Product Description

Magtrol’s SBB15 Signal Breakout Box is designed to assist in the monitoring of speed, torque, and index signals obtained from either a Magtrol dynamometer or torque transducer. The easy-to-use SBB15 is simply inserted in series between a Magtrol controller and any Magtrol dynamometer or torque transducer. Connections are made via D-Sub 15 signal cables.

Speed, torque, and index signals are outputted through BNC connectors to an oscilloscope or other DAQ instrumentation device. Switching to the external encoder will switch the Tach A, Tach B, and Index signals, while the Torque signal will still be passed through from the dynamometer or torque transducer. The SBB15 Signal Breakout Box is a convenient and reliable accessory that reduces the necessary wiring required for signal monitoring.

Features

  • Two D-Sub 15 Connectors: provides an in-line connection between a Magtrol DSP Controller and a dynamometer or a torque transducer
  • Four BNC Connectors: provides easy access to Tach A, Tach B, Torque, and Index signals for connecting to an oscilloscope or other data acquisition (DAQ) device
  • Sturdy Assembly: packaged in an extruded aluminum case with metal mounting flanges
  • An external encoder input is provided for connecting high resolution encoders
  • A slide switch allows switching between a torque transducer and an external encoder

                    [post_content] => The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale, depending on size and system configuration.

Operating Principles

The PB Series - Powder Dynamometers contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction between rotor and stator. The Powder Dynamometers (PB) produce their rated torque at zero speed. The element to be tested can be loaded at standstill to determine the starting torque.

Optical Speed Sensor
Each PB Series Dynamometer has a standard optical speed sensor. PB 43 has an optical speed sensor with a 30 PPR (Pulses Per Revolution); PB 65, PB 115 & PB 15 has an optical speed sensor with a 60 PPR. For higher speed resolution in low speed applications, Magtrol offers a 600 PPR or 6 000 PPR encoder as an option.
