Acceleration (g) and Acceleration Enveloping (gE)
Values of vibration (V) in the machinery being monitored can be calculated from the
measured analog output current signal of the CTU (terminals 14 and 15) using the
following equation:
S (C - 4)
16
L =
Where as;
L = vibration level in machine (gE, g, mm/s, IPS)
S = full RANGE scale (gE, g, mm/s, IPS) of the CTU
C = measured current output from CTU (mA) between 4 and 20 mA
The vibration level (L) in the machinery being monitored can be calculated from the
measured analog DC voltage signal of the CTU (terminals 15 and 16) using the
following equation:
V x S
10
L =
Where as;
L = vibration level in machine (gE, g, mm/s, IPS)
V = measured voltage output from CTU (V) between 0 and 10 V DC
S = full RANGE scale (gE, g, mm/s, IPS) of the CTU
