VISHAY称重变送器WST-3产品介绍
WST 3 是一款高性能变送器，专为通过应变计传感器进行工业称重和测力而设计。仪器的前面板上有功能键和带背光的显示窗口。
正常操作时，实际测量值和继电器状态显示在窗口中，但也可以选择显示例如操作状态和设定级别值。
WST 3 为传感器提供激励电压，并将模拟传感器信号转换为具有极高分辨率的数字测量信号。通过参数控制计算，它会产生内部测量值，这些值可以显示在显示屏上，并用于控制模拟输出的电流或电压信号。
包括用于监控输入信号或一些内部测量值的功能。监控状态可用于控制两个输出继电器。
WST 3 可以作为从属单元并入不同类型的网络中。可以通过 Profibus 和 Modbus 与控制单元/PLC 进行通信。或者，Modbus 输出可用于将测量值传输到外部显示单元。
网络可用于设置参数值，但也可以从仪器前面板进行设置。
WST 3 内置于紧凑型外壳中，可轻松安装在 DIN 导轨或平面上。仪器输入和输出彼此电隔离。
WST 3 is a high performance transmitter, designed for industrial weighing and force measuring by means of strain gauge transducers. At the front panel the instrument has function keys and a display window with backlight.
By normal operation the actual measurement value and the status of the relays is displayed in the window, but display of for example operation status and set level values can also be selected.
WST 3 supplies the transducer with excitation voltage and converts the analogue transducer signal to a digital measurement signal with very high resolution. By parameter controlled calculations it produces internal measurement values, which can be presented at the display and used to control the current or voltage signal at the analogue output.
Functions are included for supervision of the input signal or some internal measurement values. The supervision status can be used to control the two output relays.
WST 3 can be incorporated as a slave unit in different types of networks. Communication with the control unit/PLC can be performed via Profibus and Modbus. As an alternative the Modbus output can be used to transmit measurement values to external display units.
The network can be used for set-up of parameter values, but set-up can also be performed from the instrument front panel.
WST 3 is built into a compact enclosure, which is easily installed on a DIN-rail or a flat surface. The instrument inputs and outputs are galvanically isolated from each other.
