"Electronic transmitter \/ controller for the measurement of the specific resistivity or specific conductivity in high purity water.","Features"

特性

• Measuring and control transmitter in a rugged aluminum enclosure (IP 66).
• Measurement ranges: - Resistivity: 0.001 to 200 MΩ-cm - Conductivity: 0.005 to 1000 μS/cm
• Sensor connections for a two-electrode sensor with built-in NTC temperature probe like Swansensor RC-U or RC-UT and for a digital sample flow meter.
• Big backlit LC display for the reading of measuring value, sample temperature, sample flow, temperature compensation type and operating status.
• Easy user menus in English, German, French and Spanish. Simple programming of all parameters by keypad.
• Wide range of selectable temperature compensations for different sample conditions.
• Electronic record of major process events and calibration data.
• Real-time clock for time stamp in data logs and for automated functions.
• Data logger for 1’500 data records stored at a selectable interval. (Data download to PC requires optional HyperTerminal interface).
• Galvanically separated sensor connection.
• Overvoltage protection for in- and outputs.
• Two current outputs (0/4 - 20 mA) for measured signals.
• Potential-free alarm contact as summary alarm indication for programmable alarm values and for instrument faults.
• Two potential-free contacts programmable as limit switch or PID-control.
• Input for potential-free contact to freeze the measuring value or to interrupt control in automated installations (hold function or remote-off).
