Compact PQ Series pressure sensors

May 2014 Sensors & Transducers

The compact PQ Series pressure sensors from ifm electronic are designed for pneumatic applications typically found in robotics and material handling applications. They precisely measure the full range of pressure and vacuum typical in these applications. The cube-shaped sensors easily retrofit traditional pressure switches at a fraction of the price. Measuring only 32 mm x 30 mm x 42 mm, they can be installed in areas with limited mounting space.

Application parameters are established using two pushbuttons. The bright, four-digit display indicates system pressure and can be clearly seen from long distances. The sensor features two programmable switching outputs or one switching and one diagnostic output. In addition, the values can be programmed to change colour depending on the switching output status.

The technology is based on a piezo-resistive measuring element. The silicon measuring cell is insensitive to liquids such as condensed water and other deposits that might occur in the system. The cell changes resistance when pressure is applied. The stress induced in the cell is transformed into an electric signal that is proportional to the pressure. The silicon measuring cell guarantees a high overload resistance as well as an accuracy of ± 0,5%.

For mounting purposes, the PQ pressure sensors can be fixed to flat surfaces and profiles using two M4 drill holes located in the front of the sensor. They can be mounted to a DIN rail or connected to plates or manifolds using ifm’s robust DIN rail bracket. They can be connected to air lines through the G-1/8 port using a 6 mm or 8 mm tubing adaptor or a 30 mm NPT adaptor. Two models are available. The PQ7809 has a measuring range of -1 to 1 bar and the PQ7834 has a measuring range of -1 to 10 bar. Electrical connection is made through an M8 Pico DC connector.
