OEM pressure switch with display Model PSD-4-ECO WIKA data sheet PE 81.69 OEM pressure switch with display, model PSD-4-ECO ■ Special-purpose machine building Special features ■ Good/bad indication through parameterisable digital display (red/green) ■ Compact size enables easy installation in narrow spaces ■ Optimised design makes OEM machine integration easier ■ Designed for rough demands of up to 50 g shock and -40 ... +125 °C [-40 ... +257 °F] The model PSD-4-ECO is a programmable electronic pressure switch designed specifically for OEM customers. With IO-Link 1.1, the cost-effective and reliable model PSD-4-ECO is a future-proof automation solution. Through individual factory pre-configuration, the pressure switch can also be quickly and simply integrated into the machine without any programming effort. With the model PSD-4-ECO pressure switch, it is very easy to determine if the system is operating within the desired pressure range. The instrument can be parameterised such that the digital display lights up green when the value is within the defined pressure range and red if not. In this way, problems can be identified early. With a diameter of 29 mm, the model PSD-4-ECO is very slim. Through the arrangement of the electrical output, it can be installed so that it uses little space. The display head can WIKA data sheet PE 81.69 • 07/2019 be rotated through 335° and the display tilted electronically through 180°, so that the pressure display is always aligned towards the user. The pressure switch is specially adapted to the requirements of OEM series production. For example, units of 25 pieces reduce the packaging material and make handling easier. Customer-specific pre-configuration by WIKA or automated parameterisation via IO-Link 1.1 saves time and simplifies the integration process. Tough: The model PSD-4-ECO pressure switch is designed for medium temperatures from -40 ... +125 °C. In addition, it withstands mechanical shocks up to 50 g and high electrical loads. This makes it a highly economical and reliable solution. ^ Part of your business Data sheets showing similar products: Electronic pressure switch with display; model PSD-4; data sheet PE 81.86 Pressure sensor with IO-Link; model A-1200; data sheet PE 81.90

The stated measuring ranges are also available in kg/cm2 and MPa. Special measuring ranges between 0 ... 0.4 and 0 ... 1,000 bar (0 ... 10 bis 0 ... 7,500 psi) are available on request. Special measuring ranges have a reduced long-term stability and higher temperature errors. The overload safety is based on the sensor element used. Depending on the selected process connection and sealing, restrictions in overload safety can result. Deviating temperature errors and long-term stability with respect to the selected measuring range apply here. 7-segment LED, 2-coloured red/green, 4-digit, 8.9 mm...
