Page 6: Introduction
INDUSTRIAL MONITORING INSTRUMENTATION DIVISION Introduction The Model 640/641/645/646 Series Industrial 4-20 mA Sensors combine the capabilities of a piezoelectric vibration sensor and a 4-20 mA vibration transmitter into a ruggedized housing. The sensors output a 4-20 mA signal that is proportional to the overall velocity or acceleration of the machinery. Ideal for monitoring the vibration of process equipment such as fans, motors and pumps, the output of the sensor is used for process control or predictive maintenance. -
Page 7: Taking Measurements
INDUSTRIAL MONITORING INSTRUMENTATION DIVISION Taking Measurements When reading the current output from the unit, use the following formula to calculate the vibration level: Measured mA 640AX0 640AX1 640AX2 4.00 0.0 ips, pk 0.0 ips, pk 0.0 ips, pk 8.00 0.125 ips, pk 0.25 ips, pk 0.5 ips, pk 12.0... -

INDUSTRIAL MONITORING INSTRUMENTATION DIVISION RV Option continued . . . For integral cable sensors: 4-20 mA Positive BLACK 4-20 mA Negative (same as green) GREEN Acceleration Negative (same as black) WHITE Acceleration Positive Note: The acceleration signal Negative has to be isolated from any grounding. If this is grounded, the 4-20 mA loop will short, causing no output. -
Page 9: Installation
INDUSTRIAL MONITORING INSTRUMENTATION DIVISION Installation When choosing a mounting method, consider closely the advantages and disadvantages of each technique. Typical mounting types are stud, direct adhesive, adhesive mounting base and magnetic mounting base. Since the frequency response is limited to 1 kHz on the 640/641, any of the four methods can be used without seriously affecting the data values. - Page 10 INDUSTRIAL MONITORING INSTRUMENTATION DIVISION Standard Stud Mount Procedure continued . . . STEP 1 First, prepare a smooth, flat mounting surface, and then drill and tap a mounting hole in the center of this area as shown in Figure 3. A precision-machined mounting surface with a minimum finish of 63 µin [0,00016 mm] is recommended.

Page 11: Adhesive Stud Mount Procedure
INDUSTRIAL MONITORING INSTRUMENTATION DIVISION Adhesive Stud Mount Procedure Adhesive mounting is often used for temporary installation or when the machine surface cannot be adequately prepared for stud mounting. Adhesives like hot glue or wax work well for temporary mounts; two-part epoxies and quick-bonding gels provide a more permanent mount. -
Page 12: Direct Adhesive Mount Procedure
INDUSTRIAL MONITORING INSTRUMENTATION DIVISION Direct Adhesive Mount Procedure For restrictions of space or for convenience, most sensors (with the exception of integral stud models) can be adhesive-mounted directly to the machine surface. STEP 1 Prepare a smooth, flat mounting surface. A minimum surface finish of 63 µin [0,00016 mm] generally works best. - Page 13 INDUSTRIAL MONITORING INSTRUMENTATION DIVISION Magnetic Mount Procedure continued . . . figure 8 – magnet types Sensor Stud M ounts to Top Surface of M a gnet Dual-R ail M agnet Flat M agnet M ounting Pad w ith M agnet ALL SUR FA CES S HOULD BE FLAT AN D SM O O TH STEP 1 After choosing the correct magnet type, inspect the unit, verifying that the mounting surfaces are flat and smooth.
