Page 8: Introduction
Introduction The Model 640/641/645/646 B7 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 B7 Series uses plug-in type screw terminal connectors for all input and output connections and operate from a standard 2-wire, 4-20mA loop. Attach the positive (+) input from the power supply to Pin 2 and the negative (-) input from the power supply to Pin 3. Figure 1 –... -
Page 11: Taking Measurements
- Resistor value must be less than: (Vsupply – 12) x 50. 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... -
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. Figure 3 – RV wiring Note: -The Acceleration Signal Negative has to be isolated from any grounding. -
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: Ep Option
EP Option The EP option includes an Explosion Proof capped elbow for applications in rigid or IMC conduit systems where space is limited and access is needed for pulling conductors or maintenance. Standard conduit hub size is 1”NPT. CAPPED ELBOW 3.850 5.777 3.990... -
