Vaisala DMT143L Miniature Dew Point Transmitter

Vaisala DMT143L Long Probe Version dew point transmitters are designed with OEM applications in mind such as compressed air dryer lines. Vaisala DMT143L is easy to integrate and can be used in conjunction with the Vaisala DM70 portable device. Vaisala DMT143L replaced Vaisala’s discontinued DMT242 dew point transmitter.

Vaisala DMT143L DRYCAP® Dew point Transmitter is a compact transmitter designed to monitor very dry conditions such as in desiccant dried compressed airlines, transformer, and plastics drying applications, as well as in nitrogen-purged systems. Knowledge of the real dew point, not just system temperature, ensures high-quality air in your system at all times and enables optimization of your dryer capacity. DMT143L autocalibration function provides excellent long-term stability,  and the Sensor Purge feature allows for rapid response from ambient to dry process conditions. The transmitter is resistant to compressor oil and most other chemicals. DMT143L designed for extreme conditions hence can be installed directly into pressurized systems at 20 bara (290 psia) maximum pressure. Sampling cell adapters are also available for pressures up to 10bar.
