Descrição

Starting from Apr 1st 2018, DP2000/9000 Series have been discontinued. As a possible substitute, please check out the DPPT Panel Meter or DP20 Series for details.

The DP2000-H and DP9000-H are frequency meter/ tachometers with extensive zero and scale factor adjustment capability for direct readout in engineering units for RPM, flow and speed. Input frequencies can be as low as 100 Hz or as high as 20 kHz for the display maximum, which is 1999 for the DP2000-H and 9999 for the DP9000-H. Zero offset is available for use with transducers with a frequency output and a live zero. Choose any combination of display type (LED or LCD), operating power, input type and range, analog output, and digital or control outputs.

Easy to Interface
The meters are designed for easy interfacing to transducers with a frequency or pulse output. These include turbine flowmeters, passive magnetic pickups, and active proximity detectors with NPN, PNP or NAMUR (1 mA/3 mA) output. To accommodate different signal levels and provide noise immunity, the DC trigger level can be adjusted from -1 to 5V, and two hysteresis levels are selectable. Signals as low as 15 mV p-p or as high as 130 V rms can be monitored directly.

Configuration and Calibration
The units can be configured and scaled in the field. Adjustments for zero, span, and trigger level are accessible from the front panel to allow final calibration or recalibration without removal of the meter from the panel. The meters can be scaled to read RPM directly. With the dual-setpoint controller (optional), they can provide under and overspeed alarms. The 1 mV/ count analog output (standard) can be used to drive a strip-chart recorder for permanent. user-selected display span.
