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 CS455 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 titanium 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.
