The PCE-P50 is a differential pressure meter designed for measuring overpressure, underpressure, and differential pressure in air and non-corrosive gases. It features a 9 V DC power supply, either via battery or optional power converter, and an RS-232 interface for data transfer to a PC with accompanying software. The device has an impact-resistant ABS housing measuring 182 x 72 x 30 mm and weighs 150 g. It offers nine selectable pressure units and a backlit LCD display with min/max memory and data hold functions. The pressure range supports ±100 psi, ±6900 mbar, ±200 inHg, and other units, with a resolution of up to 0.1 and an accuracy of ±0.3% of full scale at +25°C. The operating temperature range extends to +50°C, and overload protection is twice the full-scale range.
Gauge pressure is measured relative to the ambient atmospheric pressure. Thus, changes in the atmospheric pressure due to weather conditions or altitude directly influence the output of a gauge pressure sensor. A gauge pressure higher than the ambient pressure is referred to as positive pressure. If the measured pressure is below the atmospheric pressure, it is called negative or vacuum gauge pressure.
Although most gauge pressure sensors technically are differential pressure sensors — measuring the difference between the media and atmospheric pressure — true differential pressure sensors are used to identify the difference between two separate physical areas. PCE-P50 features two pressure ports and a differential pressure function for measuring true differential pressure.
