Sartorius PMD300P and PMD301P

Online Moisture Analysis in a Fraction of a Second

The moisture analysis systems from the

Sartorius PMD300 series have been

designed for online, in-process analysis.

Through the use of microwave resonance

technology, moisture content can be meas-

ured in less than one second. The system

averages the individual measurements over

a user-defined period. Then they are sent

over the appropriate interface to a PC,

switch cabinet or a PLC controller. Both

core and surface moisture content are

measured. The analysis is non-destructive

and is not influenced by the color, density

or surface characteristics of the sample

material.

Sensors

A wide variety of sensors is available for

the PMD300 series. This way, the analysis

method can be customized to the sample

and process as each situation requires.

Depending on sensor type, the measuring

range is between a moisture content of

0.1% and 60%.

Ultrasensitive planar sensors, featuring a

special ceramic surface, are especially suit-

ed for use in assembly lines or in hoppers.

Due to their compact form and high pro-

tection rating, all sensors can be used in

the food industry. The diameter of the

sensors' measuring field is between 50 mm

and 130 mm.

Bypass sensors are especially suited for

pourable or granulated products that are

transported through pipes. Intake and dis-

charge valves controlled by the PMD301P

extract a defined sample amount, measure

it and then return it to the main current.

Optional functions also allow density to be

measured together with moisture.

A special fork sensor is available for

non-contact analysis. The sample is sent

between two sensor surfaces without it

touching the surface of the sensors.

Ex-protected versions are available for

all sensor types.

Applications

Monitoring and retraceability:

These versatile analysis systems can be used

in a variety of locations. For example, they

can be used in the incoming goods depart-

ment to analyze raw materials continuous-

ly and document the results. Instead of

doing spot checks, the entire batch is mon-

itored without interruption. (Meets IFS V5

requirements.)

Optimizing energy consumption:

A significant factor contributing to the

success of many processes is exact and

immediate moisture analysis. This is why

online moisture measurement is often used

in baking and drying processes. The ideal

conditions for drying and baking processes

can be met by continuously monitoring

moisture content without loss of time. The

temperature in the oven, air supply or con-

veyor belt speed are adjusted to the current

moisture content of the product. This lets

you save valuable energy.

Time management

Frequently, a predefined moisture content

must be reached before proceeding to the

next step in the process (batch processing).

This is possible using Sartorius' online mois-

ture analysis systems because they measure

moisture content continuously and send

them to the controller without delay. When

the target moisture content has been

reached, the process will go on to the next

step instantaneously and automatically.

Online moisture analysis makes your

process efficient and transparent.
