Model: CJ-NJ01
Introduction
CJ-NJ01 dynamic torque sensor is based on proprietary technology developed on the strain bridge, special sensors for measuring torque, speed parameters. This series torque sensor uses strain bridge measuring technology, using a set of toroidal transformer provides a non-contact power supply, micropower signal coupler instead of toroidal transformer for non-contact signal transmission, effectively overcome the inductive interference and harmonic energy toroidal transformer toroidal transformersignal mutual interference, while the output spikes into a square wave signal, etc. Therefore, this series torque sensor can be a long, high-speed operation. These series can be used for dynamic measurements, variety of installation design, takes users great convenience.

Torque Sensor Working
Code wheel and rotating body are integrated to rotate. Photoelectric switch through the photoelectric effect, do gate processing, the output of a high-low pulse signal. Pulse signal proportional to the speed. To achieve the transformation of the physical speed of the electrical signal

Installation Method
1. High-measuring sensor and the center of the shaft diameter, to be installed.
2. Use two couplings or flange, the sensor is mounted between the power plant
and the load.
3. were adjusted power equipment, load, high center of the sensor and coaxial
degree requirement is less than
0.01mm, and fix and tighten reliable, does not allow loose, when the
small-scale or high-speed sensor, to ensure strict center connections and high
concentricity. Doing so may cause damage to the sensor and measurement
error.
Choice of rigid or flexible coupling 4. When connected, the shock can not be
guaranteed concentricity greater or installation requirements (greater than
0.05mm, less than 0.02mm), recommended Rao, elasticity or universal joint
couplings; and the sensor base and the support frame
It proposes to add between about 10mm rubber pad to reduce the damage to the
sensor when the sensor is installed in a different mind.
5. The power source and the load equipment must be fixed reliably avoid
vibration; sensor support base must have a certain strength. To ensure the
stability of the installation to avoid excessive vibration. Doing so could
cause instability in the measured data, affect the measurement accuracy.
6. The coupling should be against the shaft shoulder across the
sensor. Sensor is a precision measuring instrument, installation of
non-impact, beating and other violent impact.
7. When the sensor is recommended when using the horizontal installation, make
other angle of installation, please carefully install the sensor is not allowed
with excessive axial and bending moment or otherwise, may affect the use of the
sensor and even cause damage to the sensor.
Common Signal Type and Related products
