型號描述
Bürkert 8222 型設備是一個用于測量液體電導率的緊湊型傳送器。傳送器 8222 裝配有一個傳感器。該傳感器被一個銷釘固定在外殼上，不可拆卸。含有電子設備模塊及可拆卸指示器的外殼，裝配有一個蓋子。傳感器本身具有三個不同的單元常數 C，由一個溫度探測器 Pt1000 和兩個電導率電極構成。在常數 C 為 0.01 或 0.1 時，傳感器由不銹鋼構成，而在常數 C 為 1.0 時，由石墨構成。利用一個鎖緊螺母將單元固定在工序中。僅在調試、配置和校準時或者作為工藝值指示器使用時，才需要可選指示器。8222 型設備是可用的：- 帶有三個可編程的輸出端：兩個晶體管輸出端和一個雙線 4-20 mA 電流輸出端 - 帶有四個可編程的輸出端：兩個晶體管輸出端和兩個三線 4-20 mA 電流輸出端。型號 8222 能夠轉換測量信號，以不同測量單位顯示不同數值（如果已插接指示器）并計算通過一個或兩個 M12 插拔連接器傳輸的輸出信號。
1）模擬的 4-20 mA 輸出端
2）帶有鎖緊螺母的通用過程接口
3）三種不同的電導率傳感器，適合較寬的測量范圍
4）溫度補償測量
Type Description
The Bürkert Type 8222 is a compact device designed for measuring the conductivity of fluids. The transmitter consists of a sensor, pluggedin and pined to an enclosure with cover, containing the the electronic module and a removable display. The sensor comprises a cell with two electrodes and a Pt1000 temperature probe. The sensor itself is available with three different cell constants C, these with C=0.01 or 0.1 are fitted with stainless steel electrodes and those with C=1.0 are fitted with graphite electrodes.The conductivity transmitter can operate independant of the display but it will be required for programming the transmitter (i.e. selection of sensor cell constant, language, measuring range, engineering units, calibration...) and also for visualizing continuously the measured and processed data. The device Type 8222 is available: - with three fully programmable outputs: two transistor and one 2-wire 4-20 mA current outputs - with four fully programmable outputs: two transistor and two 3-wire 4-20 mA current outputs.The electronics of Type 8222 converts the measured signal, displays different values in different physical units (if display mounted) and computes the output signals, which are provided via one or two M12 fixed connectors.
1）Analog 4-20 mA output
2）Universal process connection
3）Three cell constants for covering a wide measuring range
4）Temperature compensated measurement
