Dual-channel differential pressure gauge leak detector

PD600 Series Differential Pressure Constant Volume Leak Detector

The PA600 series leak detector adopts a high-sensitivity differential pressure sensor, which has higher test accuracy; adopts a large-diameter air control valve, which has the advantages of fast inflation, good sealing, no heat, and long service life. The instrument has an intelligent test function. According to the characteristics of the differential pressure leak detector, it can effectively eliminate the errors caused by temperature and deformation through the learning and correction function, realize short-time precision measurement, and greatly improve the test efficiency. The system integrates new high-resolution analog-to-digital conversion technology, signal processing, automatic setup, rapid inflation and testing capabilities, an easy-to-operate interface and comprehensive communication technology. The machine adopts an intelligent control interface, which can quickly set the inflation time, pressure holding time, test time, and automatically determine the good product (GO)/non-defective product (NG), which greatly saves the test time;

Test schematic

Test principle: On the basis of differential pressure test, for products without inflation ports, partial pressure measurement can accurately determine the large leakage of the product. The partial pressure measurement method is also called the expansion measurement and the volume change measurement method.
