The Comptus A70 Series solar radiation sensors with transmitters are available in two models. The A70-A PAR Sensor measures photosynthetically active radiation (PAR) in the 400 to 700nm range. The A70-I Insolation Sensor measures solar radiation in the 280 to 2800 nm range. The signals from the sensors are scaled by the signal conditioner to provide the desired output.

Comptus A70 Series solar sensors and transmitters provide an analog signal output proportional to the phenomenon being monitored. All components have proven themselves rugged and reliable through years of field operation. These units can be used in conjunction with electronic data collection systems or for input to control systems.They are readily combined with meter relays to provide custom controls.

All systems are available with outputs of 0-1 mA, 0-1 V or 4-20 mA. All systems may be powered from either 24 VAC, 120 VAC, 230 VAC, 12 or 24 VDC. Comptus transmitters are available in a variety of packaging including steel JIC boxes meeting NEMA 12 standards, weatherproof fiberglass enclosures meeting NEMA 4X, IP66 and IEC 529 standards. NEMA 12 enclosures provide protection from dust for indoor applications, NEMA 4X enclosures may be used indoors or outdoors, and provide protection from corrosion, wind-blown dust, rain and ice. Track-mounted solar sensors are intended fro mounting inside an enclosure provided by the user. Where required, electrical connection to the sensor is via terminal block. A barrier strip is provided for connection to operating power. The system should only be used to monitor natural sunlight. Contact the factory regarding other light sources.

Comptus solar radiation sensors and transmitters are manufactured in the USA.
