The PQ Series pressure sensors precisely measure the full range of pressure and vacuum found in pneumatic applications such as those in robotics and material-handling applications. The cube-shaped pneumatic sensor measures only 32 ×30 × 42 mm for mounting in tight spaces.Application parameters are established using two pushbuttons. A bright, four-digit display indicates system pressure. The sensor features two programmable switching outputs or one switching and one diagnostic output. The values can be programmed to change color depending on the switching-output status — red if output 1 is switched, green if output 1 is not switched.Two models are available. The PQ7809 has a –14.5 to 14.5-psi measuring range and the PQ7834 has a –14.5 to 145-psi range.ifm efector inc., 782 Springdale Dr., Exton, PA 19341, (800) 441-8246, www.ifm.com/us
