Festo Piezoresistive Pressure Sensor, 30V DC, -1 to 1 Bar - SPAN-B2R-R18M-PN-PN-L1 Monitor the air pressure in your industrial systems with this Festo pressure sensor. It monitors the flow of air and non-corrosive gases using a piezoresistive system that delivers reliable results. A small supply voltage of 30V DC means you can operate it with minimal power supply, helping to conserve energy. And thanks to an IP40 (ingress protection) rating, you can be sure the enclosure is adequately sealed against damage from objects up to 2.5mm in size. • Maximum operating pressure of 1 bar, for effective measurement in high-pressure systems
• Broad operating pressure range of 0°C to +50°C for reliable use in diverse environments
• Multiple mounting options to aid quick installation
• Illuminated LCD (liquid crystal display) screen for highly visible data readings Applications • Safety installations
• Food production industries
• Gas plants How does the piezoresistive measurement of this pressure sensor work? The key material in this piezoresistive pressure sensor is a semiconducting silicon that reacts to pressure. When the silicon senses a drop or increase in the movement of the pneumatic component, it automatically becomes resistant to the electrical current and triggers a data output in the pressure sensor.
