Control Accuracy and Stability

(GM / AM / NM / LM / AH / LH / LU / GR / AR / LR)

Belimo non-spring return actuators are designed with a unique non-

symmetrical deadband. The actuator follows an increasing or decreasing

control signal with a 75 mV resolution. If the signal changes in the

opposite direction, the actuator will not respond until the control signal

changes by 175 mV. This allows these actuators to track even the

slightest deviation very accurately, yet allowing the actuator to “wait” for a

much larger change in control signal due to control signal instability.

The …MFT US actuators are designed with a unique non-symmetrical

deadband. The actuator follows an increasing or decreasing control

signal with a 80 mV resolution. If the signal changes in the opposite

direction, the actuator will not respond until the control signal changes by

200 mV. This allows these actuators to track even the slightest deviation

very accurately, yet allowing the actuator to “wait” for a much larger

change in control signal due to control signal instability.

All MFT actuators have built-in

brushless DC motors which provide better

accuracy and longer service life.
