GANN HYDROMAT DMT-8
Automatic moisture control before, during
and after continuous production processes
The measuring, recording and control system GANN HYDROMAT DMT- 8 measures the
mois-ture content of solid wood in form of boards using a pneumatically operated measuring
station and electronic signal amplifiers. Measurements are taken intermittently in cadence
with a follow-ing processing machine, where the board is stopped for a short moment.

Picture left shows the measuring and control unit
Hydromat DMT-8, while in the arrangement below
the Hydromat DMT-8 has been installed in a
bigger cabinet, together with a laser printer.

The complete measuring and control system HYDROMAT DMT- 8 in standard design
consists of a measuring and control unit, based on micro-processor technology, with touchscreen display for read-out and input, mounted in
a 19-inch switch cabinet, a signal amplifier unit
mounted in a steel-sheet box with emergency/
safety switch, a height adjustable electrode
support with pneumatically operated measuring
electrode as well as a connecting cable.1.5 m
long.
The measuring system can be equipped
optionally with an laser printer for printing out the
readings as numerical values or as a bar graph.
The printer can be installed on the side of the
measuring unit or, at dusty surroundings, in a
bigger switch cabinet together with the
measuring unit.

The figure left shows the pneumatically operated meashold-down device, measuring electrode with needle electrode attachment, measuring cable MK 10 and the signal
amplifier box. The measuring station can be supplied for
special applications without electrode support (only with a
fastening flange and pneumatic cylinder). In this design the
measuring pick-up can be installed also from below with
electrode operated in inverse direction.
