(iPad, vibration, rotor-balancing, portable balancer)

iRotorBalancer is a technical tool for balancing of rotating machinery in single-plane and two-planes. This iPad application connects to the Rotor Balancing Kit to collect the vibration Amplitude and Phase with the accelerometer & tachometer, and calculates the correction balancing weights and angular positions. Following the guidance of iRotorBalancer, there is no need to go through complicated and tedious balancing calculation again.

PDF report option is available after each balancing work. Users can easily generate rotor balancing report including test information, machine image, vibration before and after balancing, correction weight information, custom note, GPS location and signature. PDF report can be saved and organized based on plant and machine in local report manager, or exported via email or wirelessly printed.
