Unpacking and Inspection Upon receipt of the DewPro MMR30, examine the shipping carton for broken or open packing, distortion, or any other evidence of mishandling. If inspection indicates damage to the unit or any of its components, notify the carrier (within 15 days of delivery) and request an inspection. -
Page 10: Introduction
1.2.1 Unit Description The DewPro MMR30 (shown in Figure 2 below) is a loop powered mid-range moisture transmitter. The transmitter includes a sensor element, a flow chamber, a weatherproof enclosure, microprocessor electronics, and assorted fittings, all in a compact assembly. In most cases, either the inlet or outlet port includes an orifice to regulate the flow. -
Page 11: Theory Of Operation
4 to 20 mA Loop The DewPro MMR30 microprocessor controlled electronics operate with a DC voltage supply from 12 to 28 VDC. At the nominal 24 VDC supply, the maximum loop resistance is 600 Ohm. The signal is represented by the 4 to 20 mA loop current and is directly proportional to the dewpoint range in °C or °F. -
Page 12: Dimensions
Chapter 1. General System Information Dimensions Choose a mounting location which allows enough clearance for the use of tools. Figure 3 below shows installation dimensions for a standard DewPro, while Figure 4 below shows the dimensions for a DewPro with the optional display/user interface. -

Chapter 2. Installation Guidelines Chapter 2. Installation Guidelines General Hints CAUTION! Before installation, please read all instructions. The DewPro is designed to be mounted in pressurized systems. Take the necessary precautions when mounting or removing the DewPro. ® • Mount the DewPro vertically whenever possible to prevent particles or condensation from entering the bypass. -

Chapter 2. Installation Guidelines Method I - Orifice at Outlet Figure 5: DewPro Installation with Orifice at the Outlet 2.2.1 Pressure Dewpoint Refrigeration air dryers producing general instrument air are typically specified with a pressure dewpoint rating. The majority of dryers operate in a dewpoint range between +2°C to +10°C (+35°F to +50°F). A pressure of 7 to 8 bar (= 100 psig) is very common. -
Page 15: Method Ii - Orifice At Inlet
In order to prevent back diffusion of water vapor from the ambient air, five feet of exhaust tubing should be mounted to the tube fitting, or, better, a diffusion coil from Panametrics can be used. DewPro® MMR30 Installation & Operation Manual... -
