Differential pressure transmitters measure positive, negative, or differential pressure with an accuracy of within 2%.
They are installed in ventilation and air-handling equipment to measure the parameters of the air supplied to the power distribution room (PDR) or switchgear room (SGR).
Accuracy: 2% full scale (3% in the ranges -0 to 100 Pa, -120 Pa, and 10 mm; 4% for -00 and -60 Pa at 21.1°C).
Differential pressure is defined as the difference between the static pressure upstream of the diffuser and the static pressure at the narrowest point of the diffuser.
