KWR61N66 Joint Torque Sensor is a high-precision product powered by 9~24V DC and outputting digital signal RS485. The wiring method is that the red line corresponds to positive power supply, the black line corresponds to negative power supply, the green line corresponds to 485A+, and the white line corresponds to 485B -. In addition, this product can also output 0-10V, with the red line corresponding to positive power supply, the black line corresponding to negative power supply, the green line corresponding to positive signal, and the white line corresponding to negative signal. The outer diameter of this product is Φ 61mm, with a total height of 10mm, including the height of the built-in circuit board. For the production calibration testing of joint torque sensors, the calibration experimental measurement system includes a high-precision six and a half position instrument, a DC stabilized power supply, a calibration table, and weights. The elastic body is connected to the PCB, and torque calibration is performed by adding weights to the lever connected to the torque measurement sensor, thereby accurately fitting the torque coefficient of the joint. The range of this product is 66Nm, and the detection range of repeatability, nonlinearity, and hysteresis is within 0.5% F.S. It can withstand 200% safe overload and 300% ultimate load. In addition, when subjected to lateral torsional loads, the maximum lateral ultimate bending moment of this product is 66Nm, the torsional stiffness is within 25.4kNm/Rad, and the maximum torsional angle does not exceed 0.03 °. The lateral ultimate load of the sensor is 11.5kN; the axial load limit is 6.39 kN. The applicable working temperature range of this product is between -10 ℃ and 80 ℃, and it can adapt to various complex environments.
KWR63N49 torque sensor is a precision measurement and control device designed specifically for the industrial and commercial robot fields.

It can measure static torque in real time and accurately, and output RS485 signals. This product has the characteristics of high measurement accuracy (comprehensive accuracy ≤ 0.5% FS after calibration), good range stability (temperature self compensation from 0 ℃ to 60 ℃), and sensitive response (minimum resolution of 0.05Nm). It can provide reliable “force perception” capability for rotating machinery systems, helping customers achieve intelligent control and efficient management.
Crash Dummies are vital in the field of automotive passive safety. There are many loadcells and displacement sensors in the dummy. Sunrise Instruments (SRI) has more than 30 years of experience in designing and manufacturing dummy sensors. SRI’s dummy sensors are used in most crash labs around the word. These sensors help people accurately measure the force, moment and displacement of crash dummy body parts during crash testing.
In the field of vehicle safety, a crash wall integrated with Crash Wall Load cells is an essential equipment. Each Crash Wall Load cell measures forces in X, Y, Z directions during vehicle impact test.
Two types of crash wall load cells are available: standard and lightweight versions. The standard version has a sensor capacity of 300 or 400kN, for digital or analog output versions respectively. These can be used to configure a Full Width Rigid Barrier. The lightweight version has a capacity of 50kN and can be integrated into a Mobile Progressive Deformable Barrier.
