FIGURE 1-1. A547 Interface and CS547A Conductivity and Temperature Probe
2. Specifications
2.1 CS547A Probe
Construction The probe housing is epoxy
Size — L x W x H 89 mm (3.5 in.) x 25.4 mm (1 in.) x 19 mm (0.75 in.)
Minimum Pipe ID in
which CS547A Fits
28 mm (1.1 in.)
Maximum Cable Length 305 m (1000 ft). The sensor must be ordered with desired
length as cable cannot be added to existing probes.
Depth Rating Maximum 305 m (1000 ft)
pH Range Solution pH of less than 3.0 or greater than 9.0 may
damage the stainless steel housing.
Electrodes Passivated 316 SS with DC isolation capacitors.
Cell Constant Individually calibrated. The cell constant (K
c
) is found
on a label near the termination of the cable.
Temp. Range of Use 0 ° to 50°C.
EC Range Approx. 0.005 to 7.0 mS cm -1 .
