Description

Small size and a choice of sensor lengths down to just 25mm make the sensor suitable for a variety of applications, and the optional pressure or temperature sensor adds versatility. There is a choice of data formats to allow interface to existing systems. We will also consider OEM and custom designs.

Technical information

Sound Velocity Measurement
Each sound velocity measurement is made using a single pulse of sound travelling over a known distance, so is independent of the inherent calculation errors present in all CTDs.

Our unique digital signal processing technique virtually eliminates signal noise, andgives almost instantaneous response; the digital measurement is also entirely linear, giving predictable performance under allconditions.
