BCE14/15 Standard Specifications
Double/TRIPLE TACHOMETER TESTERs
The DMA BCE14 and BCE15 are laboratory computer-driven tachometer test systems for simultaneous testing of up to three tachometers and indicators used with turbine engines. DC motors with coaxial optical encoders, precision controlled by dedicated micro-processors and
quartz timing circuits, provide maximum accuracy and stability. The BCE14 is equipped with two independent drive heads and the BCE15 with three drive heads for helicopter instrument applications.
FEATURES
• Rotation speed can be displayed in %FS or RPM or both. deg/s, deg/min, rad/s, rad/min & Hz are also available.
• Speed values, rotation sense, transmission ratio & full-scale speed are independently selectable for each drive motor.
• User selectable limits are included for safe operation.
• The generators can be tested under resistive “Y” or “Δ “ loads. The results are compared with the selectable limits.
