DewPro MMR 101

The DewPro MMR 101 is a high temperature loop-powered moisture and temperature transmitter. Housed in a Type4X enclosure, featuring simple two-wire or four-wire connection, and suitable for temperatures to 150ºC, the MMR101 is designed to withstand the harshest environments. Applications include power generation, food processing, paint and coating/finishing processes, clean room monitoring, pharmaceutical processing and other industrial applications. The DewPro MMR101 features proven polymer capacitive sensor technology for measurement over the entire range of 0 to 100% RH with an accuracy of ±2%, and a platinum TRD temperature sensor for temperature measurement from 0ºC to 150ºC. An optional integrated display with user interface provides full programming and diagnostic capability. In addition, the transmitter is FM approved intrinsically safe or explosion-proof for use in Class I, Division I hazardous areas.

DewPro MMR 31

The DewPro MMR 31 loop-powered mid-range moisture transmitter represents a simple, cost effective solution for mid-range moisture measurement. The MMR31 provides a wide range of process humidity measurements including relative humidity, dew point temperature, absolute humidity and mixing ratio. Whether looking to improve product economy, improve product quality, or maintain comfort levels, the MMR31's ability to measure these critical parameters provides an effective solution. The DewPro MMY31 features proven polymer capacitive sensor technology for measurement over the entire range of 0 to 100% RH (±2% for 0 to 90% RH, ± 3% for 90% to 100% RH). An optional integrated display with user interface provides full programming and diagnostic capability. In addition, users can perform simple field calibration using salt solutions. A patented second isolated loop for temperature measurement is also available.
