4. Overview
The CRS451/CRS456, Submersible Water-Level Recording Sensor, provides reliable, accurate
pressure/level measurements that are fully temperature compensated.
The 24 bit A/D has simultaneous 50/60 Hz rejection and automatic calibration for each
measurement. A number of additional advanced measurement techniques are employed to
harness the best possible performance available from today’s state of the art pressure sensor
technology. The CRS451/CRS456 reverts to a low power sleep state between measurements. A
series of measurements are performed yielding a temperature and pressure value. This
measurement cycle can be as fast as 1 second.
The design features a piezoresistive sensor housed in a 316L stainless steel (CRS451) or titanium
(CRS456) package to enhance reliability. The rugged construction makes the CRS451/CRS456
suitable for water level measurement in irrigation applications, water wells, lakes, streams, and
tanks. The titanium package of the CRS456 makes it ideal for salt water or other harsh
environments.
The CRS451/CRS456 has three nose cone options. The weighted nose cone makes the transducer
easier to submerge to depth. The NPT option allows the sensor to be mounted to a 1/4 inch
fitting. The nose cones can be exchanged at a later time.
Communicating with the CRS451/CRS456 requires a micro USB cable and HydroSci software
running on a computer with Windows XP or later. Configurable settings can be changed using
Campbell Scientific’s HydroSci software utility.
