chlorine dioxide sensor/เครื่องวัดคลอรีนไดออกไซด์

รายละเอียดสินค้า

The single channel controller DULCOMETER® D1C is a measuring and control device based on microprocessor technology that grants highest process safety with a comprehensive application spectrum. The controller is configurable and can thus individually be adjusted to your requirements. This is not only valid for its type of control but also for its construction type (wall mounting or panel mounting) and many more parameters. You select what you need for your regulation task and only pay for that. Advantages Universally implementable, as many measuring values controllable: beside pH, Redox, conductivity and Chlorine, also Dissolved Oxygen, Fluoride, Bromine, Chlorine Dioxide, Chlorite, Ozone, Hydrogen Peroxyde and Peracetic Acid. Ideal adjustment to process requirements thanks to various stages of extension Seamless integration into your process technology: variable installation possibilities for the sensors and large number of control possibilities for metering devices. Optimized process flows through special functions such as disturbance feedforward, pH compensation for Chlorine, base load dosing and many limit value functions. Safety: limit value monitoring with standardized dosing time restrictions. Easy and clear user guidance with text indicator on big graphic display in 16 languages. Large, easily readable graphic display for measuring values, correction values and information. Features Limit value control with standardized control variable shutoff Disturbance insensitive probe connection in dual wire technology 2 signal outputs 0/4 - 20 mA galvanically separated Various construction types for wall and panel mounting 1 digital input for 'break' and 'error' measuring water Disturbance signal processing as digital or analogue signal 2 timers as cleaning contact or for shock dosing Additive basic load dosing Bidirectional control Neutral zone control Temperature compensation for pH, conductivity and Chlorine Dioxide process measuring pH correction for Chlorine Adjustable access code Technical Data Measurand Value Accuracy 0,5 % of measuring range Correction variable Temperature over Pt 100 or transmitter 4...20 mA Correction range 0...100°C Disturbance signals Adder/multiplier Control characteristic P, PI, PD, PID Control Bidirectional control Dead zone control Additive basic load manually adjusted control variable for test purposes Control output 2 reed contacts (pulse rate output) 2 power relays (pulse length) or 1 output for servomotor with report function 2 analogue outputs (0/4...20 mA) Analogue output 2 analogue outputs (0/4...20 mA) galvanically separated, max. load 600 Ω (2nd output 400 Ω). Adjustable direction measurement, correction and control variable.
