CD42-T1AHP Transmitter (8" - 28")

A 4,000 PSI rated version of CDI's CD42-T1A, the CD42-T1AHP is an extremely durable stainless steel transmitter manufactured to exacting tolerances by CDI.

A face seal and through-hole bolts provide a sure seal to pressures of 4,000 PSI and it may be mounted in or on almost any type of pipeline pig and is recommended for pipeline diameters from 8" to 28".

This transmitter is guaranteed to operate for a minimum of 500 hours on 6 AA-Cell batteries. For long offshore commissioning projects where pigs can be in the line for months and years, a pressure switch option is available.

The tiny computer in the CD42-T1AHP allows you to easily switch between three stock transmission patterns, or if you're tracking a train of pigs the transmitter can be programmed to create any number of unique and easily identifiable patterns.

Whether rented or purchased, the CD42-T1AHP comes with:


• Stainless steel high pressure transmitter
