Camur Corrosion Monitoring

The Camur system works differently. It consists of small electronic units called "nodes" - one "node" is placed near every sensor. The node contains an A/D converter, a microprocessor, galvanic separation between analogue and digital side and analogue circuitry to perform advanced measurements like LPR (Linear Polarization Resistance).

The node may even be embedded in concrete alongside the sensor if so required. To collect the data, only one single bus cable is needed. This bus cable runs by every node and ends at the Camur Controller. The Controller takes care of storage of data, as well as communication with all the nodes and with the remote cloud service.

Features

Important advantages with the Camur II system:

• Digital signal transfer, protects integrity of measured signal, immune to electromagnetic noise
• Signal transferred digitally on a bus, drastically reduce amount of cables
• Galvanic separation between analogue and digital side of nodes, eliminates risk of errors due to accidental, unintentional connections between sensors
• "Plug and play" functionality, every sensor gets ID and intelligence through it's node
• Advanced measurements - every sensor has it's own microprocessor
• The Camur II system is suitable for both small and large systems, you can always scale the system to fit your requirements exactly.

Operations with Force ERE 20 Electrodes

ERE 20 electrodes are long life manganese dioxide reference electrodes that can be used to monitor reinforcing steel corrosion state and also to control cathodic protection systems.

When interfaced with a Camur II system the system can either continuously measure potentials to provide corrosion information or can perform scheduled potential decay measurements which will indicate the proper operation of potential measurement.

Operation with Force Corrowatch/Corrorisk Sensors

Ladder probes are used to monitor the progress of chloride or carbonation corrosion fronts through the concrete cover of structures. CorroWatch sensors are cast in to new structure and CorroRisk sensors are retrofit able to existing structures.

CorroRisk sensors are retrofit able to existing structures. “Corrowatch Nodes” are modules to connect to Force’s ladder probes, each node periodically monitors temperature and corrosion rate using linear polarisation resistance.

Sample System

A complete Camur system will consist of at least:

• One Camur Controller with power supply
• One Camur Bus Interface interface with power supply for the bus
• USB A-B cable for connecting the Camur Controller with the above interface
• One (probably several or many) Camur nodes (P, LPR, HUM, CW)
• Camur bus cable

In many cases you may also need:

• WLink nodes to replace bus cable with wireless links in some areas
• One modem, GSM module or internet connection
• One control cabinet for the Camur II Controller, modem, power supply etc.
