Due to its wide measurement range and excellent long-term stability, Vaisala DRYCAPâ Dew Point Transmitter DMT143L is an ideal choice for low dew point industrial applications, such as compressed air dryers, plastic dryers, and other OEM applications.
Vaisala DRYCAP Dew Point Transmitter DMT143L is a miniature dew point measurement instrument.
The transmitter can be installed directly into pressurized systems at 20 bar
(290 psia) maximum pressure. It is designed for extreme conditions.
DMT143L incorporates Vaisala DRYCAP thin film polymer sensor and auto- calibration software. The standard sensor choice for dry gases and desiccant dryers is the DRYCAP 180M, and for more humid applications such as refrigeration dryers, the DRYCAP 180S is optimal.
The sensors fully withstand getting wet, and therefore, the transmitter performs exceptionally well in applications that occasionally experience process water spikes, such as pipeline condensation during a system failure or start-up.
The sensors are also highly resistant to particulate contamination, oil vapor, and most chemicals, and insensitive to the flow rate.
Long Calibration Interval
The calibration interval of DMT143L is two years. Additionally, Vaisala DRYCAP Handheld Dew Point Meter DM70 can be used to confirm the performance of DMT143L without disconnecting
the transmitter. For any adjustment needs, the transmitter can be sent to Vaisala Service.
The auto-calibration software works online while the process is running. If the measurement accuracy is not confirmed, corrections are made automatically.
DMT143L has a variety of features to choose from, including different output and installation options, and alarm LED.
Due to its small size and light weight, DMT143L is quickly and easily installed in tight spaces or in small-size pipelines.
The alarm LED indicates too high dew point in the process. The trigger point is preset at the factory. It can be later adjusted with Vaisala DRYCAPâ Handheld Dew Point Meter DM70, or the convenient Vaisala Insight PC software for Windowsâ. Insight PC software can also be used for other configuration options (see www.vaisala.com/insight).
