Installation Instructions
No output or output error
possible reason:
1) The range corresponding error causes the PLC to calculate an error.
2) The wiring method is incorrect or the wiring sequence is wrong.
3) The power supply voltage is incorrect (24V power supply for 0~10V models).
4) The distance between the transmitter and the collector is too long, causing signal disturbance.
5) The PLC collection port is damaged.
6) Equipment damage.
Notes
1) The aging test before use is not less than 48 hours;
2) Electrolyte leakage will cause injury, please do not disassemble the sensor at will;
3) The sensor should avoid contact with organic solvents, paints, chemicals, oils and high-concentration gases;
4) The sensor should not be immersed in an oxygen-free environment for a long time,
otherwise it will damage the performance of the sensor;
5) It should not be used for a long time in an environment containing corrosive gases,
corrosive gases will damage the sensor;
6) It is forbidden to store and use in high concentration alkaline gas for a long time;
7) The air inlet holes must not be blocked or contaminated.

o3 gas sensor is widely used in water disinfection, food processing and purification, food storage and preservation, medical and health, and household disinfection and purification.
In ozone applications, a certain concentration of ozone is an important parameter to ensure disinfection, energy conservation and pollution prevention.
But as If the concentration of ozone in the environment is too high, it will cause harm to the human body. Therefore, it is very necessary to effectively monitor the concentration of ozone.
The transmitter uses electrochemical technology to measure O3 concentration, and the reaction is quick and sensitive, which can reliably detect ozone concentration.
