Page 8: Introduction
Introduction The Model 640/641/645/646 B Series Industrial 4-20mA Sensors combine the capabilities of a piezoelectric vibration sensor and a 4-20mA vibration transmitter. The sensor outputs a 4-20mA 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 10: Operation And Wiring
Operation and Wiring Standard Wiring The Model 640/641/645/646 B Series operates from a standard 2-Wire, 4-20mA loop. If using a loop powered unit, attach the positive (+) input from the power supply to Pin A or Red wire on the sensor and the negative (-) input from the power supply to Pin B or Blue Wire of the sensor. -
Page 11: Taking Measurements
Taking Measurements When measuring the current output from the unit, use the following formula to calculate the vibration level: Vibration Output = (Measured Output – 4mA) x (Full Scale Vibration Output /16mA) Measured mA 640BX0 640BX1 640BX2 4.00 0.0 ips, pk 0.0 ips, pk 0.0 ips, pk 8.00... -
Page 12: Rv Option
RV Option The RV (raw vibration) option includes a 100mV/g ±20% additional output. The accelerometer frequency range is 1 Hz-1 kHz, maximum amplitude of 15 g-pk. Data collectors or analyzers can use this vibration signal for further analysis. This output is extended to the RVVO (Raw Vibration Velocity Output) option, which integrates the signal to a value of 100 mV/IPS (±20%). -
Page 13: To Option
TO Option The TO (Temperature Output) option includes an additional independent 4-20mA output for temperature measurement. The temperature range is from -40°C to 125°C with an overall accuracy of ±5%FSO. The imbedded temperature sensor monitors the environment internal to the sensor housing and is situated at approximately mid level. -
Page 14: Installation
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 15: Standard Stud Mount
Standard Stud Mount Procedure This mounting technique requires smooth, flat contact surfaces for proper operation and is recommended for permanent and/or secure installations. Stud mounting is also recommended when testing at high frequencies. Note: DO NOT attempt mounting on curved, rough or uneven sufaces, as the potential for misalignmen and limited contact surface may significantly reduce the senor’s upeer operating frequnecy range. -
Page 16: Adhesive Stud Mount
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. Note: Adhesively mounted sensors often exhibit a reduction in high-frequency range. -
Page 17: Magnetic Mount
Magnetic Mount Procedure Magnetic mounting provides a convenient means for making portable measurements and is commonly used for machinery monitoring and other portable or tending applications. Note: The correct magnet choice and an adequately prepared mounting surface is critical for obtaining reliable measurements, especially at high frequencies. -
