Product Details
SLFN+ 50-200Nm 0.1%FS 15000rpm high-precision High Speed Torque
Measuring Flange for Rotating Shafts
Torque sensors
SLFN/SLFN+ sensor is a general-purpose sensor, which is suitable
for all rotating power systems with sufficient distance between
power equipment and load. Meanwhile, power equipment and load are
relatively independent bodies, so coupling is required to install
the sensor between power equipment and load.
Characteristic
- Built in digital measurement signal conditioning unit, through
contactless transmission, the data is directly output in standard
analog or digital signal mode
- Strong anti-interference ability
- The rotor rotates in the stator ring, no mechanical bearing is
allowed, so there is no wear.
- High precision magnetoelectric angle / speed measuring unit, dust
and moisture proof
- Parameter identification, setting, measurement and zero balance of
sensor are realized through RS-485 interface
- Very small axial size compact flange flange connection design
- Digital non-contact signal transmission, no bearing, no
maintenance, system self-test function
