LCD-20，桥接放大器

品牌：美国Cooper        型号：LCD 20桥接放大器

LCD20智能应变计电桥放大器是一种紧凑、可堆叠的微处理器单元，专门设计用于控制和监控称重应用。它提供了一个灵活的连接到大多数称重传感器，压力或应变计在广泛的灵敏度范围。它还提供隔离电流4-20毫安和电压0-10伏模拟输出和两个数字输入。可配置两个设定点继电器来设置阈值，如净阈值、总阈值、峰值和谷值。由广泛的直流电源供电，为DIN轨道放大器提供了2个部分的螺纹接头，以减少现场停机时间。

LCD20适用于应变计和其他比率公制传感器，并将支持6线输入，以补偿屏障和电缆损耗。它在工厂校准为mV/V，支持10点用户校准至所需的工程单位，允许在所选单位中配置模拟和继电器输出。配置选项通过手持程序员或PC工具包软件。

模拟输出和继电器与现有采集和控制系统接口，使该装置成为任何集成仪表系统的理想合作伙伴。

The LCD20 intelligent strain gauge bridge amplifier is a compact, stackable microprocessor based unit specifically designed to control and monitor weighing applications. It provides a flexible connection to most load cells, pressure or strain gauges over a wide range of sensitivities. It also provides isolated current 4-20mA and voltage 0-10V analogue outputs and two digital inputs. Two set point relays can be configured to set thresholds such as net, gross, peak and valley. Powered from a wide ranging DC supply, the DIN rail amplifier is supplied with 2 part screw connectors for minimal downtime onsite.

The LCD20 is suitable for strain gauges and other ratio-metric sensors and will support 6 wire input to compensate for barrier and cable losses. It is factory calibrated to mV/V and supporting 10 point user calibration to desired engineering units which allows configuration of analogue and relay outputs in the chosen units. Configuration options via handheld programmer or PC Toolkit software.

The analogue outputs and relays interface to existing acquisition and control systems making this unit an ideal partner for any integrated instrumentation system.
