Description

This Barometric Pressure Sensor uses a high-accuracy temperature-compensated piezoresistive silicon sensor. It gives precise measurements of atmospheric pressure in the range 500 hPa to 1200 hPa.

With an integrated temperature element, the sensor offers excellent thermal stability, providing consistent results across the entire operating temperature range (-40°C to +85°C).

It is suitable for all outdoor and indoor applications (e.g. clean rooms, internal combustion engines, laboratories) and can be used as a stand-alone sensor or as part of a larger environmental monitoring system with other sensors.

Housed in an IP67 enclosure, the sensor is ideal for remote applications. It requires very little power (10-30 VDC) and can be powered by solar cells.
