The DewPro MMR30 (shown in Figure 1-2 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 . The placement of this ori fice determines whether the dew point
measurement is done at process (line) pressure (outlet orifice), or at
atmospheric pressure (inlet orifice).
Optional Display/User
Interface
The optional display/user interface feature allows the DewPro to be
configured to the user's specifications. See Chapter 4 for more
information.

1-2General System Information
November 2005
Theory of Operation
4 to 20 mA LoopThe 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. In the standard range,
4 mA corresponds to -15°C (+ 5°F) and 20 mA to +85°C (+185°F)
dew point temperature.
BypassIn dryer applications, the moisture sensor performs best when
mounted in a bypass. The built-in bypass of the DewPro eliminates
costly hardware associated with traditional sampling methods. The
DewPro installs easily into the process with its G ½ or ½” NPT-M
threaded connection.
Polymer SensorThe sensing element in the MMR30 is a silicon-based polymer that
uses the capacitance principle for the moisture measurement. The IC
chip includes the moisture sensor and appropriate integrated circuitry.
A platinum RTD temperature sensor is built in to provide temperature
compensation for maximum accuracy. The sensor element is
protected from condensation using a hydrophobic sintered filter.
CalibrationEach DewPro is factory calibrated against precise NIST certified
moisture references and has an accuracy of ±1°C dew point for dew
points above 0°C. Field calibration is possible with the use of a
moisture generator. Consult the factory for details.

The DewPro is designed to be mounted to pressurized
systems. Take necessary precautions when mounting or
removing the DewPro.
November 2005
• Mount the DewPro
particles or condensation from entering the bypass.
• Mount the DewPro
DewPro when removing it from the process pipe in case of
maintenance.
Do not over-tighten! The outlet fitting is connected to the
bypass block with a G 1/4 straight thread (with gasket)
which will seal if the fitting is simply hand-tightened. When
connecting an external device, counter the fitting with a
second wrench when tightening. If the inlet is equipped
with a G 1/2 straight thread and gasket, the seal is
obtained by simply hand-tightening the DewPro®.
If you are installing the DewPro into a pressurized system
(up to 10 bar), depressurize the system before installing or
removing the sensor. Pressurized systems require a
stainless steel compression fitting.

Installation Guidelines2-1
November 2005
Pressure DewpointRefrigeration 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.
Air Flow The DewPro is designed to measure the pressure dew point. By
restricting the flow at the outlet of the integral bypass with an orifice,
the sensor monitors the dewpoint at process pressure. The bleedoff air
to the atmosphere at 7 to 8 bar (100 psig), is approximately 70 cc/min.
(=4 l/h or =0.14 cfh). For smaller sized dryers of 3m
the air loss is only 0.002% of the air production and is negligible.
Despite the very low flow rate through the bypass as shown in Figure
2-1 on the previous page, the air sample in the DewPro bypass
chamber is refreshed every second due to the small volume design.
As a result, the sensor sees changes in moisture instantaneously.
Due to the low flow rate, the flow velocity is also very low at <0.01
m/sec. (=34m/h).The low flow velocity prevents the inlet filter from
clogging, since there is not enough kinetic energy to push dust
particles into the filter.

