To Our Customer
Thank you for purchasing the Dryer MasterAM3(Automatic Mini Moisture Manager) System. The
Dryer Master AM3 is a robust system that employs state logic for control. It is simple to use and can be
applied to most if not all grain moisture measurement applications.
The AM3is part of the Dryer Master family of moisture monitoring and moisture control systems that
have at their heart Dryer Master's stainless steel fin type capacitance based moisture sensors. These
sensors were initially developed to drive Dryer Master's industry leading computerized moisture
control systems, where they are placed at the inlet and the outlet of the dryer. With over 30 years of
field proven experience they are now being offered as part of the AM3moisture monitoring and state
logic control solution.
We trust that you will be pleased with the operation of the AM3and that you will enjoy benefits similar
to those provided by the world renowned Dryer Master

moisture control system.

1. Introduction
This document provides the operational specification for an on-line moisture display system with a
single sensor; product moisture and product temperature are displayed. Moisture control is achieved
using state logic. The system consists of a display unit and a moisture sensor. Both the display unit
and the sensor require less than 15 watts of power and are powered from a low voltage 24-volt direct
current instrumentation power supply. Depending on the options purchased the system may include
other components and devices.
Moisture measurement technology
The Dryer Master Moisture sensor measures the dielectric properties, in effect the capacitance of the
product in the vicinity of the sensor fin. This method is the most effective in measuring the total water
in a given volume of product. The installation ensures a large sample of product is presented to the
sensor at all times. This large sample contributes to a better product moisture representation than
other methods and generally provides a very good representation of the product in the total sample
stream. This technology is particularly suited to the measurement of product with moisture gradients.
A moisture gradient occurs any time product is processed either by heating or cooling but not limited
to either. The sensor’s robust construction and conservative installation specifications ensure long
product life.
Moisture control technology
The Dryer MasterAM3 state control technology employs a 3 state model triggered by user settable
moisture targets, time delays and speed set points for continues dryers. Instead of constantly
switching between a high and low discharge speed as used in many smaller on farm drying systems the
system switches between higher discharge speed triggered by drier product to normal speed, to lower
speed triggered by higher moisture product. Depending on the operating mode the 3 speeds can be
either individually manually set, set as a % of the normal operating speed, or a specific deviation from
the normal speed. The trigger points are actual moistures measured by the moisture sensor and
delays to activation are user settable from 1 second to 999 seconds or 16.65 minutes. The system can
also be configured for recirculation batch type dryers. Where the product is re- circulated in the dryer
until a specific moisture target is reached and the dryer is unloaded.
Information display
The information display is a micro PLC (Programmable Logic Controller) with an integrated graphics
LCD display and keypad. This combination of integrated items is also referred to as an OCS (Operator
Control Station). The Dryer Master Moisture sensor calibration software embedded in this device
provides the same reliability and accuracy previously once only available in the Dryer Master dryer
control systems.
