This product is no longer available and has been replaced by: CS456,CS451. Some accessories, replacement parts, or services may still be available.


The CS445 was a submersible pressure transducer that output a digital SDI-12 signal to indicate observed pressure level; the SDI-12 signal was measured and recorded by the datalogger. The static accuracy was ±0.1% over a 0° to 50°C temperature range.

The "-L" on a product model indicates that the cable length is specified at the time of order.



  • Excitation: 8 to 24 Vdc
  • Static Accuracy: 0.1% span BFSL
  • Operating Temperature: 0° to 60°C, nonfreezing
  • Diameter: 1.0" (2.5 cm)
  • Length: 13" (33.0 cm)
  • Cable Diameter: 0.29" (0.74 cm)
