Precision Strain Gauge type Load Cell are used for sensing the Torque developed by the Engines. Its rugged and rigid design of Power absorbing systems are ensured for long working life. This is achieved by electro less nickel plating to the most critical parts which are always in contact with cooling water. When the current flow through the field coils, then Magnetic field is produced. If the toothed rotor is rotated in the field, the magnetic flux changes and eddy current are produced in the end wall of cooling plate. These Eddy Currents buildup an opposite magnetic field and decelerate the rotor. The braking torque is transferred via the trunnion bearing mounted Body to the load cell. The dynamometer load is regulated by changing the excitation current.  High accuracy Strain Gauge Load Cell  Electro less Nickel plated water passages  Dry running is avoided by water flow switch.  Bi-directional operations  Low inertia of Rotor  Smooth running of Rotor  Rugged construction  Long Life service  Compact design DYNAMOMETER CONTROL UNIT (DCU) Dynamometer Control Unit (DCU) developed precise controller for Torque. It is in-house developed microprocessor based instrument with unbeatable reliability and best-in-class repeatability. DCU is well known for precise and fast action in controlling the Torque. Speed measurement is done using 60 teeth gear arrangement which is cost effective and highly accurate.  Highly precise Torque Control  Easy Loading & Unloading  Password Protected Program  Over Speed Protection  Over Torque Protection  Modbus RTU protocol  Current Retransmission O/P  Built-in Power Card  Analog and Digital Isolation
