HLS CT310 RS Integrated Water Monitoring Features
Three Measurements In One Submersible Probe
The HLS CT310 RS brings together level, conductivity and temperature measurement in one transmitter, helping to simplify installation in boreholes, pools and wells.Digital RS 485 Communication
The transmitter communicates via RS 485 using Modbus RTU or HART protocols. It can handle both protocols simultaneously for flexible connection to compatible monitoring systems.Automatic Conductivity Range Selection
Automatic switching across the 5 to 100 µS, 100 µS to 1 mS and 1 mS to 200 mS conductivity ranges enables measurement over a wide conductivity span.Temperature Compensated Measurement Values
The level and conductivity channels are digitally temperature compensated. Modbus input registers provide both the measured conductivity and the conductivity value recalculated to the 25°C reference temperature.Accurate Hydrostatic Level Measurement
The level channel achieves accuracy of 0.1% of span and provides a 200 ms response time for continuous water level monitoring.Integrated Pt1000 Temperature Sensor
The Pt1000 sensor measures temperature from 0°C to 70°C, with stated accuracy of ±2°C in the compensated range.Corrosion Resistant Wetted Materials
The housing and diaphragm are stainless steel 1.4435, equivalent to 316L. The conductivity sensor uses platinum on 96% alumina ceramic and the standard seal is FKM.Submersible Construction With Cable Options
IP68 protection and a cable with integrated air tube for atmospheric pressure reference support submerged installation. PVC, PUR and FEP cable sheath options are available.
HLS CT310 RS Applications For Water Quality And Level Monitoring
