Ordering Information

Pressure Transducers

When ordering a CS450 or CS455, you must choose a range option

and an accuracy option (see below).

CS450-L

Pressure Transducer with Stainless Steel Case and user-

specified length. Enter length, in feet, after the -L.

CS455-L

Pressure Transducer with Titanium Case and user-

specified length. Enter length, in feet, after the -L.

Range Options for CS450 and CS455 (choose one)

-2

Pressure range of 0 to 2.9 psig (0 to 20 kPa) or

up to 6.7 feet of fresh water*.

-7

Pressure range of 0 to 7.25 psig (0 to 50 kPa) or

up to 16.7 feet of fresh water.

-14

Pressure range of 0 to14.5 psig (0 to 100 kPa) or

up to 33.4 feet of fresh water.

-29

Pressure range of 0 to 29 psig (0 to 200 kPa) or

up to 67.0 feet of fresh water.

-72

Pressure range of 0 to 72.5 psig (0 to 500 kPa) or

up to 167.0 feet of fresh water.

-145

Pressure range of 0 to 145 psig (0 to 1000 kPa) or

up to 334.5 feet of fresh water.

Accuracy Options for CS450 and CS455 (choose one)

-SA

Standard Accuracy. Provides ±0.1% FS over 0° to

60°C temperature range.

-HA

High Accuracy*. Provides ±0.05% FS over 0° to 60°C

temperature range. Includes a calibration certificate.

Optional Calibration Certificate (Standard Accuracy Only)

-CC

If specified, a calibration certificate that contains

calibration information specific to the individual

unit is shipped with a standard accuracy probe.

Common Accessories

25431

Split Mesh Cable Grip.

25366

Replacement Desiccant Tube.

25414

CS450 or CS455 Weighted Nose Cone that facilitates

stand-alone submersion.

A200

Sensor to PC Interface (for configuring sensor).

A150-L

Single Sensor Terminal Case, Vented with Desiccant. En-

ter cable length, in feet, after the -L. Must choose a cable

termination option (see below).

Cable Termination Options for A150 (choose one)

-PT

Cable terminates in stripped and tinned leads for

direct connection to a datalogger’s terminals.

-PW

Cable terminates in connector for attachment to a

prewired enclosure.

-CWS

Cable terminates in a connector for attachment to a

CWS900-series interface. Connection to a CWS900-

series interface allows this sensor to be used in a

wireless sensor network.
