IQ SENSOR NET
Flexible through digital technology – The IQ SENSOR NET from WTW
Digital modular multiparameter system
Systems for decentralized single measuring points
NEW
System 182 XT-4 – the perfect system for up to 4 sensors
Terminal/ controller T 2020 XT with USB interface
IQ-LabLink – the direct connection to the laboratory meter
IQ Systems
Single measuring stations or sensor network – an easy choice …
The planning begins with a basic decision between 2 systems
Single point measuring system			Sensor network
System 182 (1 to 4 sensors)			System 2020 XT (up to 20 sensors)
·         Decentralized system for 1 to 4 sensors with integrated terminal. ·         Models with integrated analog or digital outputs (i.e. RS-485)/ field bus connections PROFIBUS or MODBUS) available ·         All IQ sensors can be connected			·        Central (network) and decentralized system for up to 20 sensors possible – extendable by up to 3 terminal/ controller units for flexible installation within the network. ·        Digital and/ or analog outputs, can be combinated and extended by modules and integrated within the network.
Digital IQ sensors stand for:
·           Long distance from sensors to measuring system
·           Fail-save transfer of signals
·           Calibration data can be stored in the sensor
·           Standardized plug connection directly at the sensor
·           Calibration can be processed in the laboratory
System 182
·           Up to 4 sensors can be connected out of a variety of 19 available digital sensors
·           pH, ORP, DO, conductivity, temperature and turbidity/ suspended solids, nutrient parameters ammonium, nitrate and COD can therefore be measured directly, in-situ
·           Power supply through wide range mains converter (100-240 VAC) or 24 V alternative
·           Digital outputs PROFIBUS DP or MODBUS RTU
·           Analog model with up to 5 analog outputs and 6 relays
