Pressure sensor for pneumatic applications
May 2010
Pneumatics & Hydraulics
ifm electronic’s compact PQ Series pressure sensors are designed for pneumatic applications typically found in robotics and material handling applications. The sensors precisely measure the full range of pressure and vacuum typical in these applications. The cube-shaped pneumatic pressure sensor easily retrofits traditional pressure switches at a cost effective price, while measuring only 32 x 30 x 42 mm makes the compact units easy to install 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 (eg, red if the output is switched; green if it is not.)
The technology is based on a piezo-resistive measuring element. The silicon measuring cell is insensitive to liquids (eg, condensed water) and deposits that might occur in the system. The cell changes resistance when pressure is applied, which is transformed into an electric signal 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 sensor can be fixed to flat surfaces and profiles using the sensor’s two M4 drill holes located in the front of the sensor. The PQ can be mounted to a DIN rail or connected to plates or manifolds using ifm’s robust DIN rail bracket. The sensor can be connected to air lines through the G-1/8 port using a 6 mm or 8 mm tubing adapter.
Two models are available. PQ7809 has a measuring range of -14,5 to 14,5 psi and the PQ7834 has a measuring range of -14,5 to 145 psi. Electrical connection is made through an M8 Pico DC connector.
