The Panametrics DewPro MMR101 moisture transmitter is a high-temperature loop-powered moisture and temperature transmitter housed in a Type 4X/IP67 enclosure. It features a simple two-wire or four-wire connection.

The MMR101 uses a proven polymer capacitive sensor for humidity measurement from 0–100% RH with ±2% accuracy up to 65°C. A platinum RTD temperature sensor measures from 0 to 150°C. An optional integrated display with user interface provides full programming and diagnostic capability. The transmitter is FM approved intrinsically safe/explosion-proof for Class I, II, III, Division 1 and 2, Groups A, B, C, D, E, F, & G hazardous locations. It can report moisture content in relative humidity, dew point temperature, absolute humidity, and mixing ratio. Applications include food processing, high-temperature solids, drying, paint/coating, pharmaceutical, and various industrial processes.
