Description
Waterproof torque transducer DRWPL
DRWPL series torque transducers are fitted with a number of gaskets in compliance with international protection IP67.
The devices are also available with optional speed or angle detection for a host of applications. The integrated signal amplifier is powered with 12 V DC and outputs an electrically isolated analog signal of 0 to ± 10 V.
Features
- waterproof (IP67)
- contactless
- integral torque amplifier
- single supply voltage
- wide range of application
- small form
- low moment of inertia
- speed measurement (option)
- angle measurement (option)
