Accessories for measuring atmospheric dew point

Environment pressure affects the value of dew point. When environment pressure is higher, water vapor condensate easier. Thus, dew point value in high pressure environment is higher than atmospheric dew point.
In process line, pressure could change and fluctuate easily, and leads to inconstant reading value. To avoid this problem, eyc-tech suggest user to measure dew point at atmospheric pressure (atmospheric dew point).
To help user measuring atmospheric dew point easily, eyc-tech provide related accessories, which including installation base for dew point transmitter, pressure regulator and flowmeter …etc. User can select accessories depends on installation. Please ask our sales personnel for further information.
Part number| Description
---|---
BASE-THS-001| Installation base(1/2“PT for transmitter), SUS304, Connection for air inlet and outlet: 1/4”PT
BASE-THS-002| Installation base(1/2“PF for transmitter), SUS304, Connection for air inlet and outlet: 1/4”PT
A schematic of installation is shown below. Using pressure regulator to regulate pressure to 1 atm, and adjust airflow to 1~5 LPM to have stable reading of atmospheric pressure.
