Model A70-I Pyranometer with Transmitter

Accuracy: ± 5%
Sensor:     LI-200SZ
Use: General Monitoring 

The Comptus Silicon Pyranometer measures both direct and diffuse insolation. The pyranometer output responds to the cosine of the angle between the sensor and the light source. The signal from the sensor is scaled by the signal conditioner to provide the desired output. The system should only be used to monitor natural sunlight. Contact the factory regarding other light sources.

The A70 Series provides an analog signal output proportional to the phenomenon being monitored at an economical cost. All components have proven themselves rugged and reliable throughout many years of field operation.

These units are 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 or 12 - 24 VDC. The instruments are available in a variety of packages including steel JIC boxes meeting NEMA 12 standards, weatherproof fiber glass enclosures meeting NEMA 4X, IP66 and IEC 529 standards and track mounted versions. NEMA 12 enclosures provide protection from dust for indoor applications. NEMA 4X enclosures may be used indoors or outdoors. They provide protection from corrosion, wind blown dust and rain and are 
undamaged by ice. Track mounted versions are intended for 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.