2-2Installation Guidelines
Method II - Orifice at
Inlet
November 2005
Figure 2-2: DewPro with Orifice Restriction at Inlet
In case the application requires the dew point measurement under
atmospheric pressure, the orifice flow restriction is to be mounted at
the inlet of the DewPro
®
bypass.This may not be typical for dryer
applications. The dew point reading will be lower since the water
vapor pressure is reduced by the factor of the pressure drop across the
inlet orifice.
®
In this configuration, the outlet of the DewPro
bypass is not flow
restricted and will be equipped with a 6 mm (1/4”) tube fitting. 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 GE Sensing can be used.
Installation Guidelines2-3
November 2005
Method III - No Flow
Restriction
Low Pressure Closed Loop
Figure 2-3: DewPro with No Flow Restriction
Closed loop systems, with dew points >-15 °C, may operate at a low
pressure. The air passing through the DewPro bypass is fed back to
the main stream after a pressure drop in the main line.
In this configuration, the DewPro bypass has no flow restriction at the
inlet and outlet. The outlet is equipped with a 6 mm (1/4”) tube fitting
to allow simple connection of the loop tubing.
2-4Installation Guidelines
November 2005
Method IV - Remote
Installation
In some cases there may not be enough room to install the DewPro
directly to the process pipe. The tube connection at the inlet allows
mounting the DewPro at a remote location, as shown in Figure 2-4
below. The functions of Methods I-III can be selected.
Figure 2-4: DewPro in Remote Installation
Mounting BracketsThe DewPro can be mo unted on a wall, a plate or a pipe using a
bracket available from GE Sensing, as shown in Figure 2-5 below.
Note: If the DewPro is equipped with an optional display/user
interface, please refer to Chapter 4.
Caution!
The DewPro system contains electronic components that
are susceptible to damage by static electricity. Proper
handling procedures must be observed during the
removal, installation, or other handling of internal boards
or devices.
System Configuration Figure 3-1 below shows various power supplies and displays for use
with the DewPro.
Figure 3-1: Power Supplies and Displays for DewPro
Designing the LoopIf users provide their own power supply, the voltage at the +/-
terminal of the DewPro should not fall below 12 VDC. The maximum
loop resistance is an important measure for selection of the supply
voltage. Each device connected to the loop causes a voltage drop. For
instance, using a loop-powered display with an input impedance of 50
Ohm will cause a voltage drop of 1 VDC at 20 mA using Ohm's law.
Connecting the loop to a PLC will cause a voltage drop across the
input.
When designing your loop, add up all voltage losses across the
devices connected to the loop and add 12 V. The sum will be the
minimum supply voltage required from the power supply. Calculate
with a 20% safety factor.

Electrical ConnectionFigure 3-4 below shows the DewPro wiring connections.
Figure 3-4: DewPro Wiring Connections
General Instructions1. Unscrew the cap on the unit.
2. Loosen the cable gland located on the side of the unit.
3. Feed the cable through the conduit opening.
Note: Use a standard signal cable size.
4. Retighten the metal cable gland to meet IP67 and to relieve any
stress on the wire.
5. Verify that a voltage between 12 and 28 V DC is across the
terminals marked + and -.
Note: This is the voltage that appears across the DewPro terminals,
not necessarily the power supply voltage due to voltage loss in
wire length, displays, and indicators.
6. In order to meet EMI/RFI immunity, a two-wire shielded cable
with a common foil shield layer is being used to power the
MMR30. Removing the insulation by 3” allows users to pull back
the foil, clamping it in between the metal cable gland. You must
connect the ground wire to the internal grounding screw.

Directions for Detecting
the Correct Error Code
(cont.)
Problem:The loop current is outside the range of 4-20 mA, as
shown on display or current meter. (In some cases, 22
mA can be ordered as the fault current.)
Solution:The process dewpoint is out of range. If the dewpoint is
above +85°C (+185°F), the current will go to 22 mA.
Apply dry air for 20 minutes. If the dewpoint doesn't
decrease, consult the factory.
If the dewpoint is below -15°C (+5°F), the current will go
below 4 mA and then to 22 mA as the fault current.
Expose the DewPro to wetter for several minutes. If the
error remains, the cause may be a defective sensor
assembly or an electronics malfunction. Consult the
factory.
Problem:There is no current.
Solution:Check the voltage and polarity across +/- terminals with a
DC voltmeter. If the voltage is within 12-28 V DC,
consult the factory.
Problem:The response time is very slow.
Solution:Verify the flow with an air flowmeter. If the orifice is at
the outlet of a 7 to 8 bar (=100 psig) process pressure, the
air flow should indicate 20 to 30 1/h (500 cc/min., 1 cfh).
If the flow is dramatically lower, the inlet filter may be
clogged. Remove the 2 micron filter and clean it with a
solvent or replace it.
Removing the FilterFigure 5-1 below illustrates filter parts for removal.
