产品详情

Universal monitor DIQ/S 281. The new system 281 – the digital and cost-efficient single parameter measuring point with proven IQ Sensor Net technology and IQ sensors for the standard parameters. Low-cost alternative to analog measuring points

The System 281 combines the known performance of analog products with the advantages of the digital IQ Sensor Net:

Proven and reliable IQ Sensor Net technology
100 % IQ Sensor Net look & feel
Versions with analog outputs, Modbus RTU and HART available
2 relays for alarm for main and secondary value
You can easily upgrade to DIQ/S 282/284, since IQ sensors can be retained
Free software updates with new features
Stable, robust and proven measuring technology

Measurement Parameters:

Matching digital IQ sensors for pH/ORP, conductivity, D.O., turbidity, suspended solids and sludge level (also as seawater version for corrosive media)

Models:

DIQ/S 281-CR2 with power supply via a wide range power supply unit (100-240VAC), 2 analog outputs (0/4-20 mA) and 2 relays
DIQ/S 281-CR2/24V with 24V power supply, 2 analog outputs (0/4-20 mA) and 2 relays
DIQ/S 281-MOD with a wide-range power supply unit (100-240VAC), MODBUS interface (RS 485) and 2 relays
DIQ/S 281-HART with a wide-range power supply unit (100-240VAC) and 2 relays

Made for many applications:

Once developed for wastewater the IQ Sensor Net is also successfully applied in drinking water applications and the process industry for many years. Try it yourself! Some examples:

With SensoLyt® 700 IQ for different pH ranges in drinking water
With VisoTurb^® 700 IQ, the turbidity sensor with ultrasonic cleaning in the wwtp outlet
With the calibration free dissolved oxygen sensor FDO® 700 IQ in the aeration basin
With TetraCon^® 700 IQ, the 4 electrode conductivity cell in the process industry
With the suspended solids sensor ViSolid^® 700 IQ with ultrasonic cleaning in the aeration basin of a wwtp with industrial wastewater
With IFL 700 IQ, the ultrasonic sensor for detailed presentation of sludge profile in the post-sedimentation
