; L can be translated to a pressure measurement using the following formula,
; where m and b (in psi) are determined from device calibration sheet.
P=(m)*L + (b)

6. Maintenance
Campbell Scientific recommends that the CS431 be factory recalibrated and
checked every six months. Before a CS431 probe is sent to Campbell
Scientific, the customer must get an RMA (returned material authorization) and
fill out the Declaration of Hazardous Material and Decontamination form.
Transducer - all models: There are no user-serviceable parts.
Cable: Cable can be damaged by abrasion, sharp objects, twisting, crimping or
crushing and pulling. Take care during installation and use to avoid cable
damage. If a section of cable is damaged, it is recommended that you send your
sensor back to replace the cable harness assembly.
End Connections: The contact areas (pins & sockets) of Mil-spec connectors
will wear out with extensive use. If your application requires repeated
connections (in excess of 5000 connections) other types of connectors can be
provided. The connectors used on the CS431 are not submersible, but are
designed to be splash-resistant.
Desiccant Tubes: Inspect the Desiccant Tube at least once every
two months. The desiccant is a bright blue color when active
and dry; as moisture is absorbed, the color will begin to fade
until becoming white indicating full saturation and time to
replace. IMPORTANT
