Permanently record pressure, flow, level, temperature, or other process variables with the Model CR20 Universal Input Recorder: The microprocessor-based unit accepts input from two-wire transmitters or sensors with a 1 - 20 mA, 4 - 20 mA, 0 - 5 VDC, or 1 - 5 VDC output. Monitor and record remote process signals on the 8" (20 cm) diameter chart paper: Units feature user selectable output ranges and recording times, and high/low alarms.View current measurements on the large LCD or recall minimum and maximum values.
Model CR20 Circular Chart Recorder includes CR776 chart paper (0 to 100 range, 7 day, 100 sheets), one pen, AC adapter, and instruction manual.
