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 -L in the transducer’s model name
indicates user-specified cable length.
Before using the CS451/CS456 please study
•Section 2, Cautionary Statements
•Section 3, Initial Inspection
•Section 4, Quickstart
2. Cautionary Statements
•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.
•Care should be taken when opening the package not to damage or cut the
cable jacket.
•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 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.

CS451/CS456 Submersible Pressure Transducer
•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.
•The transducer comes with a desiccant tube attached to the cable.
4. Quickstart
This quickstart guide assumes:
•Default settings used (SDI-12 address 0, pressure reported in psig,
temperature reported in C)
•ShortCut Program Generator for Windows (SCWin) used to program
datalogger, calculate offset, and generate wiring diagram
For complete configuration, installation, wiring, and programming information,
see Section 7, Operation.
4.1 Step 1 — Desiccant Check
The desiccant tube is shipped with a black cap to cover the
vent hole. This cap MUST be removed prior to installation.
CAUTION
Ensure the desiccant is blue; replace if not.
The desiccant tube must always be attached to the CS451/CS456.
4.2 Step 2 — Choose Appropriate Depth
The CS451/CS456 must be installed below the water at a fixed depth. This
depth should be chosen so the water pressure will never exceed the
transducer’s pressure range (twice its pressure range).
The output reading will not be correct, and the transducer
can be damaged if pressure is excessive (2 x full scale).
CAUTION
Pressure can be converted to feet of fresh water using the following simple
equation:
1 psi = 2.31 feet of water
For example, the maximum depth with a pressure range of 0 to 7.25 psig is
16.748 feet of water.

CS451/CS456 Submersible Pressure Transducer
4.3 Step 3 — Dislodge Bubbles
While submersing the transducer, air bubbles may become trapped between the
pressure plate and the water surface, causing small offset errors until the
bubbles dissolve. Dislodge these bubbles by gently shaking the CS451/CS456
while under water.
If bubbles are not removed by rotation and shaking
underwater (or bleeding out the air in a closed system), the
CS451/CS456 reading will drift lower by the distance of the
gap as the bubbles are slowly dissolved into the water over
time.
CAUTION
Hitting against the well casing or other solid surface could
damage the transducer.
CAUTION
4.4 Step 4 — Install Transducer
Lower the transducer to an appropriate depth.
Do not drop the instrument or allow it to “free fall” down a
well as this may damage the sensor.
CAUTION
With long drops it may be necessary to use the weighted nose cone (option
-WN).
The transducer body can be strapped with tie wraps or tape. Campbell
Scientific offers cable ties (pn 7421) that can be used to secure and strain relief
the cable. If installing in a well, fasten the cable to the well head. Wrap the
cable ties around the cable jacket.
Never suspend the CS451/CS456 from the connections at
the top of the cable. Sharp bends or excessive pinching of
the cable can cause damage and may pinch off the vent
tube causing measurement errors.
CAUTION
Several readings should be taken to ensure proper operations after installation.
4.5 Step 5 — Measure Initial Water Elevation
Use a staff gauge (or other device) to measure the initial elevation of water.
This value is used to calculate an offset that corrects the final measurement for
errors due to zero offset or installation. SCWin will make the offset
calculation. Refer to Section 7.2.2, Offset Calculation, if not using SCWin to
calculate the offset.

4.6 Step 6 — Use SCWin to Program Datalogger and Generate
Wiring Diagram
The simplest method for programming the datalogger to measure a
CS451/CS456 is to use SCWin.
1. Open Short Cut and click on New Program then select Next.
2. Select a datalogger and scan interval then select Next.
