Page 3: Introduction
1 INTRODUCTION HD50CR-AS is a relative or differential low pressure transmitter and data logger de- signed for wall flush-mounting. Measuring range ±100 Pa. A silicon piezoresistive sensor with high accuracy and temperature compensation is used, which allows excellent linearity, repeatability and stability over the time. The auto-zeroing feature allows stable measurements over the time without the need to recalibrate. -
