PCB Piezotronics, Inc., a global leader in vibration, acoustic, pressure, force, and torque sensors, is pleased to announce the introduction of the new Series 4115K Rotary Torque Transducer. Provided by PCB Load & Torque, Inc., a PCB Group Company, these transducers use non-contact, rotary transformers for sending excitation voltage to, and receiving measurement signals from, the strain gage instrumented rotating sensor element. Their unique flange and splined shaft design, which conforms to AND 10262 & 20002, makes these units ideal for use in torque studies on aerospace hydraulic motors and pumps. Other applications include dynamometers, drive shafts, transmissions, fans, and electric motors.

In addition to the torque output signal, an optional pickup provides an output proportional to speed. These units feature high torsional stiffness and low rotating inertia. Models are available with several measurement ranges and speeds up to 15,000 rpm.
