What scenes are fluorescent dissolved oxygen sensors used in

1. Product Overview

The water quality fluorescent dissolved oxygen sensor is a continuous monitoring instrument probe widely used in dissolved oxygen, saturation, oxygen partial pressure and temperature in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food and tap water.

Dissolved oxygen detector adopts fluorescence method, the sensor product has a long life, no maintenance, excellent performance, continuous monitoring data is transmitted and output connected to the recorder to realize remote monitoring and recording, and it can also be connected to the RS485 interface through the MODBUS-RTU protocol, which can be easily connected The computer realizes the monitoring and recording.

The dissolved oxygen sensor is matched with a waterproof housing to convert the signal of the aqueous solution into a standard 485 signal after digital setting and analysis. The product does not need to be calibrated at one time, and it can be used by hand.

2. Features

The probe of the aqueous fluorescence method detector is a fluorescence method probe, which uses the principle of fluorescence quenching for measurement. The fluorescence method is relatively active in recent years and can overcome the shortcomings of traditional classical measurement methods that cannot be continuously measured online. The fluorescence method does not consume oxygen and is not affected by magnetic fields. , It does not consume probes, has high sensitivity, low detection limit, and long life. It has been widely used in sustainable online monitoring and other advantages.

3. Interface description

The power interface can be a wide voltage power input of 12-24V. The product pays attention to the positive and negative of the signal line, and do not reverse the positive and negative of the signal line.

Precautions:

Please be careful not to connect the wrong wiring sequence. Incorrect wiring will cause the equipment to fail to operate normally or to burn the equipment.

The sensor should avoid contact with organic solvents, alcohol, paint, oil and high-concentration gases, including silica gel and other adhesives.

The factory default provides 4.8 meters long wire, customers can extend the wire as needed or wire in order.

There is no yellow line in the line sequence that may be provided in some factory batches. At this time, the gray line is equivalent to replace the yellow line.
