HMD
- hot metal detector - a device only detects the exceeding signal amplitude of photocells
over the set threshold. It does not matter if the field of view of the sensor is an edge of the
material. It is necessary to limit field of view (depending on site conditions) by the appropriate
mechanical shutters or cover. (The basic limitation of the field of view is done by shield inside
the sensor - max viewing angle is necessary to specify when ordering).
3. General description
SDIS is a standalone sensor, heavy duty and easy to assembly and commissioning.
Its basic features are:
3.1
Mechanical
:
hermetically sealed, accurately machined housing made of aluminum alloy.
suport wall with mounting stand, adjustable in both directions, adapted to the cooling
unit with water and blowing air windscreen to prevent pollution.
connection of water and air in the supporting wall - when necessary the sensor can be
easily replaced without disconnecting water or air.
3.2 Electrical:
connection of all electrical signals via one connector
control using display and buttons
o
alphanumeric LED display to show parameters
o
4 buttons for easy parameter setting
o
3 LEDs to display the status:
green - flashes when the unit is in operation
yellow - indicates the presence of material the field of view
red - warning or malfunction of the unit
built-in diagnostics unit:
o
detection of exceeding the internal temperature over 60 ° C
o
detection of a motor speed failure
o
detection of power failure
