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.
