4-20mA sensor measurement range information

The slope of the sensor will vary by 65% to 150% based on the normal slope, depending on factors such as different models or applications

Recommended method for selecting the applicable range of sensors:

The concentration of the solution to be tested x 1.5=the measurement range of the sensor

For example, the concentration of the solution to be tested is 1.6 ppm x 1.5=2.4

Recommend using sensors with a measurement range of 0-5ppm

precision

After calibration under full-scale repetitive conditions

(25 ° C, pH 7.2 drinking water)

At 0.4 mg/l<1%

Within the measurement range of 1.6 mg/l<1% -2 mg/l:

Measurement range of 20 mg/l: within 4 mg/l<1%

At 16 mg/l<3%

Slope drift

After calibration under repeated conditions

(25 ° C, pH 7.2 for drinking water) Approximately -1% per month

Operating Temperature

Measure water temperature: 0...+45 ° C

(No condensation in water)

Environmental temperature: 0...+55 ° C

Temperature compensation is automatically compensated through integrated temperature sensors, and sudden temperature changes must be avoided

Allow for high work pressure

Not equipped with a positioning ring: 0.5 bar without pressure shock or vibration

Equipped with a positioning ring: 3.0 bar without pressure shock or vibration

The flow rate in the FCL flow cup is about 15-30 l/h, with a relatively low flow rate dependence

(Please refer to the "Relationship between Flow Velocity and Slope" on the next page of the data table)

pH range

pH 4 – pH 9, Reduced pH dependence

(Please refer to the "Relationship between pH and Slope" on the next page of the data table)

Conductivity 10 µ S/cm -50 mS/cm (seawater)

Run time * * Approximately used 2 hours

Response time T90: approximately 0.2 minutes (reaching 90% of the measured value)

Zero point correction is not required

Slope calibration is being conducted on the measuring device and analyzed using the DPD-1 method

Electrolyte: Store in the original bottle away from light, and at least one can be stored in an environment of+5...+35 ° C

Year or until the indicated shelf life

Cap:+5...+40 ° C in original packaging

(Used film caps are not recommended for long-term storage)

maintain

Regularly check the control signal, it is recommended to do so once a week

The following depends on the water quality:

Membrane cap replacement cycle: one year

Electrolyte replacement cycle: one year.

The residual chlorine sensor is imported from Germany and does not require electrolyte for measurement. There are no strict requirements for flow rate, and automatic temperature compensation ensures accurate measurement. After leaving the factory, it can be used on-site without calibration and has good linear response within the low value range of 0-0.1mg/L.

The residual chlorine transmitter adopts a liquid crystal display meter, a Chinese English switching interface, 4-20mA analog output, multiple calibration and adjustment functions, high cost-effectiveness, strong practicality, and is equipped with a protective box.
