Low torque sensor offers precise dynamic measurement of rotary and static torque

10-03-2020 | Saelig | Test & Measurement

Saelig Company has introduced the TorqSense ORT 230/240 Low Torque Sensor, which provides a precise dynamic measurement of rotary and static torque from 10mNm to 100Nm for signal bandwidths up to 50kHz. The new torque sensors replace the previous E200 ORT series and provide all-new electronics with notable performance increases in resolution, frequency response, decreased sensor current consumption, and faster digital data throughput. The absence of brush gear and fixed electronics enables high-speed operation with a continuous rating up to 30,000rpm standard.


The devices precisely measure bi-directional rotary or static torque and can also be furnished with speed sensors for monitoring dynamic applications, allowing direct measurements of transmitted power. The transducers need no external instrumentation and include their own built-in test capability. Their compact size makes them perfect for employment in applications where there is limited space for additional equipment. Analog voltage outputs are standard, with current outputs offered as an option. TorqView software, provided free, enables the ORT240 series to be connected to a PC via USB (optional) or RS232 so that configurations can be modified, and to show torque, speed, and power.


This new generation of optical rotary torque sensors is intended for applications where accurate, dynamic measurement of rotary and static torque, with high resolution so that even ultra-short torque peaks and troughs can be reported. Typical applications comprise profiling the acceleration and deceleration of high-speed motors, collecting data from repetitive scientific experiments, controlling microsystems and miniature machinery, and testing industrial machinery to destruction.
