Hagstraße 10 · 74417 Gschwend w w w.eth-messtechnik.de Datasheet Torque sensor 27 torque ranges from 0,02 Nm up to 20.000 Nm precise measurement of torque, rpm and angle of rotation Option „F“ with base Alternative fastening option, enables simplified attachment! Easy to assemble! Alignment in the longitudinal axis using a parallel key, oriented and unmistakable installation (for example after recalibration) by means of parallel pins Accessory mounting adapter Precise peak height adjustment to a desired level. Hole pattern is the same as option with base. Features • contactless signal transmission • integral signal amplifier • low moment of inertia • rpm measurement (optional) • angle of rotation measurement (optional) • advanced electromagnetic compatibility (EMC) • adjustable output level for rpm and angle signal (5 - 24 V) • larger rpm range for rpm and angle measurements • frequency output 10 kHz ± 5 kHz • larger input voltage range (10 - 28,8 V) • compact dimensions, universally applicable • strain gauge technology • option base • accesory mounting adapter • 0.05% linearity error option Subject to change without notice Series DRVL torque sensors are suitable for lab and industrial applications because of their small size and multiple mounting options. As supply voltage and output signal are transmitted without contact, the device can operate continuously with low wear and largely maintenance-free. These sensors are also available with optional rpm and angular measurement for a host of applications. The integrated signal amplifier is powered with 10 - 28,8 V DC and outputs an electrically isolated analog signals of 0 ± 10 V and 10 kHz ± 5 kHz The standard version has smooth shaft ends, several types are available with optional parallel keys (see table). A factory calibration certificate with 25% increments (left, right) is included in the scope of deliver
