Digital Proximity System
Operation and Maintenance Manual
100576 • REV C
The DPS (Digital Proximity System) devices
consists of two modules: the MX2033 and
MX2034. The MX2033 is a conventional
3-wire driver while the MX2034 is a two-
wire current loop transmitter. Users can con-
figure either unit to measure peak-to-peak
vibration, gap distance, or rotational speed.
These products are used in conjunction with
a proximity probe and extension cable to
measure the vibration levels, gap distances,
or rotational speed of machinery shafts. Us-
ers can configure the units via a USB cable
and configuration software.

    You can easily custom calibrate the DPS for your probe following the procedure in this sec- tion. Perform the Scale Factor Verification as described in section 4.1. NOTE: The custom calibration process overwrites any previous custom calibration. Standard Metrix factory calibrations for MX2030 and 7200 5m and 9m systems are not affected.

    NOTE: Metrix does not recommend using the custom calibration feature to calibrate mismatched systems. Mis- matched systems degrade probe and cable temperature performance.
