描述 Description

The Campbell Scientific CS547A probe with the A547 Interface measures the electrical conductivity (EC) and temperature of water. EC is measured by three passivated cylindrical electrodes isolated from DC with capacitors. Temperature sensed with a thermistor.

The CS547A is easy to clean and resistant to corrosion. It has rounded ends to facilitate installation and removal.

Dissolved solids can be estimated from conductivity measurements using empirical conversion factors. For ground water applications, an optional weight and a split mesh cable grip are recommended for cables over 30m.

For correct operation there must be a flow of water through the sensor body.

The A547 Interface contains the required completion resistors and blocking capacitors – the probe can be used with a AM16/32B multiplexer and one A547.
