The "Typically Ships Within" value is an estimate of the number of calendar days within which this product is ready to ship from Campbell Scientific. Orders with more than 10 built-to-order products will likely increase the time needed to prepare the order for shipping.

To estimate how long it will take to receive an order that contains multiple products, combine the longest Ships Within value with the transit time of the shipping method you select.

Some specialized products have long Ships Within values. Because of this, you might consider submitting a separate order for these products so your other products won't be delayed.

Common Accessories

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 CS451V with a PC, allowing sensor settings to be changed via our Device Configuration Utility (DevConfig).
The 31648 is a clamp with 1 in. NPT threads that allows the CRS451V to be mated with a 1 in. PVC pipe for installations purposes. A 1 in. female adapter socket with FPT threads is needed between the 31648 and 1 in. PVC pipe. This adapter socket is typically available at stores that sell PVC pipe.

Other Accessories

Use the 28840 for a direct connection to the NL240 or NL201.
Use the 28841 for a direct connection to an RF401A, RF450, or cell modem.
A150-L Single Sensor Terminal Case, Vented w/Desiccant
The A150 desiccated case is a small, self-contained junction box that allows the CS451V to be connected to a PWENC 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 CRS451V 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 29421 is a replacement lithium battery pack for the CRS451V.
The 6714 includes twenty 4-unit Silica Gel Desiccant Bags.
The 28878 is a replacement humidity indicator card. It provides a visual reference of humidity level inside the transducer.


A previously purchased CRS451V or CRS456V can be recalibrated using this service. Documentation for the recalibration is included, and the battery is replaced.
