Compact Pressure Sensors for Pneumatic Applications

February 15, 2010
The compact 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 fraction of the price. Measuring only 32mm x 30mm x 42mm, the compact sensor 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 color depending on the switching output status. The technology is based on a piezo-resistive measuring element. The silicon-measuring cell is insensitive to liquids and 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 pressure sensor can be mounted to flat surfaces, DIN rail or connected to plates or manifolds. The sensor can be connected to air lines through the G-1/8 port using a 6mm or 8mm tubing adapter or a 1/8-inch NPT adapter. Two models are available in ranges of -14.5 to 14.5 psi and -14.5 to 145 psi
