Namche Barometer
At the AWS Namche station the CX115P Lsi-Lastem barometer is connected with measurement system (recorder, data logger) that accepts analog signals.
The barometer functions according to the piezometric principle: a resistive film is deposited on a slice of silica with a bridge form; as the pressure changes, the slice will deform and consequently changes the system's resistance.
The CX115P model mounts a special thermal compensation system that significantly reduces drift.
Specific characteristic:
Range: 800 ž 1100 hPa (1 hPa=1 mBar)
Sea level correction range: -300...+2000 mt.
Thermal drift: 0,01 hPa/°C (-10..+60°C)
Linearity&Hysteresis: < 0,3% of the range
Overload: max. 2 Pa
Load resi stance: Current output types: <500W.
Power consumption: 3 W
Response time (T90): 1 ms
Environmental limits: -25 .. +60°C
Output connections: terminals
Weight: 650 gr.
Housing case material: Plastic
Protection: IP40 Downward cable outlet

The station was installed on October 2001. The sensors about air pressure are mounted on a 2m mast.
The barometer functions according to the piezometric principle: a resistive film is deposited on a slice of silica with a bridge form; as the pressure changes, the slice will deform and consequently changes the system's resistance.
The CX115P model mounts a special thermal compensation system that significantly reduces drift.
