CS451/CS456 Submersible Pressure Transducer
7.4.2.1 Example Program for CR10(X) Dataloggers
Below is a portion of a CR10X program that measures the CS451/CS456.
The instructions below do not store data in final storage.
Instruction 92, Instruction 77 and processing instructions such as
Instruction 70 are required to store the data permanently.

After Instruction 105 is executed, the input location called “Data_1” will hold
the measured pressure, reported in PSI, and the input location called Data_2
will hold the measured temperature, in degrees Celsius. The results can be
further processed by the datalogger. Note that Port 1 specifies that the SDI-12
data line is to be connected to the Port C1.
8. Maintenance
Campbell Scientific recommends that the CS451/CS456 be factory recalibrated
and checked every 24 months. Before a CS451/CS456 sensor is sent to
Campbell Scientific, the customer must get an RMA (returned material
authorization) number, and fill out the Declaration of Hazardous Material and
Decontamination form.
The CS451/CS456 has no user-serviceable parts. Cable can be damaged by
abrasion, rodents, sharp objects, twisting, crimping or crushing, and pulling.
Take care during installation and use to avoid cable damage. If a section of
cable is damaged, it is recommended that you send your sensor back to replace
the bale harness assembly.
Periodic evaluation of the desiccant is vital for keeping the vent tube dry. The
CS451/CS456 ships with the desiccant tube attached. To assess the
effectiveness of the desiccant, use one of the following:
