CS450-L

Pressure Transducer

Over the years, we’ve offered submersible pressure transducers from various manufacturers for measuring pressure, depth, or level in hydrological applications. We are pleased to announce that we have designed and are now producing our own pressure transducers, the stainless-steel CS450 and the titanium CS455. We designed them with the goal of offering a high-quality instrument and providing shorter lead times for ordering and recalibration.

These new transducers measure pressure with a static accuracy within ±0.1% FS over a 0°C-to-60°C temperature range. They measure temperature with ±0.2°C accuracy. The CS450 outputs either a digital SDI-12 or RS-232 signal to indicate observed pressure/level.


Features

  • Output acceptable for recording devices with SDI-12 or RS-232 capability, including Campbell Scientific dataloggers
  • Static accuracy of ±0.1% FS over a 0-to-60°C temperature range
  • Quality construction ensures product reliability.
  • Rugged stainless-steel case protects piezoresistive sensor.
  • Fully temperature-compensated
  • 24-bit A/D
  • Simultaneous 50/60-Hz rejection
  • Low-power sleep state between measurements reduces power consumption.
