Sensor for Solar Radiation and Temperature PT100 with pulse Digital outputs,4÷20 mA Analogical Outputs and Modbus RTUGSL-IT-DA

The composite sensor can detect solar irradiation values and temperature and send it to a datalogger through configurable outputs like pulsed digital or analogue ones, 4-20mA. The sensor allows
precise detection of two fundamental parameters for the evaluation of the performance of photovoltaic plants: irradiation and operating temperature of the panels.

By considering these measurements it is possible to define the real performance of the plant and detect any problems that can cause the real efficiency to vary from theoretical values.

The irradiation is detected by means of a sensor protected by an optical glass window inserted in a waterproof structure with an IP65 protection rating. Within the module the sensor temperature is also detected, which is useful for accurate compensation.

Detection of the temperature is performed by means of a PT100 probe interface externally mounted to module. For the connection, all types are considered: 2, 3 or 4 wires. (PT100 probe with 4 wires;
L = 2 mt OPTIONAL).

The pulsed digital outputs allow it to interface directly with the X-Meter or X-RWU data logger. The outputs can be selected as analogue 4-20mA to connect the device to any process controller
or data logger.

A standard insulated RS-485 serial ports is also available, which can be used to read the measured values using the Modbus RTU protocol (Not enabled for the basic model).
