OTT HydroMet - Model ADCON BP1 - Barometric Pressure Sensor
From ADCON - Sensors
High accurate Barometric Pressure Sensor. Temperature dependencies and non-linearities of the sensor are mathematically compensated for, up to 80°C. The sensor has a very low power consumption and produces an analogue output signal of 0,1 ... 2,5VDC.
The piezoresitive sensor element is fully temperature compensated and performs with accuracy better than 0,1%FS across the whole range. According to WMO requirements the sensor itself is encapsulated in a robust polycarbonate housing, which will protect the sensor element from erroneous readings caused by wind gusts. A high-capacity Goretex vent makes sure that pressure inside the case equals outside pressure, and that water ingress is prevented.
The sensor box is mounted to the pole of a weather station by means of a mounting bracket and clamp supplied with the product. A shielded 2m cable with a 7-pin Binder jack connects the probe to any RTU of the A723, A733 and A75x product families.
