COMPACT PRESSURE SENSOR DATA SHEET FCK The compact pressure sensor measures the pressure or absolute pressure of liquids, gases or steam, and outputs a current signal. A compact and simple structure procures high reliability and long-term stability. The instrument can be mounted on any of general industrial facilities, and is best suited for automation, labor-saving, efficient operation, etc. of equipment. FEATURES 1. Compact and simple structure facilitating an installation The structure is compact, lightweight and simple. Mounting is easy with direct screwing-in requiring no fixtures. 2. Abundant range of products Pressure sensors and absolute pressure sensors are available. Current output is usable. The pressure measuring range includes very low to high pressure. All these features destine the instruments to different applications. 3. Coping with environmental conditions The dust and water-proof structure complies with IEC IP65.
