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.
This manual provides information only for CRBasic dataloggers.
It is also compatible with most of our retired Edlog dataloggers.
For Edlog datalogger support, see an older manual at
www.campbellsci.com/old-manuals or contact a Campbell
Scientific application engineer for assistance.
2. Cautionary Statements
x READ AND UNDERSTAND the Precautions section at the front of this
manual.
x Sensor will be damaged if it is encased in frozen liquid.
x 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.
x Dropping the instrument or allowing it to “free fall” down a well may
damage the transducer.
x 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.
x Confirm the compatibility of the sensor and cable to non-water
environments before installation.
x The CS456 instead of the CS451 should be used in harsh water
applications, including salt water.
3. Initial Inspection
x 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.
