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 is 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 CS547A Standard probe; please specify cable length.* A547 Interface containing completion resistors for use with the CS547. A weight and split mesh strain relief sleeve are available as options. *In all cases, please specify the cable length required in metres (maximum 300).

Applications
W Calculation of stream discharge rate Water quality monitoring Tracking of water-borne pollutants in aquifers CS547A Probe CSL 424 W W blocking capacitors – the probe can be used with a AM16/32B multiplexer and one A547. Compatibility The output of the CS547A can be measured by all current Campbell Scientific dataloggers (except the CR200 series). The conductivity and temperature measurements require a differential and single-ended input, respectively. Two separate excitation channels are also needed. A547 Interface
We reserve the right to alter specifications without notice Specifications Probe Construction: The sensor consists of three stainless steel rings mounted in an epoxy tube. Size: (L x W x H) 89mm x 25.4mm x 19mm Weight: 120g (with approx. 1 metre cable) Maximum Cable Length: 300m. It is recommended that the sensor is ordered with the desired length to avoid any jointing problem s; for ground water applications it is also recommended that an optional (80g) weight and cable grip are ordered for cable lengths over 30m. Depth Rating: Maximum 300m. pH Range: Solution pH of less than 3.0 or greater than 9.0 may damage the housing. Cleaning: Nylon brush provided Conductivity Sensor Electrodes: Passivated 316 stainless steel with DC isolation capacitors. Cell Constant: Individually calibrated. The cell constant (K c) is given on a label near the termination of the cable. Operating Temperature Range: 0°C to +50°C Conductivity Range: Approx. 0.005 to 7.5mScm -1 Accuracy:* In KCl and Na2SO4, NaHCO3, and NaCl standards at 25°C ±5% of reading, 0.45 to 7.0mScm-1 ±10% of reading, 0.005 to 0.44mScm-1 * User calibration of individual probes may improve the quoted accuracy. Temperature Sensor Thermistor: Betatherm 100K6A1 Range: 0°C to +50°C Accuracy: ±0.4°C (worst case) A547 Interface: Size: 63.5 x 22.2 x 44.5mm Weight: 170g Temperature Range: -15°C to +50°C Multiple sensors can be measured by connecting the probes to an AM16/32B multiplexer and then connecting the multiplexer to a single A547 interface
