5.8 Mounting and assembly recommendations

Please read the following recommendations carefully.

• The clearance above the metal lid shall be 0.1mm at minimum

• For the device housing appropriate venting needs to be provided in case the ambient

pressure shall be measured; if waterproof packaging is needed, venting can be

accomplished by a vent element with a membrane like Gore-Tex

(TM)

• Liquids shall not come into direct contact with the device

• During operation the sensor is sensitive to light, which can influence the accuracy of the

measurement (photo-current of silicon); therefore, the hole in the top lid shall not be

exposed to direct light during operation

• The BMP085 shall not the placed close the fast heating parts. In case of gradients

> 3°C/sec. it is recommended to follow Bosch Sensortec application note ANP015,

"Correction of errors induced by fast temperature changes"; please contact your Bosch

Sensortec representative for details

• For further details, please refer to the BMP085 handling, soldering & mounting

instructions manual that is also available from Bosch Sensortec
