5 The sec ons below provide more module informa on. 2.1 MX2033 THREE WIRE PROXIMITY DRIVER 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. 2.2 MX2034 TWO WIRE TRANSMITTER The MX2034 provides an ISA standard 4-20 ma signal propor onal to vibra on or axial posi- on for direct connec on to a PLC, DCS, SCADA system, or other instrumenta on without requiring a separate monitor system. The MX2034 is powered by +24 Vdc, supplied within the current loop. The MX2034 is user-programmable 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), or as an axial posi on transmi er (where the 4-20 ma signal is propor onal to average probe gap). 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. 2.3 FOR MORE INFORMATION Refer to these documents for more informa on: MX2030 Digital Proximity Transducer System Datasheet DPS Hazardous Area Installa on Manual DPS Label Kit Manual Doc# REV B (April 2015) Page 5 of 42

A ach both labels to the side of the DPS unit. Refer to DPS Label Kit manual 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 floats on top of the voltage developed across the current loop sense resistor. Doc# REV B (April 2015) Page 18 of 42

19 The buffered output common is protected against ground loop currents affec ng the current loop output with a 10kΩ resistance between the buffered output common and the loop common. Metrix recommends using a ground isolated instrument or signal isolator. The meter, oscilloscope 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 buffered output due to noise suscep bility caused by the high input and output impedances. CAUTION: When using the MX2034 BNC connector, exercise special care to prevent ground loops that could alter the 4-20mA output, resul ng in spurious alarms or machine trips. Such ground loops can occur when connec ng to grounded test equipment or mul ple input test equipment. Metrix recommends use only with ungrounded test equipment, such as ba ery-powered portable meters, or grounded test equipment with differen al inputs (i.e., neither side of input connec on is ed to ground). Also, cable lengths between the BNC connector and test equipment should be kept suitably short (5m or less) to prevent unwanted noise. 4. VERIFICATION AND CALIBRATION This sec on describes the steps to verify proper DPS opera on and to custom calibrate your DPS to your specific probe and cable. NOTE: The DPS requires the probe and extension cables be from the configured probe series, combine to the configured system length, and view the configured target material in order to meet system range and accuracy Doc# REV B (April 2015) Page 19 of 42

20 CAUTION: Do not connect test equipment or cables to the driver unless the area has been determined to be non-hazardous 4.1 SCALE FACTOR VERIFICATION Follow these steps in this sec on to verify the voltage output scale factor. The basic procedure is: Obtain the correct target material Assemble the test instruments and equipment Electrically zero the probe Measure the output voltage in fixed gap increments 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. 1) Retrieve the DPS configura on 2) Verify the Target Material configura on Figure 16: Verifying the Target Material Configura on Doc# REV B (April 2015) Page 20 of 42

21 ASSEMBLE THE TEST INSTRUMENTS AND EQUIPMENT Verifica on requires these instruments and equipment Spindle micrometer Digital Mul meter Power Supply (-24 Vdc +/- 1Vdc) 10 kohm resistor NOTE: Use the BNC connector on the MX2034 to verify the scale factor. The terminal strip signal pin is not used on the MX2034. Figure 17: MX2033 Scale Factor Valida on Set Up Doc# REV B (April 2015) Page 21 of 42

23 MEASURE THE VOLTAGE IN GAP INCREMENTS Increase the micrometer 10 mil (0.25 mm) increments and fill in the measured SIG Voltage in the table below. Table 4: Verifica on Data Table mils mm SIG Voltage To calculate the Average Scale Factor (ASF), subtract the voltage measured at 10 mils (0.25 mm) from the voltage at 90 mils (2.25 mm)and divide by the full scale range of 80 mils (2 mm) Example: Voltage at 90 mils (2.25 mm) is V Voltage at 10 mils (0.25 mm) is V ASF = (-0.98) - (-17.1)/80 = mv/mil Or ASF = (-0.98) - (-17.1)/2 = 8.06 mv/mm To calculate the Incremental Scale Factor (ISF) at each gap, subtract the SIG voltage measured 10 mils (0.25 mm) below each increment and divide by 10 mils (0.25 mm). Example: Voltage at 40 mils (1.0 mm) is -7.1 V Voltage at 50 mils (1.25 mm) is V ISF = (-9.02) - (-7.1)/10 = -192 mv/mil Or ISF = (-9.02) - (-7.1)/0.25 = mv/mm Doc# REV B (April 2015) Page 23 of 42

24 4.2 SCALE FACTOR CUSTOM CALIBRATION You can easily custom calibrate the DPS for your probe following the procedure in this sec- on. Perform the Scale Factor Verifica on as described in sec on 4.1. NOTE: The custom calibra on process overwrites any previous custom calibra on. Standard Metrix factory calibra ons for MX2030 and m and 9m systems are not affected. Open the DPS so ware and click the bu on. The custom calibra on window opens. Enter the voltages measured at each gap from the Scale Factor Verifica on data. NOTE: Voltages are assumed nega ve. Do not put a - sign in front of each voltage. When complete, click the Generate and Load Lineariza on bu on. The so ware will adjust the DPS lineariza on to match the probe and cable. Doc# REV B (April 2015) Page 24 of 42

25 Fill in the voltages measured at each gap and then click the Generate and Load Lineariza on bu on. Figure 20: Filling in the Custom Calibra on Voltages At comple on, the following dialog box shows. Click OK to finish. Figure 21: Custom Calibra on Successful Comple on If the probe and cable run very far out of specifica on, the DPS may not be able to linearize the curve. In this case, the so ware will show an error message as shown in Figure 22. Doc# REV B (April 2015) Page 25 of 42

26 Figure 22: Custom Calibra on Shortened Curve If this occurs, verify that the voltages you entered were correct. Verify that your system components combine to the correct length. If all is correct, you can choose to accept the shortened curve or hit cancel and use a different probe and cable. In some cases, probes and cables that are far out of specifica on can be brought into specifica on by itera ng the custom calibra on process several mes. NOTE: Metrix does not recommend using the custom calibra on feature to calibrate mismatched systems. Mismatched systems degrade probe and cable temperature performance CURRENT LOOP VERIFICATION MX2034 ONLY Follow the steps in this sec on to verify the current loop output for Posi on or Radial Vibra- on configured DPS units POSITION CONFIGURED UNITS The transmi er current output is linearly propor onal to the average probe gap (posi on) between 4 ma and 20 ma. Use the instruments and equipment shown in Figure 23 to verify a posi on transmi er current output. Doc# REV B (April 2015) Page 26 of 42
