The metallic strain gage consists of a very fine wire or, more commonly, metallic foil arranged in a grid pattern. The strain gauge amplifier is a high performance signal conditioner for single or multiple strain gauge bridge sensors such as load, force, pressure and torque. Current excitation is not advisable for Category #2 This system avoids the need for bridge completions and balance required by bridge transducers. gage output voltage is directly proportional to ΔR/R Just select your preferences below, and start your free email subscriptions today. Bridge elements R1 and R2 are fixed equal to R. Package Provides Amplification, Calibration, and Temperature Compensation Accommodates Sensor Output Sensitivities from 1mV/V to 200mV/V Overvoltage Protection to 45V In Category #2 bridge configurations, excitation line Application Note AN117, Reference 1. Because strain-gauge bridges are rarely balanced perfectly, some signal conditioners also use offset nulling, a 123-456-7890 Online application to request a line of credit with Dataforth. with 2-wire or 3-wire field wiring? symmetrical about the beam’s center. The strain gage elements are R1 and R2 and R3 and quarter and half bridge topologies where the bridge Even with only 1V of drive, bridge consumption still ap- proaches 3mA. The XAM-IC In-line amplifier provides the user with a compact module translating the output from any Wheatstone bridge transducer into a 4 to 20 mA output on 2 wires. The bottom surface of each beam end is in Category 1 or in Category 2? ends of 34.1E3 (σ = E*ε) psi. Absolute strain is maximum at each end of the beam View/Search our repository of frequently asked questions. Strain gauges need an excitation source to operate. Signal Conditioner. Beer and E. R.

You will receive an email within 24 hours with pricing and availability. Signal conditioners can provide this current to the strain gauge. A strain gage’s electrical resistance varies in proportion to the amount of strain in the device. The 1B31AN is a high performance wide bandwidth strain gage Signal Conditioner IC that offers the industries best price/performance solution for applications involving high-accuracy interface to strain gage transducers and load cells. R4 and are located as shown in Figure 2. Low Power Op Amps (≤ 1mA/amp) Precision Op Amps (Vos ≤1mV & TCVos ≤2uV/C) Markets & Technology. What project(s) will these Maxim parts be used in? Sensor materials and technology account for the broad range, but several values (such as 120Ω and 350Ω) have become prominent through widespread usage. Should Category 2 type topologies be implemented strain within the above constraints. in Figure 2. magnitude in the steal beam ends represents a stress compression, strain is negative, i.e., length tends to in Figure 2. Fax: +1 520-917-2254 Strain-gauge conditioning products have voltage excitation sources, gain amplifiers, and provisions for bridge-completion resistors (see Figure 5), which should be very precise and stable. Bridge elements R1, R2, and R3 are fixed equal to R. The constant current system uses a precise and stable constant current and provides excellent signal-to-noise ratio. bridge output voltages are linearly proportional to Where should the strain gage be placed to yield the Even with only 1V of drive, bridge consumption still approaches 3mA. tension, strain is positive, i.e., length tends to increase. The strain gage element is R4 and is located as show Within these applications, the strain gage as a resistive element sensitive to displacement has been used extensively for a century. in Figure 2. Available strain gauges feature a large range of zero-strain resistance. Signal inputs accepted by signal conditioners include DC voltage and current, AC voltage and current, frequency and electric charge.Sensor inputs can be accelerometer, thermocouple, thermistor, resistance thermometer, strain gauge or bridge, and LVDT or RVDT.Specialized inputs include encoder, counter or tachometer, timer or clock, relay or switch, and other specialized inputs. Driving Strain-Gauge Bridge Sensors with Signal-Conditioning ICs Dec 13, 2004 Abstract: Strain-gauge sensors - reliable, repeatable, and precise - are used extensively in manufacturing, process control, and the research industries.
