarding the necessary cleaning and disinfection agents for the product, as well as the endurance of the CIP cycle.
When selecting a sealing system, it is necessary to comply with the application regulations and certifications of appropriate certification bodies (LMBG, FDA, US30A - Cleanliness Standards, etc.)

Pressure Measurement Technology of German LABOM Live Contact Pressure Gauge

Pressure gauges with integrated or attached bellows are used for clean measurement
The arrangement is very ideal. Correctly selecting components can solve a large number of tests
Quantity issue:
Measurement points arranged without dead zones under very clean conditions
■ Instrument protection can resist corrosion, high viscosity or crystalline measuring media
■ Resist high temperature and temperature fluctuations of the measuring medium
■ Instrument protection can resist vibrations caused by capillary tubes that are joined together
■ Independent membrane and surface coating for special applications using special materials

Most manufacturers provide pressure gauges that are suitable for use with LABOM bellows. The specially designed LABOM pressure gauge reduces the dead zone volume and is very suitable for working at high process and cleaning temperatures.

Connection System of German LABOM Live Contact Pressure Gauge

The connection system is used to connect pressure gauges and bellows. LABOM can provide various versions with process temperatures up to 260 ℃.
