DewPro MMR30 - Moisture Transmitter

 

The DewPro MMR 30 is a compact, mid-range moisture transmitter probe designed specifically for refrigeration dryer monitoring. The MMR30 measures dew point at line or atmospheric pressure and installs easily on a dryer outlet header. 

Features

  • Simple loop-powered 4-20 mA connection
  • Proven polymer capacitive sensor technology for fast response and calibration stability
  • Integral filtering and flow regulation
  • Trouble-free indoor or outdoor mounting
  • Microprocessor in electronics Type 4X(IP67) enclosure
  • Optional integrated display
  • Optional DewPro communication software

Applications

The DewPro MMR31 provides a wide range of process humidity measurements, including relative humidity, dew point temperature, absolute humidity, and mixing ratio. These key parameters will help monitor and control critical processes.

 

Whether you need to improve product economy, increase product quality, maintain comfort levels, or preserve the properties of stored foods or other supplies, the DewPro MMR31 allows application flexibility.
