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.
