General System Information
The DewPro MMY30 trace moisture transmitter (shown in Figure
1-2 below) is a loop-powered dewpoint measuring device. The
transmitter includes a sensor element, a flow chamber, a weather-
proof 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 orifice
determines whether the dew point measurement is done at process
(line) pressure (outlet orifice), or at atmospheric pressure (inlet
orifice). A 2 micron sintered inlet filter prevents particles from
entering the device.
The optional display/user interface feature allows the DewPro to be
configured to the user's specifications. See Chapter 4 for more
information.
