Pyramid Barometer

At the AWS Pyramid Laboratory Observatory 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.

Technical 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
