CTD Water Level, Conductivity & Temperature Sensor - Submersible Probe
Industrial submersible CTD sensor designed for continuous monitoring of water level, electrical conductivity, and temperature in groundwater, boreholes, tanks, rivers, dams, wetlands, coastal environments, and industrial water systems. Featuring RS485 Modbus RTU communication, 316 stainless steel construction, and customizable depth and conductivity ranges for harsh environmental monitoring applications.
The CTD Water Level, Conductivity & Temperature Sensor is a rugged industrial-grade submersible monitoring probe designed for real-time measurement of:
- Water level (pressure depth)
- Electrical conductivity (EC)
- Water temperature
The sensor combines multiple monitoring functions into a single compact stainless steel probe, making it ideal for environmental monitoring, groundwater analysis, aquaculture, water treatment, bore monitoring, seawater applications, and industrial process systems.
Constructed from durable 316 stainless steel, the probe is designed for long-term immersion in harsh environments including:
- Groundwater bores
- Wells
- Rivers and creeks
- Dams and reservoirs
- Seawater and coastal monitoring
- Wastewater systems
- Aquaculture tanks
- Industrial process water systems
The sensor communicates using RS485 Modbus RTU, allowing integration with:
- PLC systems
- RTUs
- SCADA systems
- Data loggers
- IoT gateways
- Telemetry systems
- Industrial monitoring platforms
The pressure depth range is customizable up to 200 metres, while the conductivity range can also be customised depending on application requirements.
Its compact cylindrical design allows easy installation into narrow bores, pipes, tanks, and monitoring wells.
