We are offering accelerometer calibration system. 1. Overview a sensor's frequency response and sensitivity is a very important technical indicator for a its designing and its vibration signal measurement. The system is designed for the calibration of the accelerometer's frequency response curve and sensitivity. The calibrating procedure is automatically controlled by a computer. The system is used to measure the frequency and amplitude of a standard reference accelerometer and the sensor to be calibrated. The sensor's frequency response curve and sensitivity is thus calibrated by comparison of the different measurements (the so-called back-to-back method). the system can be used in research institutes, laboratories of vibration research, and for the design and production of sensors. the system can also calibrate the sensitivity and frequency response curve of velocity sensors. Velocity sensors are widely used in petroleum exploration, machinery vibration monitoring in factories, etc. 2.

It can produce high quality experimental results with this device. Other tests can be added to the device as needed. The strain instrument inside the device can connect to a computer where data acquisition and processing can be performed. this product is designed with enclosed steel frame and cast composition with careful surface treatment. It is a durable fastening structure. For each type of experiment, the product equips with specimens and surface treatment samples and accessories. system composition and principle the system is composed of base, pure bending specimens, sensors, strain instrument, strain gage, wires and so on. The strain instrument can connect to a computer where data can be processed. Through the electrical test method, a few basic parameters in mechanics of materials can be measured and analyzed, and the results can be compared with the theoretical values. the basic principle of this strain-stress electrical measurement method: measuring a specimen's surface strain with strain gage, then the specimen's surface stress state is determined according to the strain-stress relationship. The strain-stress electrical measurement method is not only used to validate the basic theory of mechanics of materials, to measure the mechanical properties of materials, but also is a major engineering testing means for solving engineering problems. It provides a good experimental basis for scientific research. contents of experiment (1) normal stress regularity of distribution on cross sections of pure bending beams (2) strain gage sensitivity coefficient calibration (3) elastic modulus and poisson's ratio determination (4) eccentric tension (5) bar stability (6) determination of the size and the direction of the principal stress (7) measurement of bending moment and torque separately under the combined action of the bending and torsion (8) equal strength tests on variable cross-sections (9) bending normal stress test on equal strength beams specifications experimental device dimension: 700x475x1080mm (27.56x18.70x42.52") maximum loading: 8kn maximum loading displacement: 30mm (1.18") loading speed: 0.12mm/r the handwheel load torque: 0~2.5n.m weight: 70kg pure bending beam dimension: 700x20x40mm (27.56x0.79x1.58") maximum loading: 4kn elastic modulus: e=190~210gpa poisson's ratio: âµ=0.26~0.33 calibration beams dimension: 700x15x25mm (27.56x0.59x0.98") maximum loading: 4kn elastic modulus: e=190~210gpa poisson's ratio: âµ=0.26~0.33 three-point deflectometer dial indicator measuring range: 0~10mm resolution: 0.01mm support span: 200mm seamless steel pipe (hollow shaft) outside diameter: 40mm (1.58") inside diameter: 32mm (1.26") length: 345mm (13.58") length of the sector arm: 240mm (9.45") elastic modulus: e=190~210gpa poisson's ratio: âµ=0.26~0.33 preload: >100n maximum loading:
