( Brand: Ifm Efector ), ( Type: Sensor ), ( Manufacturer Part Number: PQ7809 )
The ifm efector pq7809 is a digital pressure sensor designed for use with compressed air applications. This sensor is a single-pole, single-throw (SPST) device, which means it has one normally open contact that closes when the prescribed pressure is reached. The sensor is capable of measuring pressures up to 14.6 bar (208.2 psi), making it suitable for various pneumatic systems.
The pq7809 features a robust stainless steel housing, ensuring durability in harsh industrial environments. It is equipped with a Vac-No functionality, which allows it to detect not only pressure but also vacuum or zero pressure. This can be particularly useful for applications such as discriminating between leaks in pneumatic systems.
The sensor works on a digital principle, providing highly accurate pressure readings. It features a built-in diagnostics function, allowing users to assess the health of the sensor via digital communication interfaces like CANopen, Modbus, and NPN/PNP output signal. The digital communication feature also enables quick identification and diagnosis of faults, improving maintenance efficiency.
The ifm efector pq7809 is designed to be easily integrated into various control systems. With a choice of electrical connection options, including 4-wire and 2-wire voltage-free variations, installation is flexible. Additionally, the sensor can be configured to suit individual application requirements, such as adjustable hysteresis value and switching point.
This digital pressure sensor is known for its high reliability, thanks to its overpressure and undershoot protection features. It can handle sudden pressure surges or vacuum conditions without being damaged. The robust design and advanced features make the ifm efector pq7809 an excellent choice for various pneumatic applications in industries such as automotive, food & beverage, and manufacturing.
