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.

Lineage

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.

Specific characteristic:

Range: 800 ž 1100 hPa (1 hPa=1 mBar)

Sea level correction range: -300...+2000 mt.

Linearity&Hysteresis: < 0,3% of the range
