+GF+ SIGNET2850 電導率/ 電阻率傳感器變送電路，可用于各種結構的電極，具有*大的安裝靈活性。通用型可安裝在管道、墻或儲罐上。如采用任何Signet的電導率/電阻率傳感器，可以有單路或雙路（僅數字型）輸入。對浸入式傳感器安裝，螺紋接線盒型能夠使用這些相同的傳感器。它也可以采用一體化組合系統。在線的安裝結構，可以選擇在0.01，0.1，1.0，10.0 cm－1標準單元。2850實際應用的電導范圍：0.055－200,000μS或電阻率范圍：18.2MΩ－10KΩ。所有2850單元應用時，可選擇兩種輸出：數字（S3L）輸出或4-20mA輸出。數字（S3L）輸出型*多允許6個傳感器直接輸入Signet 8900多參數控制器。可用兩線制4-20mA輸出，對標準單元電極范圍，可用8個4-20mA輸出。 另外可由用戶在現場選擇，每個范圍是否反向。所有2850單元都可配置NEMA 4X/IP65的外殼，允許連接運行電纜的長度可達1000ft（305m）。 EasyCal的標準功能是，對簡單的現場校驗，可自動識別電導試驗溶液的值。根據USP的要求，可用校驗工具對傳感器變送電路進行**校驗。
GF+SIGNET 2850 變送器詳細英文介紹
2850 Conductivity-Resistivity Sensor Electronics and Integral System
The Signet 2850 Conductivity/Resistivity Sensor Electronics are available in various configurations for maximum installation flexibility. The universal mount version is for pipe, wall, or tank mounting and enables single or dual (digital output only) inputs using any standard Signet conductivity / resistivity sensor. The threaded j-box version can be used with these same Signet sensors for submersible sensor mounting. It is also available as a combined integral system configuration for in-line mounting and includes a conductivity electrode in a choice of 0.01, 0.1, 1.0, 10.0, or 20.0 cm-1 cell constants. The 2850 is ideal for applications with a conductivity range of 0.055 to 400,000 µS or a resistivity range of 100 MΩ to 10 kΩ. Each range can be inverted and are field selectable.
All 2850 units are available with a choice of two outputs, digital (S3L) or 4 to 20 mA. The digital (S3L) output version allows for up to six sensor inputs directly into the Signet 8900 Multi-Parameter Controller. The two-wire 4 to 20 mA output is available with eight 4 to 20 mA output ranges for each electrode cell constant.
All 2850 units are built with NEMA 4X/IP 65 enclosures which allow wiring connections with long cable runs of up to 305 m (1,000 ft). EasyCal is a standard feature that automatically recognises conductivity test solution values for simple field calibration. A calibration tool is available to validate of the sensor electronics according to USP requirements.
