DewPro MMR101 High-temperature Moisture Transmitter
Overview
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.
