Sunshine Duration Sensor

Alat Meteorologi
LPSD18.1 Sensor for the measurement of the sunshine duration, referred to the 120 W/m2 threshold of direct radiation,
according to the WMO indications. This sensor has no moving parts. RS485 MODBUS-RTU output and voltage-free
contact output (CLOSED = direct radiation above the threshold, OPEN = direct radiation below the threshold). Power
supply 7…30 Vdc. It can be fixed to a mast with a suitable optional accessory or installed on a horizontal plane by
using the optional mounting base. Built-in levelling device. This sensor does not require adjustement of the position
during the year. Equipped with anti-condensation system. 8-pole M12 connector. On request 5 or 10 m standard
CP18… cables with 8-pole M12 female connector.

LPSD18.2 Sensor for the measurement of the sunshine duration, referred to the 120 W/m2 threshold of direct radiation,
according to the WMO indications. This sensor has no moving parts. RS485 MODBUS-RTU output, 0…1 Vdc
analog voltage output corresponding to 0…2000 W/m2 of direct radiation, digital voltage output (1V = direct
radiation above the threshold, 0V = direct radiation below the threshold). Power supply 7…30 Vdc. It can be fixed to a
mast with a suitable optional accessory or installed on a horizontal plane by using the optional mounting base. Built-in
levelling device. This sensor does not require adjustement of the position during the year. Equipped with anticondensation system. 8-pole M12 connector. On request 5 or 10 m standard CP18… cables with 8-pole M12
female connector.

LPSD18.3 Sensor for the measurement of the sunshine duration, referred to the 120 W/m2 threshold of direct radiation,
according to the WMO indications. This sensor has no moving parts. SDI-12 output and voltage-free contact output
(CLOSED = direct radiation above the threshold, OPEN = direct radiation below the threshold). Power supply 7…30 Vdc.
It can be fixed to a mast with a suitable optional accessory or installed on a horizontal plane by using the optional
mounting base. Built-in levelling device. This sensor does not require adjustement of the position during the year.
Equipped with anti-condensation system. 8-pole M12 connector. On request 5 or 10 m standard CP18… cables with
8-pole M12 female connector.

R Heating option for the installation in cold climates, for the removal of ice and snow. Heating activated below +6°C. Heating power consumption: 5 W @ 12 Vdc.

Base for the installation of the LPSD18… sensor on a horizontal plane. Two adjustable
feet and one fixed. It allows the inclination of the sensor up to 80° (with graduated
scale) with respect to the vertical axis, to fit the position of the sun at the latitude of the
installation site.

LPSD18.VK Support for the installation of the LPSD18… sensor on a Ø 40 mm mast. It allows the
inclination of the sensor up to 80° (with graduated scale) with respect to the vertical
axis, to fit the position of the sun at the latitude of the installation site. It allows the
rotation of the sensor on a horizontal plane.

LPSD18.19K Basic support for the installation of the LPSD18… sensor on a flat base. It allows the
inclination of the sensor (without graduated scale), to fit the position of the sun at the
latitude of the installation site. To be requested when ordering the sensor (it must be
assembled at the factory).
