Mô tả

The PRSMD is a differential pressure gauge with an integrated pressure switch, featuring easy installation and on-site adjustable switch points without the need for external power. Designed for non-flammable and non-corrosive gases, it is commonly used in HVAC building automation systems for filter, fan, and duct pressure monitoring. With measuring ranges from 20 to 5000 Pa and ±2% F.S. accuracy, the unit features a silicone diaphragm, PC housing, IP54 protection, and a service life exceeding one million switch operations. The built-in SPDT contact supports up to 1.5 A @ 250 VAC or 1 A @ 30 VDC for reliable control performance.
