ОПИСАНИЕ ПРОДУКТА
SIEMENS QFM 2160 - Differential Pressure Sensor
The SIEMENS QFM 2160 is a precision differential pressure sensor from the QFM series, engineered for accurate measurement of air and non-aggressive gases in industrial HVAC and building automation systems. It provides a linear 0-10 VDC output signal proportional to the measured pressure difference, facilitating precise control and monitoring of ventilation systems, filter status, and fan operation. This device is critical for maintaining optimal air quality and energy efficiency in cleanrooms, laboratories, and commercial buildings.
