Bürkert | Mass Flow Controller Introduction The term “gas” has its origin in the Greek word for chaos. Coincidence? Probably not! Gases are peculiar. They are volatile, sometimes reactive, and always expansive. This means that gases have very special handling requirements. Process gases are indispensable in industrial manufacturing. From coating and hardening surfaces, right through to the fermentation processes used in the pharmaceutical world. Inert gases are used for example to protect packaged foodstuffs against the effect of atmospheric oxygen and in metal processing to prevent the...

Bürkert | Measuring Principle The Measuring Principle of Thermal Mass Flow Mass Flow Controllers − Setup and Functioning The physical law is well known – heat always flows towards lower temperatures. So if a body has All Mass Flow Controllers from Bürkert are compact devices that control the mass flow of gases. a higher temperature than its environment, it will give off its heat energy to the neighbouring mass. They control a preset flow rate reference value – regardless of disturbance variables such as pres- So our thermal/calorimetric measurement technique utilises this principle, i. e....

Bürkert | Setup and Functioning Inline Sensor MEMS Sensor The Inline sensor works in the CTA operating mode (Constant Temperature Anemometer), whereby In contrast to the Inline sensor, with which the mass flow in the main channel is measured, the an electrical heating resistance (RS) and a measurement resistance (RT) are regulated at a constant MEMS sensor determines the values directly in a secondary channel. In detail: A laminar flow temperature difference. Both resistances are directly placed in the flow channel; three more resist- element brought into the main channel ensures the...

Bürkert | Setup and Functioning Capillary Sensor Solenoid Control Valve Types 8710/8700, 8715/8705 As with the MEMS sensor, a laminar flow element also causes a pressure drop in the main channel Solenoid control valves are electromagnetic control valves. They open to specific stroke positions – with the capillary sensor. A part of the total flow rate flows through a parallel running secondary depending on the control signal. Two forces counter one another in the valve: one a spring, and the channel. The decisive differences: the capillary sensor has no direct contact with the medium. The...

Industrial Communication – with Fieldbus and Ethernet With the introduction of fieldbuses in the 1980s, information technology came into play at the field level of automation. Manufacturer-driven, fieldbus systems arrived on the market one after another. Well known and wide spread representatives are PROFIBUS, CANopen and DeviceNet. Basic advantages to conventional, hardwired architectures include reduced wiring costs (hardware) and easy integration of single components into an industrial plant (software). These are key factors in process automation. Strong competition for fieldbus systems...

EDIP (Efficient Device Integration Platform) User interface of the Bürkert Communicator. The graphical programming interface User-f(x) is integrated into this software. The User-f(x) allows to program customized system control functions – e.g. for gas blending. The term EDIP stands for Efficient Device Integration Platform. It is the new Bürkert device platform which standardizes the operation, communication and interfaces of many process instruments (e.g. sensors, mass flow controllers). With EDIP all büS devices from Bürkert can be integrated into the proprietary büS system and can be...
