DMT143

DMT143 Miniature Dewpoint Transmitter for OEM Applications

The DRYCAP® Dewpoint Transmitter DMT143 is aminiature dewpoint measurement instrument. The transmitter can beinstalled directly into pressurized systems at 50 bar(725 psia)maximum pressure. Thelong-term high performance is achieved withDRYCAP® technology. The sensor fully withstands getting wet,and therefore, the transmitter performs exceptionally well inapplications that occasionally experience process waterspikes, suchas pipeline condensation during a system failure or start-up. Thesensor is also highly resistant top articulate contamination, oilvapor and most chemicals, and is insensitive to the flowrate.
