Page 6: Introduction
Introduction The Model 642/643/647/648 A 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 8: Operation And Wiring
Operation and Wiring Standard Wiring The Model 642/643/647/648 A 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 9: 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 642AX0 642AX1 642AX2 4.00 0.0 ips, pk 0.0 ips, pk 0.0 ips, pk 8.00... -
Page 10: Rv Option
RV Option The RV (raw vibration) option includes a 100mV/g ±20% additional output. The accelerometer frequency range is 1 Hz-10 kHz, maximum amplitude of 15 g-pk. Data collectors or analyzers can use this vibration signal for further analysis. Figure 3 – RV wiring For integral cable sensors: 4-20mA Positive BLACK... -
Page 11: 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. -
