CS450-L Pressure Transducer

Other Accessories

The 25414 nose cone adds 0.465 lbs (0.211 kg) of weight to the CS450. Additional weight makes the transducer easier to submerge to depth.
The 25431 Split Mesh Cable Grip is recommended for use in wells to center the cable and to provide a method of suspending the cable, reducing cable stretch.
The transducer's cable incorporates a vent tube that terminates inside of the 25366 desiccant tube. The 25366 is offered as a common accessory for customers who want a spare desiccant tube.
The A200 interfaces a CS450 with a PC, allowing sensor settings to be changed via our Device Configuration Utility (DevConfig).
A150-L Single Sensor Terminal Case, Vented w/Desiccant
The A150 desiccated case is a small, self-contained junction box that allows the CS450 to be connected to a PWENC connector or a CWS900 wireless sensor connector.
A150-L Options - show details
-L ft per cable

Allowed values: 0-1000 ft, increments of 1 ft

Cable Termination Options - show details
-PT -PT w/Tinned Wires
With the -PT option, the cable terminates in pigtails that connect directly to the datalogger.
-PW -PW w/Pre-Wire Connector
With the -PW option, the cable terminates in a connector that attaches to a prewired enclosure.
-CWS -CWS w/CWS900 Connector
With the -CWS option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.

Replacement Parts

The 25366 may be purchased to replace a damaged desiccant tube. The CS450 is shipped with this small desiccant tube attached to it. The transducer's cable includes a vent tube that terminates inside of the 25366. The desiccant tube prevents water vapor from entering the inner cavity of the transducer.
The 29137 is replacement desiccant for this transducer's desiccant tube. It provides enough desiccant to fill ten desiccant tubes.


The 25425 requires an RMA (Returned Material Authorization) from Campbell Scientific. When it is ordered, we will recalibrate the CS450 to meet original specifications. Before and after calibration sheets are supplied with the pressure transducer.
The 25479 is the calibration certificate for the CS450 Pressure Transducer. Although every CS450 is calibrated, a calibration certificate is not automatically shipped with the sensor. When a customer orders a calibration certificate, the customer will get a calibration certificate that contains calibration information specific to the individual unit.
