MS-80 Pyranometer

EKO’s new generation sensors broke with the rules of traditional pyranometer architecture. The innovative patented design was inspired by the combination of latest technologies and state-of-the-art thermopile sensor, enabling a breakthrough in unprecedented low zero-offset behaviour and fast sensor response.

The compact sensor with single dome, based on a isolated thermopile detector and Quartz diffusor is immune to offsets and integrates all optional value added functions such as a ventilator, heater and different industrial interfaces. The heater and ventilator are suggested, particularly over areas impacted by dew, frost, snow, and dust.

The MS-80A is a MS-80 with built in 4-20mA converter and MS-80M with built in MODBUS converter are compatible to the industrial output standards. Due to the ultra low temperature dependency and exceptional non-linearity characteristics, the converter guarantees an optimal sensor performance, under any environmental conditions.

The all new MS-80S with smart sensor technology and onboard diagnostic functions which include relative humidity, temperature and tilt angle is now standard for all EKO smart sensors. It preserves the high accuracy of the sensor while complying with the various output standards used in the industry. The new Smart signal transducer allows selecting from 4 types of output in one unit MODBUS 485 RTU, 4-20mA, configurable 0-10mA / 0-1V with external optional 100Ω precision shunt resistor). The new electronics ensure a great benefit for system integrators.

The MS-80 pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. For each sensor the directional response and temperature dependency are measured and validated through a measurement report that comes with the sensor. EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025 / 9847.

The sensor has 5 years warranty, 5 years recommended re-calibration interval and no longer need to change the dessicant.
