DMT143L online dew point meterBriefly describe

The online dew point meter adopts Vaisala(Vaisala)DRYCAP®sensorDMT143LDew point transmitter is a compact dew point measuring instrument that can be directly installed on50 bar(725 psia)In the pressure system. vaisala(Vaisala)DRYCAP®Sensor technology has long-term high-performance performance.

This sensor is resistant to humid environments, thereforeDMT143LThe transmitter can perform very well in industrial applications with water splashes, including pipeline condensation during process system failures or start-up phases. The sensor is also highly resistant to particulate impurities, oil and gas, and most chemical gases, and is not sensitive to changes in flow rate.
