Dairy/Food Application

A major cheese processor is measuring the volume before and after a separator (similar to a centrifuge) using mass flow-meters with HART. Each flowmeter is capable of gathering several different variables including flow rate, density, temperature and totalized volume. These measurements can then be used to calculate the efficiency of the separator.

Without the Spectrum Controls Analog I/O Module with HART Protocol, the manufacturer would have had only a few options available to gather this data. Each was costly and complicated. 

Options considered were: using a remote I/O solution, which is complicated and cumbersome; a non Allen-Bradley solution which would require a third party PLC or PC data retrieval system; or finally placing extra analog sensors into the system to gather the variables. The Spectrum Controls Analog I/O HART Module offered a simple, cost-effective and flexible solution.
