CS451/CS456 Submersible Pressure
Transducer

1. Introduction

The CS451/CS456 Submersible Pressure Transducer provides pressure and
temperature measurements. It uses the SDI-12 or RS-232 communications
protocols to communicate with an SDI-12 or RS-232 recorder simplifying
installation and programming. The CS450/CS455 can be used with an A150
desiccated case allowing the transducer to be connected to a CWS900 wireless
sensor or prewired enclosure.

2. Cautionary Statements

• READ AND UNDERSTAND the Precautions section at the front of this

manual.

• Sensor will be damaged if it is encased in frozen liquid.

• Although the CS451/CS456 is rugged, it is also a highly precise scientific

instrument and should be handled as such. There are no user-serviceable
parts and any attempt to disassemble the device will void the warranty.

• Dropping the instrument or allowing it to “free fall” down a well may

damage the transducer.

• Never suspend the CS451/CS456 from the connections at the top end of

the cable. Sharp bends or excessive pinching of the cable can cause
damage and may pinch off the vent tube causing measurement errors.

• Confirm the compatibility of the sensor and cable to non-water

environments before installation.

• The CS456 instead of the CS451 should be used in harsh water

applications, including salt water.

3. Initial Inspection

• Upon receipt of the CS451/CS456, inspect the packaging for any signs of

shipping damage and, if found, report the damage to the carrier in
accordance with policy. The contents of the package should also be
inspected and a claim filed if any shipping related damage is discovered.

• The model number and pressure range is etched on the housing and the

cable length is printed on the label near the connection end of the cable.
Check this information against the shipping documentation to ensure that
the expected product was received.

• Ensure that the desiccant tube is attached to the vent tube on the cable.

The desiccant should be blue; replace if it is another color.

4. Quickstart

Short Cut is an easy way to program your datalogger to measure the sensor and
assign datalogger wiring terminals. The following procedure shows using
Short Cut to program the CS451/CS456.

1. Install Short Cut by clicking on the install file icon. Get the install file

from either www.campbellsci.com, the ResourceDVD, or find it in
installations of LoggerNet, PC200W, PC400, or RTDAQ software.

2. The Short Cut installation should place a Short Cut icon on the desktop of

your computer. To open Short Cut, click on this icon.

3. When Short Cut opens, select New Program.

8. Select any other sensors you have, then finish the remaining Short Cut

steps to complete the program. The remaining steps are outlined in Short

Cut Help, which is accessed by clicking on Help | Contents |
Programming Steps.

9. If LoggerNet, PC400, or PC200W is running on your PC, and the PC to

datalogger connection is active, you can click Finish in Short Cut and you
will be prompted to send the program just created to the datalogger.

10. If the sensor is connected to the datalogger, as shown in the wiring

diagram in step 6, check the output of the sensor in the datalogger support
software data display to make sure it is making reasonable measurements.

The CS451/CS456 pressure transducer provides a reliable, accurate
pressure/level measurement that is fully temperature compensated. Its 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 transducer technology. The transducer reverts to a low power sleep
state between measurements. A series of measurements are performed yielding
a temperature and pressure value. This measurement cycle takes less than 1.5
second. The transducer can also be configured to output pressure only in less
than 1 second. The measurement cycle is activated using SDI-12 or RS-232
commands.

The transducer consists of a piezoresistive sensor housed in a 316L stainless­steel (CS451) or titanium (CS456) package to enhance reliability. The rugged
construction makes the CS451/CS456 suitable for water level measurement in
irrigation applications, water wells, lakes, streams, and tanks. The titanium
package of the CS456 makes it ideal for salt water or other harsh environments.
The cable incorporates a vent tube to compensate for atmospheric pressure
fluctuations and the jacket is made of rugged Hytrel®, designed to remain
flexible and tough, even under harsh environmental conditions.

The CS451/CS456 has two communication options: SDI-12 or RS-232. The
CS451/CS456 is shipped from the factory with both communications options
enabled; there is no configuration required. As an SDI-12 sensor, the
CS451/CS456 is shipped with an address of 0.

Two values are output by the CS451/CS456 — pressure/level and temperature.
The CS451/CS456 is shipped from the factory to output pressure in psig and
temperature in degrees Celsius.

The CS451/CS456 has three nose cone options. FIGURE 5-1 shows the nose
cone options. The weighted nose cone makes the transducer easier to
submerge to depth. The 1/4 inch NPT nose cone allows the transducer to be
used in closed-pipe applications. Nose cones can be switched out later.

The –L in the transducer’s model name indicates user-specified cable length.
