You have one or more mass flow controllers and need to power them and provide a setpoint signal. How can you do that?
Bronkhorst offers the Digital Single Channel Control Module for use with Thermal Mass Flow Controllers, Pressure Controllers and other transmitters and transducers or, as in master/ slave control systems, in combination with these.
The Bronkhorst High-Tech E-7000 Series is designed to easily enable the user to program and power one Mass Flow Meter/Controller, Pressure Transducer/Controller or other device. The micro-processor based unit offers great flexibility in indication of tags, fluid names and counter units in combination with measuring and setpoint values, both in percentages or actual units. Furthermore polynomial functions of maximum 8 calibration curves, offering an accuracy of +/- 0.5% off reading plus +/- 0.1% off full scale, can be stored.
Based on the modular technique of the single channel modules, it is easy to assemble multi channel configurations. This way 3 channels fit into a half 19" housing and 6 channels fit into a 19" housing, either for rack mount or table top.
For application requiring host control by PC, Bronkhorst offers a module including a RS-232/FLOW-BUS interface or a Profibus-DP/FLOW-BUS interface.
Dissolution testing is the test performed on pills and tablets, medical devices, etc to determine the rate at which the coating dissolves.
