5.1 Installs
Note: At least 2 cm away from the bottom and side walls of the
container during installation and testing.
5.2 Electrical connection
The cable is a 4-core twisted pair shielded wire defined in line
sequence:
Red wire -- power cord (12V-24VDC)
Black line (GND)
Blue Line -- 485a
White line -- 485b
Before electrification, the wiring sequence should be carefully
checked to avoid unnecessary losses caused by wiring errors.
Wiring instructions: Consider the cable long-term immersion in
water (including seawater) or exposed to air, all wiring is
required to do waterproof treatment, customer cable should have a
certain anti-corrosion ability.
6.1 Use and Maintenance
The regular electrode needs to be cleaned and calibrated
periodically, and the maintenance cycle is decided by the customer
according to his own working condition. Conventional electrode
cleaning method: with a soft brush to remove the attachment (care
to avoid scratching the electrode surface) , and then clean with
distilled water, after the calibration operation.
Cleaning method of inductive electrode:
Inductive electrode is basically maintenance-free; the shell of
pollution or mild scaling does not affect its normal work.
If cleaning, with a soft brush or sandpaper to remove the
attachment, and then use distilled water cleaning, after the
calibration operation.
Because inductance type electrode often works in easy to scale up
or dirty environment, cleaning can be appropriate to increase the
force. A minor scratch on the electrode surface does not affect the
normal operation of the electrode, but to avoid penetrating the
electrode shell.
6.2 Calibration
a) Zero Calibration
Rinse the sensor with distilled water and drain the liquid with
filter paper. The sensor is connected to the power supply and
placed vertically in the air for about 3 minutes. After the
numerical value is stable, zero calibration is carried out. The
calibration instructions are detailed in the appendix.
b) slope calibration
Place the electrode vertically in the standard solution (20% full
range) and note that the slope of the electrode is calibrated at
least 2 cm from the bottom and side walls of the container. The
calibration instructions are detailed in the appendix.
