DewPro MMY30 Dew Point Transmitter
- Planar Aluminum Oxide Sensor Corrosion resistance, calibration stability, fast response
- Integral Filtering & Flow Regulation Ideal for monitoring moisture content
- Optional Integrated Display with User Interface Provides full programming & diagnostic capability
Overview
The DewPro MMY30 is a loop-powered transmitter with 4 to 20 mA output. The DewPro MMY30 is specifically designed to measure dew point or ppm in gases at line pressure or atmospheric pressure. The planar aluminum oxide sensor provides excellent corrosion resistance, longer calibration stability, quick response times, and an exceptionally low temperature coefficient. The optional integrated display with user interface provides full programming and diagnostic capability.
The DewPro MMY30 features an integral flow cell for filtration and flow regulation making it ideal for monitoring the moisture content in various process environments. Several options are available for the process connection allowing easy installation of the transmitter.
