DPT-21 \/ DPT-22 \u2013 Programmable Gas Humidity Transmitters<\/h2>\n

DPT-21<\/strong> and DPT-22<\/strong> are modern, microprocessor-based transmitters designed for precise gas humidity measurement, expressed as dew point temperature, relative humidity, water vapor content (ppm), or degrees Fahrenheit. The devices convert the signal from a ceramic capacitive sensor into a standard 4\u201320 mA current signal.<\/p>\n

The transmitters are available with two types of process connections:<\/p>\n
