Digitisation of standard process sensors in your water or wastewater treatment plant
The BlueConnect module enables the conversion of standard analogue sensors into the digital world. In addition to the simple connection of sensors to the BlueBox system via CAN bus, sensors can also be integrated directly into a PLC via Modbus. The
necessary protocol is freely available and all necessary settings can be configured via the associated free of charge PC software.
This means that Water and Wastewater Treatment Plants are no longer restricted to Vendor Proprietary Systems when integrating various Vendor Sensors to Instruments, PLC’s and other Control Systems.
For example, a standard pH or DO Sensor can be connected to a small BlueConnect Module and the Output signal sent via Modbus direct to the PLC or other Supervisory Control System.
Alternatively, the BlueConnect can send a CAN bus signal direct to a Royce GO BlueBox Analyser/ Controller which accepts up to 200 Inputs.
Currently available Sensor Inputs for BlueConnect are:
- Analogue pH with/without Temperature (LTH S410)
- Analogue ISE (NH4 or NO3)
- Analogue Redox / ORP (LTH S400)
- Galvanic Dissolved Oxygen (Royce G95A)
- Selective Turbidity (B&C TU8325)
- Selective MLSS (B&C TU8355)
- Selective EC (GO SYS)
Digitisation of analogue sensors:
The BlueConnect module effortlessly brings an analogue sensor into the digital world. Once the sensor has been connected, the converted data can be read out via Modbus RTU (RS485). The associated protocol is freely available, enabling a direct connection to a PLC or a Modbus master. If a sensor is used that must be calibrated at certain intervals, the BlueConnect
can be connected to a laptop and calibrated with the
associated free of charge PC software.
