Temperature
The CTU temperature analog output signals is constant at 0 °C to 120 °C (32 °F to 248
°F) equal to 4 to 20 mA and 0 to 10 V DC.
Values of temperature (T) in the machinery being monitored can be calculated from the
measured analog current (mA) output signal of the CTU (terminals 11 and 12) using the
following equation:
120 (C - 4)
16
T =
Where as;
T = temperature level in machine (°C)
C = measured current output from CTU (mA) between 4 and 20 mA
Or
216 (C - 4)
16
+ 32
T =
Where as;
T = temperature level in machine (°F)
V = measured current output from CTU (mA) between 4 and 20 mA
The temperature (T) in the machinery being monitored can be calculated from the
measured analog DC voltage signal of the CTU (terminals 12 and 13) using the
following equation:
T = 12 x V
Where as;
T = temperature level in machine (°C)
V = measured voltage output from CTU (V) between 0 and 10 V DC
Or
T = (21.6 x V) + 32
Where as;
T = temperature level in machine (°F)
V = measured voltage output from CTU (V) between 0 and 10 V DC
