Barometers are sensors for measuring atmospheric pressure. The CX110P and CX115P models are destined to applications with connections to measurement systems (recorders, data loggers, etc.) that accept analogue signals; instead, the CX111P model is mainly destined for use with LASTEM’s BabucABC data loggers.

The barometers function according to the piezometric principle: a resistive film is deposited on a slice of silica with a bridge form; as the pressure changes, the slice will deform and consequently changes the system’s resistance.
The output can be reduced to sea level via trimmer on the CX110P and CX115P models and by software calibration on the data logger for the CX111P model. The CX115P model mounts a special thermal compensation system that significantly reduces thermal drift.
