Description |
Instrument type |
12 channel internet-enabled micropower wind energy data logger |
Applications |
• wind resource assessment • turbine power performance verification |
Sensor compatibility - counter channels |
• NRG #40 anemometer • rain gauge • opto anemometer • reed switch anemometer |
Sensor compatibility - analog channels |
• NRG 200P direction vane • NRG 110S temperature • Li-Cor 200SA pyranometer • NRG BP-20 absolute pressure (requires optional iPack power) • RH-5 relative humidity (requires optional iPack power) |
Data Collection |
Counter channels |
Channels 1 - 6 are always counter inputs: • channels 1 - 3 dedicated for NRG #40 anemometer or compatible • channels 4 - 6 use counter Signal Conditioning Modules (SCMs) to configure the channel for a particular sensor |
Analog channels |
Channels 7 - 12 are always analog inputs: • channels 7 and 8 dedicated for NRG 200P (potentiometer) direction vane • channels 9 - 12 use analog Signal Conditioning Modules (SCMs) to configure each channel for a particular sensor |
