VISHAY稱重變送器WST-3產品介紹
WST 3 是一款高性能變送器，專為通過應變計傳感器進行工業(yè)稱重和測力而設計。儀器的前面板上有功能鍵和帶背光的顯示窗口。
正常操作時，實際測量值和繼電器狀態(tài)顯示在窗口中，但也可以選擇顯示例如操作狀態(tài)和設定級別值。
WST 3 為傳感器提供激勵電壓，并將模擬傳感器信號轉換為具有極高分辨率的數(shù)字測量信號。通過參數(shù)控制計算，它會產生內部測量值，這些值可以顯示在顯示屏上，并用于控制模擬輸出的電流或電壓信號。
包括用于監(jiān)控輸入信號或一些內部測量值的功能。監(jiān)控狀態(tài)可用于控制兩個輸出繼電器。
WST 3 可以作為從屬單元并入不同類型的網絡中?？梢酝ㄟ^ Profibus 和 Modbus 與控制單元/PLC 進行通信?；蛘?，Modbus 輸出可用于將測量值傳輸?shù)酵獠匡@示單元。
網絡可用于設置參數(shù)值，但也可以從儀器前面板進行設置。
WST 3 內置于緊湊型外殼中，可輕松安裝在 DIN 導軌或平面上。儀器輸入和輸出彼此電隔離。
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.
