* FEATURES AND APPLICATIONS
The Model 54e C Analyzer/Controller, with the appropriate sensor, monitors and controls conductivity/ resistivity in a variety of industrial processes. The analyzer can use either a contacting electrode or an inductive (toroidal) conductivity sensor, selected via keyboard entry. Process measurement selections are conductivity, resistivity, raw conductivity, or percent (%) concentration.
The Model 54e C is a member of the Rosemount HART family of instruments, which is designed to communicate with any host device that accepts the Hart communication protocol.
The temperature correction algorithm is user-selectable. Choose from high purity water (dilute sodium chloride), cation conductivity (dilute hydrochloric acid), or an adjustable linear temperature coefficient (0 to 5.00%/ C). The high purity water and cation conductivity corrections are good to 100 C. The linear temperature correction applies between -5 to 200 C. The user can set the linear temperature coefficient's reference temperature.
The percent concentration measurement includes the choice of four common solutions (0-12% NaOH, 0-15% HCl, and 0-25% or 96-100% H2SO4) which include specific nonlinear temperature corrections that depend on the concentration being measured and the process temperature. A versatile data entry menu for entry of a custom solution with concentration and conductivity values for up to five points lets the analyzer generate a best fit quadratic curve. Reference temperature and temperature slope may be adjusted to provide optimum results.
The two independent, isolated outputs provide 4-20 or 0-20 mA signals for the process measurement and temperature. The controller option also allows PID control choices acting on process measurement or temperature. Manual control of the output may also be selected for routine maintenance and tests.
The Model 54e C has three fully programmable alarm relays. Alarms can be configured as high or low logic acting on the process measurement or temperature. Any of these relays can also be set up to act as an interval timer. The control option allows the additional choice of Time Proportional Control. During any relay activation, a corresponding Green LED is illuminated.
In the event of a fault condition, the analyzer will display a descriptive diagnostic message, illuminate a red LED on the front panel, and energize the dedicated fault relay. All operations and descriptive messages can be field selected to display in English, French, German, Italian, or Spanish.
