Data Sheet Typ 8645 - 1

Direct contact: +49-7224/645 -45 or -78 Delivery: ex stock | Warranty: 24 months Torque Sensor rotating, non-contact transfer MODEL 8645 Highlights Measuring range 0 ... 2.5 N.m to 0 ... 500 N.m E xtended temperature range -40 °C ... 85 °C H igh axial forces allowed Integrated amplifier Model 8645 with round shaft Areas of application A utomotive (steering, gearing, motors) T extile machines P umps, mechanical conveying technology F itness and workout gears, household appliances Product description This sensor uses a non-contact and maintenance-free technology to convert the torque into an electrical signal. The nickel steel shaft is conditioned with a permanent magnetic pattern. Apart from this, no other components such as strain gages or wiring are required on the shaft. The magnetic pattern changes as a result of the torque being measured. This produces a measurement signal that is dependent on the torque. Via the integrated amplifier, the sensor supplies an output voltage of 0.5 ... 4.5 V. The zero point is at 2.5 V, which makes it easy to evaluate the direction of torque. burster Sensors and Process Instruments – Technical changes reserved. All data sheets at www.burster.co
