High-temperature Moisture Transmitter – Dewpro® MMR101

The DewPro MMR101 is a high-temperature loop-powered moisture and temperature transmitter. The transmitter is housed in a Type 4X/IP67 enclosure and features a simple two-wire or four-wire connection. The DewPro MMR101 uses a proven polymer capacitive sensor to provide a humidity measurement range of 0 to 100% RH with an accuracy of ±2% up to 149°F(65°C). A platinum RTD temperature sensor delivers temperature measurements in the range of 32°F to 300°F (0°C to 150°C). The optional integrated display with user interface provides full programming and diagnostic capability. In addition, the transmitter is FM approved instrinsically safe/explosion-proof for use in Class I,II,III, Division 1 and 2, Groups A,B,C,D,E,F&G hazardous (classified) locations.
With an operating temperature up to 300°F (150°C), the DewPro MMR101 is ideally suited for the harshest applications. The transmitter can report moisture content in relative humidity, dew point temperature, absolute humidity, and mixing ratio. Applications include food processing, high temperature solids drying, paint and coating/finishing processes, pharmaceutical processing, and other industrial applications.
