全桥传感器展开版基于先进的传感器技术

Micro-Measurements®, a Vishay Precision Group, Inc. (VPG) brand, today announced that it has expanded its product line of Transducer Class® full-bridge strain gauges based on Advanced Sensors technology

与粘结多个单独的应变仪相比,该设备具有多种优势,现在该设备具有更小,更高的电阻模式,可用于各种弯曲和扭矩/剪切应用。

应变计已使用多年,并在许多类型的精度力测量传感器,包括压力,扭矩,负载和位置发现的基本感测元件。 惠斯通电桥电路是最常用的感测应变的电阻变化。 此电路需要连接成一个串联/并联配置4电阻元件。 一个,两个,或四个应变计可作为四个电阻元件,具有精密电阻构成部分的配置。 全桥电路(具有四个有效应变计)为最高的测量灵敏度和最好的外部温度取消。

Built using Micro-Measurements” Advanced Sensors strain gauge technology, the S5056, S5020, S5046, and S5047 strain gages offer improved grid-resistance tolerance and grid-to-grid temperature matching compared to traditional gages. Micro-Measurements offers a wide range of pattern configurations and resistance ranging from 350 O to 20 kO. The addition of gold-plated solder pads improves lead wire attachment and solder-joint reliability, reducing the chances of solder pad oxidation prior to attaching the lead wires.

与键合多个独立应变片相比,全桥器件可提供简化,更精确的对准和减少键合操作。 惠斯通电桥电路的所有四个有源臂形成在一个载体上,从而允许整个电桥一次结合。 所有的桥内连接都集成在模式中,从而消除了桥内焊接。

“Eliminating intrabridge wiring and soldering helps to reduce zero TC problems,” said Ron Zukerman, Micro-Measurements Advanced Sensors manager of marketing and sales. “With no internal bridge wiring required, soldering is reduced to just four instrument wire connections, which greatly improves reliability. In addition, with all four arms of the Wheatstone bridge being manufactured simultaneously from a single piece of foil, grid-to-grid thermal characteristics are more closely matched, and thermal output is cancelled in the bridge circuit.”

微测量传感器可有多种尺寸,配置和安装技术。 对于S5056,S5020,S5046和S5047,将先进的传感器生产线,使原型,单件和大批量制造能力。

样品和量产批量全桥感应器现可提供,有六个星期的原型样品和12周标准订货的供货周期。
