Differential pressure
Type 664
The differential pressure transmitters of the 664 series are suitable for low pressure measurement for the media air and neutral gases. The compact and robust pressure transmitter is based on silicon technology, which ensures good accuracy and long-term stability. The temperature compensation is from -20 to +70 °C and thus improves the accuracy. The compact housing dimensions are suitable for applications where size plays an important role. Especially during the ongoing Covid-19 pandemic, the type 664 is used in mobile and stationary equipment for emergency ventilation. As the centerpiece in ventilators, it ensures the continuous and precisely dosed ventilation of patients.
