LORENZ放大器GM80 106781产品介绍
测量放大器可以处理 ±3.3 mV/V 的传感器应变仪 (SG) 信号和 ±10V 和 0/4 ... 20 mA 的有源信号。
测量放大器可以通过电池或蓄电池操作移动使用，但也可以配备外部主适配器。
通过使用高精度放大器和组件、16 位 A/D 转换器和快速微控制器，确保了高测量精度和快速测量速率。
一个多功能的可配置数据记录器存储一系列带有日期的测量值和多达 15288 个测量值。
测量值或记录值可以通过 USB 或 RS232 接口输出到计算机或打印机。
十个参数集可用于传感器。其中，在每种情况下，校准数据、传感器名称和物理单位都被存放。
皮重、取最小值/最大值等功能。并删除最小/最大。测量期间可用。
数据记录器或接口可以通过额外的触发输入进行外部控制。
在低测量速率下，应变计电源时钟节电。如果 GM80 未处于测量模式，则设备会在三分钟后关闭。
The measuring amplifier can process sensor strain gauge (SG) signals of ±3.3 mV/V and active signals of ±10V and 0/4 ... 20 mA.
The measuring amplifier can be used mobile by battery or accumulator operation, but can also be supplied with an external main adapter.
A high measuring accuracy combined with fast measuring rates is ensured by the employment of highly precise amplifiers and components, 16 bit A/D converters and a fast microcontroller.
A versatile configurable data logger stores a series of measurements with date and up to 15288 measured values.
Measured values or logging values can be expelled to a computer or printer via the USB or RS232 interface.
Ten parameter sets are available for sensors. Therein, in each case,the calibration data, the sensor designation and physical unit are deposited.
Functions such as tare, fetch min./max. and delete min./max. are available during the measurement.
The data logger or the interface can be controlled externally via an additional trigger input.
At low measuring rates, the strain gauge supply is clocked power-saving. If the GM80 is not in measuring mode, the device shuts off after three minutes.
