Metrix MX2033 User manual

Digital Proximity System
Operaon and Maintenance Manual
100576 • REV C
The DPS (Digital Proximity System) devices
consists of two modules: the MX2033 and
MX2034. The MX2033 is a convenonal
3-wire driver while the MX2034 is a two-
wire current loop transmier. Users can con-
gure either unit to measure peak-to-peak
vibraon, gap distance, or rotaonal speed.
These products are used in conjuncon with
a proximity probe and extension cable to
measure the vibraon levels, gap distances,
or rotaonal speed of machinery shas. Us-
ers can congure the units via a USB cable
and conguraon soware.

1.3 RECEIVING, INSPECTING AND HANDLING THE SYSTEM
Metrix ships the probe, extension cable, and driver as separate units that the user intercon-
nects at the installaon site. Carefully remove all equipment from the shipping containers
and inspect it for shipping damage. If you see shipping damage, le a claim with the carrier
and submit a copy to Metrix Instrument Co. Include part numbers and serial numbers on all
correspondence. If no damage is apparent and the equipment is not going to be used imme-
diately, return the equipment to the shipping containers and reseal unl ready for use. Store
the equipment in an environment that is free from potenally damaging condions such as
extreme temperature, excessive humidity, or a corrosive atmosphere.
2. OVERVIEW
The Metrix Digital Proximity System module comes in two versions:
• MX2033 – 3-wire proximity driver
• MX2034 – 2-wire, loop powered proximity transmier
A complete DPS system requires a DPS module, a proximity probe, and an extension cable.
You can congure the MX2033 and MX2034 modules to operate with the probe and cable
combinaons shown in Table 1.

The MX2033 signal output is proporonal to the distance between the probe p and the
target material. The signal output follows API Standard 670 and is compable with most
connuous vibraon monitoring systems. The MX2033 uses -24Vdc excitaon and provides
an output scale factor of 7.87 mV/mm (200mV/mil) for 5 mm and 8mm probes.

The MX2034 provides an ISA standard 4-20 mA signal proporonal to vibraon, axial posi-
on sha speed (RPM) for direct connecon to a PLC, DCS, SCADA system, or other instru-
mentaon without requiring a separate monitor system. The MX2034 is powered by +24
Vdc, supplied within the current loop. The MX2034 is user congurable to funcon as either
a radial vibraon transmier (where the 4-20 mA signal is proporonal to peak-peak vibra-
on amplitude), as an axial posion transmier (where the 4-20 mA signal is proporonal to
average probe gap) or as a speed (RPM) transmier (where the 4-20 mA signal is propor-
onal to the speed of a machine). For convenience when connecng to signal analyzers,
portable data collectors, and test instrumentaon, the raw vibraon signal is available at
a short-circuit protected BNC connector. Refer to secon 3.6 of this manual for important
informaon and cauons regarding proper use of this connector.

type specied at the me of ordering.
3.5.4.2 PROBE DIAMETER
The DPS supports 5mm, 8mm and 11mm probe p diameters as part of its standard factory-
loaded curve set.
3.5.4.3 TARGET MATERIAL
DPS units support the standard four probe series listed in secon 3.5.4.1 calibrated for 4140
steel. The addional probe type specied at the me of ordering may be calibrated to a
variety of materials. Contact Metrix for informaon on special material calibraons.
3.5.4.4 MEASUREMENT
The Measurement eld is only acve for the MX2034 transmier model. The MX2034 sup-
ports three measurements: Radial Vibraon, Axial Posion, and Sha Speed (RPM).
3.5.4.4.1 RADIAL VIBRATION
The MX2034 performs a peak to peak detecon and drives the 4-20 mA output proporonal
to the congured range.
1) Select the new conguraon
parameters from the drop down list
2) Click the  buon to send the new

3.5.4.5 RANGE
The Range choices are dierent for Radial Vibraon, Axial Posion, and Sha Speed (RPM)
measurements.
3.5.4.6 mA DIRECTION
The MX2034 allows conguraon of upscale or downscale for the 4-20mA output of axial
posion measurements only. Upscale means that for the range selected in 3.5.4.5, 4mA
corresponds to boom of scale and 20mA corresponds to top of scale; downscale reverses
these convenons and means that 20mA corresponds to boom of scale and 4mA corre-
sponds to top of scale.
3.5.5 CONFIRMING THE CONFIGURATION
Aer clicking the Send buon, you will have the opon to abort the conguraon change.
Press the Yes buon to connue.
3.5.6 PRINTING A LABEL
Aer sending a conguraon change, the soware will give you the opon to print a label.

Prinng Kit which contains instrucons, Avery Labels, and
overlays needed for prinng up to 16 labels.

3.5.7 INSTALLING THE LABEL
Remove the backing from the polycarbonate label and adhere the printed label inside the
clear window. Aach both labels to the side of the DPS unit. Refer to DPS Label Kit manual
100528 for addional details.
3.6 USING THE MX2034 BUFFERED OUTPUT
Due to the two wire, loop-powered MX2034 transmier design, the current loop common
oats on top of the voltage developed across the current loop sense resistor.

Doc# 100576 • REV C (Sept 2017) Page 19 of 42
The buered output common is protected against ground loop currents aecng the current
loop output with a 10kΩ resistance between the buered output common and the loop
common.
Metrix recommends using a ground isolated instrument or signal isolator. The meter, oscil-
loscope or analyzer used to measure the gap voltage or to observe the vibraon signal
(DYNAMIC OUTPUT) must have an input impedance of one megohm or greater.
The scale factor of the output signal is 200 mV/ mil.
Metrix recommends a maximum cable length of 15  (5 m) when connecng to the buered
output due to noise suscepbility caused by the high input and output impedances.
4. VERIFICATION AND CALIBRATION
This secon describes the steps to verify proper DPS operaon and to custom calibrate your
DPS to your specic probe and cable.
 When using the MX2034 BNC connector, exer-
cise special care to prevent ground loops that could alter
the 4-20mA output, resulng in spurious alarms or ma-
chine trips. Such ground loops can occur when connecng
to grounded test equipment or mulple input test equip-
ment. Metrix recommends use only with ungrounded test
equipment, such as baery-powered portable meters,
or grounded test equipment with dierenal inputs (i.e.,
neither side of input connecon is ed to ground). Also,
cable lengths between the BNC connector and test equip-
ment should be kept suitably short (5m or less) to prevent
unwanted noise.
The DPS requires the probe and extension cables be
from the congured probe series, combine to the cong-
ured system length, and view the congured target mate-
rial in order to meet system range and accuracy

4.1 SCALE FACTOR VERIFICATION
Follow these steps in this secon to verify the voltage output scale factor. The basic proce-
dure is:
Obtain the correct target material
Assemble the test instruments and equipment
Electrically zero the probe
Measure the output voltage in xed gap increments
4.1.1.1 OBTAINING THE TARGET
Use a 1.2 inch or larger target with 5 mm or 8 mm probes. Be sure your target material
matches the material the DPS calibraon material. To verify the calibraon material, follow
the steps listed in Figure 16.
