Campbell Scientific CS451 & CS456 Pressure Transducers

Rugged, accurate pressure transducers for measuring water level. SDI-12 or RS232 output.

Campbell Scientific's Submersible Pressure Transducers provide reliable, accurate pressure/level measurements that are fully temperature compensated. The CS451 & CS5456 replace the CS450 & CS455

Output is either SDI-12 or RS-232 to be compatible with a range of measuring devices including Campbell Scientific dataloggers.

The cable is rugged Hytrel cable that remains flexible, even under harsh environmental conditions. The cable incorporates a vent tube to compensate for atmospheric pressure fluctuations. To prevent water vapor from entering the inner cavity of the transducer, the vent tube opening should terminate inside a desiccated enclosure or a desiccant tube.

The static accuracy is ±0.1% FS over a 0° to 60°C temperature range.

A high accuracy ±0.05% variant is also now available as an option.

The CS456 has a titanium body, while the CS451 is made from stainless steel.

Measurement ranges available are:

  • 0 to 2.9 psig (0 to 20 kPa)
  • 0 to 7.25 psig (0 to 50 kPa)
  • 0 to14.5 psig (0 to 100 kPa)
  • 0 to 29 psig (0 to 200 kPa)
  • 0 to 72.5 psig (0 to 500 kPa)
  • 0 to 145 psig (0 to 1000 kPa)
