The IND131/ IND331 series of industrial process weighing terminals and transmitters is claimed to deliver equipment that offers comprehensive application features, speed and connectivity. A high A/ D update rate of 366 Hz is combined with Trax DSP noise filtering to ensure users get updated weight information as needed for automatic processes. Trax DSP is a combination of multi-stage filters that filter out background noise and vibration, making the IND131/ IND331 terminal suitable for mixing, agitating and any other dynamic process. The versatile terminal can easily connect to multiple automation platforms. It provides direct PLC and DCS connectivity using 4-20 m A, digital I/ O, RS232/485, Allen- Bradley RIO, Profibus DP, Device Net, Ether Net/ IP and Modbus TCP. The process terminals offer four different methods for the calibration of weighing systems: traditional calibration method with independent zero and span calibration; step calibration method using a combination of certified weights and substitute mass; Cal Free method for calibrating without test weights; and Calibration from PLC method. The Cal Free calibration method offers an alternative to traditional methods. This is particularly useful for large tanks or silos where the use of test weights to calibrate the scale is not practical The Calibration from PLC method allows the PLC programmer to automate the calibration process. This alleviates the need for an operator to interact with the terminal during calibration thus reducing the potential of operator error. Available in multiple enclosure styles to match any process environment, the series includes IND131 DIN rail mount, IND131 junction box, IND331 panel mount and IND331 harsh, desk or wall mount. The complete configuration is saved on an internal SD memory card. This ensures fast restoration or duplication of user settings and configuration on replacement.
Machine and instrument manufacturers supplying the Chemical, Food and Pharmaceutical industries need tailored weighing components. The IND131/331 weighing.
