Crane Electronics: RTA / RTD
The RTA and RTD series of rotary torque transducers provide accurate torque measurement at speeds of up to 50,000rpm and range from 0.2Nm up to 5000Nm. The series has integral signal conditioning providing a ±5V output and they also provide 60 TTL pulses for additional speed measurement. For speeds below 7000rpm, a 360-pulse option is also available. The RTA and RTD series of single and dual range torque transducers have turndown ratios of 10:1 or 5:1. RS232 communications is an added option, along with a range of digital readouts for torque, speed and power if required.
