Single-supply strain gauge bridge amplifier circuit Design Notes: 1. Technological Science 1 Strain Gauge Laboratory Report By Akash Sherchan Student I. D. #: 1124433 University of Warwick Summary The strain gauge laboratory session had a lot of aims and one of the main aims was to provide us with experience in using circuits based on operational amplifiers and examine the characteristics of these circuits when they amplify DC signals. Mantracourt’s ICA family offers high stability and fast response strain gauge or load cell amplifier, converting a strain gauge input into a volt or mA output. After I finished wiring the strain gauge array for a load cell, I pulled the bundled circuit board out of its anti static bag. Understanding load cells is a matter of mechanical, electrical and electronical knowledge and it takes a lot of time (in fact now my job is teaching this at the university). For further information on strain gauge signal conditioning for load cells see ‘What is a Signal Conditioner? In-line Strain Gauge or Load Cell Analogue Amplifier (ILA) Strain Gauge Signal Conditioning for Load Cells (SGA/A&D) Miniature Strain Gauge Amplifier, Converts Load Cell to 4-20mA & 0-10V (ICA4H) Set of 4; In-Line Housing for Load Cell Amplifiers (ILE) Bridge Completion Module for the SGA (SGABCM) It’s sub-miniature design enables it to be fitted into the majority of transducers for a wide range of signal conditioning for strain gauges, load cells, pressure and torque transducers. Instrumentation signals (for example from Wheatstone bridge sensors) are often in the order of mV (millivolts) or less, and need to be amplified for processing via ADC. Strain Gauge Amplifier The circuit provides bridge voltage excitation and strain (∆R) sensing on a single compact board. The ICA family offers high stability and fast response strain gauge or load cell amplifier, converting a strain gauge input into a volt or mA output. Low tolerance resistors must be used to minimize the offset and gain errors due to the bridge resistors. p%��I_�!�ea��� (d) Accurate strain-gauge bridge measurements requir e an amplifier with a high common-mode rejection ratio and a low output offset. �ٳ�������� 2�KE�'C*���BD �1A��RF���B*4�(H�2Ɣ �K��l��`d�͒ф�o�I�ޏG��3�?4�lHwU&�B�� M��t� &��.f�b{�i��f�z�.���6s�k��w�Dq.N��$���x)�� 1��~��)���=��E,��P�b� endstream endobj 4 0 obj<> endobj 5 0 obj<>/ProcSet[/PDF/Text]/ExtGState<>>> endobj 6 0 obj<>stream Skip to main content.
