The PA-699 is a differential air pressure sensor incorporating a proved ceramic fulcrum lever technology. They deliver calibrated, temperature-compensated sensor signals, available as standard voltage or current outputs. They are ideal for registering low air flow in air conditioning systems and for the measurement of fine pressures in environmental, laboratory and clean room application (air and non corrosive gases).
The PA-699 is a differential air pressure sensor designed for precise measurement of pressure differences in various applications. The PA-699 can provide a linear analogue voltage (0-10V) or current (4-20mA) signal proportional to the measured differential air pressure, which can be set using Dip Switches to three different pressure ranges on each sensor. This sensor employs a highly accurate sensing element to provide precise readings over the measured differential air pressure. Its durable construction and stable performance make it suitable for demanding environments.
The PA-699 is solution for monitoring airflow, filter performance, and room pressure differentials and commonly used in HVAC systems for monitoring filter clogging and air flow rates, in cleanrooms and laboratories to maintain critical pressure differentials, and in industrial processes requiring accurate measurement of pressure differences for control and monitoring purposes.
