Series 5300D

PCB^® Series 5300D TORKDISC^® In-line Rotary Torque Sensor Systems are designed for test applications requiring a robust rotary torque transducer where axial space is at a premium. Onboard, the transducer is a field proven electronic module that converts the torque signals into a high-speed digital representation. Once in digital form, this data is transmitted to a non-contacting pick-up loop, with no risk of noise or data corruption. A remote receiver unit converts the digital data to a high-level analog output voltage, and a serial digital output.

Series 5300D incorporates dual high level analog outputs, AC and DC coupled, providing both static and dynamic torque measurement capability that can be recorded separately and independently scaled; which is particularly beneficial when high DC levels are present or when low levels of AC content is of particular interest. Series 5300D also features industry leading DC bandwidth to 8500 Hz, resulting in increased dynamic response characteristics. The DC coupled output features an 8-pole low pass elliptical filter with user selectable frequencies for minimal roll off at each filter selection. A 2-pole Butterworth high pass filter with a wide range of user selectable cut off frequencies is included with the AC coupled output.

As with all PCB^® instrumentation, these sensors are complemented with toll-free applications assistance, 24-hour customer service, and are backed by a no-risk policy that guarantees total customer satisfaction or your money refunded.

Note: [1] Extraneous load limits reflect the maximum axial load, lateral load, and bending moment that may be applied singularly without electrical or mechanical damage to the sensor. Where combined extraneous loads are applied, decrease loads proportionally. Request Application Note AP-1015 regarding the effects of extraneous loads on the torque sensor output.

The robust construction, high stiffness, and low rotating inertia of the TORKDISC^® make it ideal for applications such as chassis and engine dynamometers. The TORKDISC^® system consists of a short coupled flange mounted rotating sensor, a stator assembly, and a signal conditioning module. Torque is measured using a unique strain gage structure within the rotating flange. The measurement signal is then digitized, and is transmitted without wires to the receiving antenna. The signal is conditioned to an independent AC and DC coupled voltage analog outputs.
