This extremely accurate, Swiss made sensor contains the same pressure sensor already in use in Adcon's LEV1 water level sensor. The fully temperature compensated piezoresitive sensor element performs with a 0.1% accuracy across the whole range. The sensor itself is encapsulated in a robust Polycarbonate housing (meeting WMO requirements), protecting the sensor element from the effects of wind gusts that can cause incorrect readings. To ensure that pressure levels inside and outside the casing are equal (and that water ingress is prevented), the unit has a high-capacity Goretex vent.
The unit is supplied with a stainless steel clamp and bracket to enable mounting to the pole of a weather station. The sensor connects to a telemetry unit (of the A723 or A733 product families) via a shielded 3m cable with a 7-pin Binder jack. The BP1 has very low power consumption and produces an analogue output signal of 0,1 - 2,5VDC.
