“…The load cell is a strain gauge that implements the "Jembatan Wheatstone" concept. Four resistors in "Jembatan Wheatstone "circuits with an excitation voltage applied across it [23]. One of the resistive components is the strain gauge, which has unknown resistance depending on the strain occurring in the indicator.…”

The force balance system uses the whitestone bridge concept to read the airfoil aerodynamic lift and drag forces while also having a function to control the airfoil angle of attack. It is designed for low subsonic wind tunnels, especially for educational purposes. The system uses Arduino as the microcontroller to read the force data from the load cell sensors and gives commands to the rotary motor stepper to change the airfoil angle of attack. Arduino is combined with a novel mechanical linkage system designed and studied to ensure the sensors can read the correct airfoil lift and drag forces. The angle of attack is controlled with a smartphone to decide the degree of airfoil. The reading of the system is validated using spring balance that pulls the system with magnitudes of 1,1.5, 2, 2.5, and 3 kg in some pulling force angle. The results show that the reading of the system is accurate compared to the theoretical results, with an average error of 2 %. The force measuring tool on the airfoil is the first step in a series of steps to produce the final project, namely the wind turbine. Research suggests that the load cell must be positioned correctly so that the sensor reading error can be increased again. The stepper motor must be turned off the bottom shaft to prevent the airfoil from rotating.

To effectively obtain the downforce of the gauge wheels in real time, mechanical models of the interaction among the ground, gauge wheels, gauge wheel arms, and depth adjustment lever were constructed. A measuring method was proposed for monitoring the downforce through a two-dimensional radial sensing device, and a corresponding prototype was designed. Through simulation analysis of the sensing device with ANSYS, a 45° angle was determined to exist between the strain gauge axis and the sensing device axis, and the Wheatstone bridging circuit of R1+R3−R5−R7 (R stands for resistance strain gauge, different figures represent the strain gauge number) and R2+R4−R6−R8 was adopted. According to performance and calibration tests for the sensing device, the maximum interaction effect between the X and Y axes was 2.52%, and the output signal was stable and consistent. The standard error of the slope of the fitting equation of the downforce calculation model is 0.008. According to the field test, the average downforce of the gauge wheels was 1148, 1017, 843, and 713 N, at different sowing speeds of 6, 8, 10, and 12 km/h, respectively. The coefficients of variation were 0.40, 0.41, 0.62, and 0.71, respectively. The results indicate that the downforce fluctuation of the gauge wheels became more severe with increasing planting speed. Both the strain simulation analysis and field test verified that the measurement method is accurate and reliable, the performance of the sensing device is stable, the measurement method and sensing device meet the application requirements and lay a foundation for the research of accurate and stable control of downforce of no-till planter.

“…Strain gauge yang mengalami tekanan (T) akan meningkatkan resistansinya, sementara yang mengalami kompresi (C) akan mengurangi resistansinya. Ketidakseimbangan ini menyebabkan jembatan wheatstone, yang merupakan komponen dalam load cell, menghasilkan perbedaan tegangan (sinyal) yang sebanding dengan beban pada load cell, yang dapat diukur pada titik A dan B [9], [10].…”

Proses pengemasan semen PCC di PT. Cemindo Gemilang Plant Bengkulu menggunakan alat bernama Rotary Packer 8 SRC. Alat ini memiliki kemampuan untuk mengemas 8 kantong semen secara simultan. Sensor encoder digunakan dalam rotary packer untuk memantau proses pemutaran, serta sudut posisi atau putaran selama pengemasan semen. Jenis sensor encoder yang digunakan adalah jenis inkremental, yang merupakan jenis rotary encoder yang dapat mengukur perubahan sudut. Rotary Packer 8 SRC juga dilengkapi dengan load cell untuk mengukur berat timbangan dari setiap kantong yang diisi. Load cell yang digunakan adalah jenis Bending Beam dengan tipe Z6FC3 yang diproduksi oleh HBM, dengan kapasitas pengukuran hingga 500 Kg. Penelitian ini bertujuan untuk menganalisis sistem kerja sensor encoder dan load cell pada sistem pengemasan semen. Kinerja kedua sensor dianalisis dengan membandingkan hasil pengukuran dengan batas toleransi 5% yang telah ditetapkan. Berdasarkan hasil pengukuran, nilai posisi sudut discharge bag tertinggi tercatat pada posisi 317º dengan nilai error sebesar 1,6% pada sensor encoder. Nilai timbangan tertinggi adalah 50,50 kg atau terdapat error 1% pada sensor load cell. Nilai error pada kedua sensor tersebut tidak melebihi batas toleransi yang telah ditetapkan sehingga disimpulkan kedua sensor masih berfungsi dengan baik.
