WIKA's comprehensive range of instruments has been extended with the introduction of the new PSD-30 electronic pressure switch. The new PSD-30 switch with integrated digital display and 4…20mA signal transmission combines three instruments in one.
The two switching set points on the PSD-30 can be set directly without the need for external programming devices. The PSD-30 can simultaneously transmit the pressure value directly via a 4…20mA signal as well as displaying the pressure on it's integrated digital display. Now control, local indication and remote monitoring can be carried out from one process connection and one convenient device.
WIKA now provides its new model PSD-30 pressure switches with an optional fieldbus independent communications interface, IO-Link. The point-to-point connection significantly reduces the expense of parameterisation, process monitoring and machine maintenance. By using the IO-Link, manual input of the various instrument parameters such as switch points, reset points and units is no longer required.
These are uploaded directly into the pressure switch from the central control system over a standard cable and can be reproduced at any time. This reduces the time required for commissioning or retrofitting. The operator is supported through a flexible choice of parameters and data documentation. IO-Link also enables diagnostics, giving precise information on the condition of the pressure switch. Thus any potential replacement of the instrument is only made if absolutely necessary.
Maintenance downtimes are therefore minimised. In addition to the advantages of the new interface, the high on-site functionality of the PSD-30 is available to the operator, if needed. This compact instrument is flexible for installation and among its features are three-key operation, uncomplicated menu navigation and an LED display with 9 mm high digits. As a result of its many options, the PSD-30 is suitable worldwide.
