产品信息 线性放大器应变计传感器放大器数字显示模块电压/ 4-20mA输出限制旅行简单trimpot控制 Signal conditioning is required where the output of a transducer needs to be boosted or changed into a form suitable for the monitor or logging device which will be used. Our digital display units have a built-in monitor device in the form of the digital display as well as analogue output. Both E308 ａnd E309 have high ａnd low limits with voltage-free relay outputs. The E308 has a shunt calibration facility to enable calibration checks to be made. A very wide range of gain adjustment ensures that our amplifiers are compatible with the vast majority of LVDT ａnd strain gauge sensors available from any manufacturer. Although they have a digital display, these units are entirely analogue ａnd are configured using switches ａnd potentiometers, there is no set-up software to learn.
