ABSTRACT
This chapter discusses pressure sensors. It starts with calibration pressure gauges - gauges that use directly the pressure definition principle and hence can be used for calibration. It includes Bell type pressure gauge, Dead weight tester, U tube, well type and inclined tube manometer. For each of them the principle is explained and gauge examples are shown together with typical ranges and accuracies. The following section focuses on deformation gauges such as Bourdon tube, spring bellows and diaphragm gauges. It is followed by specialized gauges for low pressures - vacuum meters. Bolometric (Pirani) and ionization gauges are explained. The chapter is concluded by a section about correct pressure sensor placement.
