LSI LASTEM have designed sensors for accurate readings and to offer the required output at the minimum time. In the same manner, the barometer is the sensor which is used to measure the accurate pressure.

The DQA240.1#C type is very suitable for the LSI LASTEM data acquisition systems. The DQA250 is the model that is suitable in the application where remarkable high accuracy is needed. In the DQA250 and DQA240 models the output will be 0ￜ1 V and the power supply is 10ￜ14 Vdc. Both models work on the piezoelectric principle, maximum pressure limit is 2000 hpa and the range lies between 800-1100 hpa. The thermal drift, power consumption, uncertainty, protection and calibration certificate will vary from each weather model.

LSI LASTEM's DQA223 model uses a thermo compensation system to deduce the thermal effect on a pressure measurement. This model has a different analogue outputs that are selectable locally with a dip switch. Uncertainty in the DQA223 model is 1 ha where DQA250 is 0.3 ha denote the high accuracy limit.
