Product Description
Digital conductivity/salinity sensor is a new generation of intelligent water quality monitoring sensor which research&developed by our factory .Using high performance CUP Chip to measure the conductivity and temperature .Support to check the data , debugging and maintenance by mobile APP or computer.It has the advantages of easy maintenance, high stability, excellent repeatability and multi-function, which can measure conductivity value in liquid exactly . It is widely used to online monitor the conductivity value in liquid in thermal power generation,chemical fertilizer,metallurgy,environmental protection , pharmacy , biochemistry, food and tap water .
Main Features
- Digital Conductivity /salinity sensor , 4-20mA or RS485 signal output directly
- High Accuracy , high stability , strong anti-jamming
- It can connect to the internet of things , PLC and other equipment which has Rs485/4-20mA signal interface to collect data and maintenance without instrument .It is convenient for users to integrate sensors into industrial control environment ,such as ,upper computer system and the internet of things .
- By using the mobile phone app, the sensor can be collected, debugged and maintained by the wireless network (such as WIFI/ GPRS) or wired network ( OTG line and 485 / USB module)
- The sensor can be set up by RS485 communication , slave address , baud rate,online calibration ,recoverable factory setting , 4-20ma output range(4-20mA is optional ), coeffcient of proportionality and incremental compensation
- Using three points calibration method
- Power off protection >10 years
