Water quality conductivity sensor

1.Water quality conductivity sensor application environment description

Water quality conductivity sensor monitors changes in water quality by measuring the electrical conductivity of water and is used to assess the total amount of dissolved ions in water.Used for environmental water quality testing, various high/low ionic strength water sample testing, and can meet the requirements of most industrial/environmental applications for online conductivity measurement.

Signal output: RS485 (MODBUS-RTU).

Internal signal isolation technology, strong anti-interference.

Good reproducibility, thermal stability, low drift, small size, fast response

Easy and simple installation, 3/4NPT pipe thread, convenient for submerged installation or installation in pipes and tanks

Stable performance and long service life

IP68 waterproof standard

24*1.2,18*1.5*2,28*2,2

2. Water quality conductivity sensor technical performance and specifications

1. Technical parameters

2. Water quality conductivity sensor dimensions

The sensor connector is an M12 aviation plug connector with 5 pins.

3. Water quality conductivity sensor installation and electrical connection

1. Installation

Note: The sensor cannot be installed upside down or horizontally, but must be installed at an angle of at least 15 degrees.

2. Electrical installation

The cable is a 5-core shielded cable, line sequence definition: Brown - power line (12~24VDC)

Black - Ground (GND)

Blue-485A Green-485B

Yellow - 4-20mA current output (can be left floating if not used)

The wiring sequence should be carefully checked before powering on to avoid unnecessary losses due to wiring errors.

4. Water quality conductivity sensor maintenance and care

1. Use and maintenance

Conventional electrodes need to be cleaned and calibrated periodically. The maintenance cycle is determined by the customer based on their working conditions. Conventional electrode cleaning method: Use a soft brush to remove attachments (be careful to avoid scratching the electrode surface), then clean with distilled water, and then perform calibration operations.
