The Vaisala DRYCAP® Dewpoint Transmitter DMT143 is a miniature dew point measurement instrument. The transmitter can be installed directly into pressurized systems at 50 bar (725 psia) maximum pressure. The long-term high performance is achieved with Vaisala DRYCAP technology.
♦ Miniature size dew point transmitter for e.g. small industrial dryer applications
♦ Vaisala DRYCAP® technology with auto-calibration
♦ Calibration interval of two years
♦ Dew point measurement range -70...+60 °C (-94...+140 °F)
♦ Accuracy ±2 °C (±3.6 °F)
♦ Withstands condensation
♦ Fast response time
♦ Compatible with Vaisala DRYCAP Hand-Held Dewpoint Meter DM70
♦ NIST traceable calibration (certificate included)
♦ Easy servicing and data transfer via the RS485 user interface
♦ LED alarm for exceeded dewpoint level
The sensor fully withstands getting wet, and therefore, the transmitter performs exceptionally well in applications that occasionally experience process water pikes, such as pipeline condensation during a system failure or start-up. The sensor is also highly resistant to particulate contamination, oil vapor and most chemicals, and is insensitive to the flow rate.
The calibration interval of the DMT143 is two years. Additionally, the Vaisala DRYCAP Hand-Held Dewpoint Meter DM70 can be used to confirm the performance of the DMT143 without disconnecting the transmitter. The auto-calibration software works on-line while the process is running. If the measurement accuracy is not confirmed, corrections are made automatically.
The DMT143 has a variety of features to choose from, including different output, installation options and alarm LED. Due to its small size and light weight, the DMT143 is quickly and easily installed in tight spaces or in small-size pipelines. The alarm LED indicates too high dew point in the process
