PM36 TILT PLATFORM SPECIFICATIONS
Automatic platform with data amovible storage in-situ.
Upgraded platform with respect to the initial to obtain Quality measurements.
1.1 Environmental specifications
- Storage :
Temperature range for storage (without the battery) : -30 to + 70°C.
Humidity range for storage : 5 to 95% without any condensation.
The battery is a lead acid sealed battery which does not
withstands very low and high temperatures without any deterioration. Maximum
temperature admissible for the battery: 40°C.
- Running conditions :
Operating temperature range : -20 to +70°C.
Protection degree of the cabinet : IP66. Although the sealed
enclosure is weatherproof, ELTA recommends to protect it with a simple
cover against direct solar radiation to avoid high and fast temperature
elevation and rain.
Humidity range for operating : 5 to 95% without any condensation.
- The solar panel must be cleaned regularly and be exposed
to the sun with a minimum 15° elevation.
The sensors have specific recommendations, see their
- Connections :
Type BULGIN Bucaneer series.
Degree protection when the connections are protected with
their caps : IP66.
1.2 Electrical specifications
- Power supply :
Battery 12 VDC / 38 Ah included in the cabinet.
Solar regulation included on the PM36 board.
Solar panel input : 12 VDC - 5 A. Accepts up to 25 VDC with
100 mV noise.
Platform ON, battery connected, by plugging the solar panel
Right functioning : from 11 to 15 VDC on the battery input.
Power requirements with 12 VDC : less than 15mA with
S(all)=1 heure, P = 1 heure, with a storage once per hour.
- PH36 Tilt board :
Processor : 16 bits MCS251 Intel family running at 3.6864
MHz with a low power consumption mode.
Battery input range : 6 VDC to 25 VDC protected against over
voltage and against polarity inversion with limiting diodes.
Solar panel input : 12 VDC -5 A. Solar regulation integrated
with automatic cut off when the voltage of the battery becomes superior
to 14.4 Volts.
Power requirements with 12 VDC : less than 10 mA in Idle
mode, less than 40 mA in active mode.
Memory Unit link : RS232 serial connection with hardware
control. V28 levels. Power of the memory unit controlled ON/OFF. Current
consumption less than 400 mA when activated.
1 analog input for low voltage less than 100 mV,
3 analog inputs for tension or loop measurement. For each
: 16 bits resolution on a 2 Volts input range (or 4-20 mA. True accuracy
of 14 bits.
1 linear analog input for RTD PT100 type sensor, range -10
to +50°C. Resolution better than 0.1°C, 13 bits. Accuracy of 0.3°C
all errors included : probe 1/3 class A, measurement error...
