itsensor RGB203D LITEMETER Solar Irradiance Sensor

GENERAL DESCRIPTION

The LITE METER LM1-10V PRO is a solar irradiance sensor with strictly selected electronic components to ensure maximum precision also along with temperature changes.
This sensor has two signal outputs in voltage: 0 ÷ 10 V for solar irradiance and 0 ÷ 10V for temperature. Moreover, the solar irradiance signal is temperature compensated: this means that solar irradiance values are practically independent by cell temperature.

FEATURES

• Measurements:
  irradiance range:
  0 ¸ 1200 W/m2

• Outputs Voltage:
  0 ¸ 10 V for ¸ 0 ¸ 1200W/m2 factory calibrated
  0 ¸ 10 V, for ¸ -20 ¸ 80°C (V = 1.84 + 0.092 x T[°C]) guaranteed by design

• Output precision:v
  irradiance: Temperature
  ± 3,5%
  ± 1,5°C

• Working temperature:
  -30  +85 °C

• Supply:
  12 ¸ 30Vdc (see the scheme on page 2)

• Encapsulation:
  small microprismatic glass for photovoltaic modules and E.V.A

• Case:
  anodized aluminium with stainless steel screw-clamp to fix it on modules or montage profile

• Wiring:
  60 cm or 3m cable Ø 4.9 mm, conductors 4x 0,25mm², UV and high temperature resistant

• Connectors:
  4 + 1 GND loose pins ( or M8 4 pin)

• Dimensions:
  98x55x25 mm, with mounting bracket 112x55x66 mm

PIECE’S LIST

• Instrument with cable
• Aluminum fastening clamp
• Mounting screw for the fastening clamp
• Fixing screw fastening clamp-profile/modules

Important: the case presents a hole with a diameter of a few mm, this hole is terminated by a transpiring membrane whose purpose is the barometric compensation to avoid condensation.
DON’T PERFORATE. WARRANTY VOID IF REMOVED OR PERFORATED.

MECHANICAL FASTENING

insert the solar sensor with its fastening clamp to the chosen frame of a PV module representative of the PV installation as shown in figure 1. Screw the below bolt of clamp with a wrench until it appear stable.

CONNECTIONS
See table1 below. Once connected the irradiance values comes out instantly

Cabling: to get optimum sliding of the cable in wiring, we highly recommend use of sliding products.

MEASUREMENT
The temperature value has to be converted with the formula: V = 1.84 + 0.092 x T [°C].
As every LM1-10V PRO is factory calibrated, it’s not necessary to adjust gain and offset of datalogger but just insert pins on right positions of the datalogger with 0 ÷ 10V signal input provided.
The signals can be read also with a tester by selecting 0 ÷ 20Vcc range if supply Vdc is given to LM1-10V PRO solar sensor.
If in recording are encountered high level of interferences try disconnecting GND wire (#5).

CALIBRATION
It is recommended to send to the factory for verifying calibration after 2 years of outdoor work.
Some “inclusions” may be present and clearly visible into the protective encapsulation resin. This is due to the resin coating process and do not affect overall performance and/or accuracy.
