Page 11: Introduction
Torque sensor Model 86403, -13, -23 1. Introduction 1.1 Intended use The torque sensors are not safety components in the sense of the intended use. Only use the torque sensor for the measurement of torques. This measured quantity is suitable for open-loop and closed-loop control functions. - Page 12 In this case you obtain a positive electrical signal at the sensor output. Wellenende Shaft end Figure 1: Torque, clockwise (looking towards the drive end) You can use model 86403, 86413 and 86423 torque sensors to measure both clockwise and counterclockwise torques. Shaft end Wellenende...

Page 15: Principle Of Operation
3.1 Mechanical structure Basically the sensors of the models 86403, 86413 or 86423 consist of a torsional shaft applied with strain gauges as a full bridge. Therefore, this shaft is used as the measurement element of the sensor, witch is supported by ball bearings. - Page 16 Model 86403, -13, -23 Torque sensor Seite 16...

Page 17: Installation
4. Installation 4.1 Preparing the installation Always use shielded cable with as low a capacitance as possible. burster can supply cables that have been tested with our sensors and satisfy instrumentation requirements. Relationship between sensitivity and cable length Note: With extension cables, the sensor sensitivity is affected by the cable length as a function of the bridge resistance and the conductor cross-section. -
Page 18: Mechanical Installation
Model 86403, -13, -23 Torque sensor 4.2 Mechanical installation Caution! Damage from excessive torques, bending moments or axial forces. Support the sensor while it is being fitted! Avoid dropping the sensor! Make electrical connections to sensor during fitting. Check the measurement signal. - Page 19 Torque sensor Model 86403, -13, -23 Connections with a clamping piece If you use a clamping piece, this clamping piece must be able to transfer the emerging torques safely. Connection with a parallel key Secure the hub against slipping out.

Page 20: Rotary Protection
Protect the sensor only at the threaded holes against rotation! Never use the cable for rotary protection! Protect the sensor’s housing against rotation. Therefore, the sensor models 86403 und 86413 have threaded holes on their front or lateral surface. threaded holes model 86403 model 86413 Figure 9: These threaded holes give you the ability to protect the sensor from rotation. -

Page 26: Static / Quasi-Static Torques
Model 86403, -13, -23 Torque sensor Function: excitation + signal + signal - external switch control excitation + internal external By applying negative Strain Gauge excitation, the measuring bridge is electrically detuned, so that at the output a measuring signal of 100% of the nominal value is available. -
Page 27: Speed Limits
Torque sensor Model 86403, -13, -23 6.5 Speed Limits Caution! Damages caused by high rotation speed! Only use the sensor for speeds below of the stated speed limit. Refer to data sheet 6.6 Angle measurement (optional) Note: Only with optional angle measurement! At angle or speed measurement, the pulses per revolutions are acquired. -

Page 29: Cleaning The Sensor
Torque sensor Model 86403, -13, -23 7.3 Cleaning the Sensor In order to avoid measuring signal fluctuations, remove the carbon dust from the sensor housing (depending on speed). Clean the sensor as described below, five times during the durability of the brushes and allow us to check the slip rings. - Page 30 Model 86403, -13, -23 Torque sensor Afterwards clean the slip rings Do this by using a fine cloth or a Q-tip, slightly moistened with spirit. Now, carefully clean brush-unit. Use a brush as well and if necessary blow off dust by using dry and oil-free air.
