The WIKA PSD-4 electronic pressure switch
Featuring high levels of accuracy and minimal long-term drift, the WIKA PSD-4 electronic pressure switch is recognised as a universal solution for industrial automation tasks, under harsh conditions.
The unit also has European Hygienic Engineering and Design Group, or EHEDG, and 3-A certification, making it particularly suitable for industries with high levels of hygienic requirements.
The pressure switch is said to have an accuracy of <± 0.5% and minimal long-term drift, or amount of change in readings, ensuring an accurate representation of the process pressure for more than 100-million load cycles. The unit is available with a digital output signal as well as a switchable and scalable analogue output. it can also be monitored by means of self-diagnostics.
Condition data and the diagnostic functions help ensure consistent monitoring. Pressure or temperature values that are above or below the specifications are displayed directly in the system. The data also allow conclusions to be drawn about changing process conditions and additional information helps to check the loading.
The scalable analogue output enables the measuring range to be adapted at a ratio of 5:1. In addition, the output signal can be configured specifically for the application, allowing the PSD-4 to be used in a flexible manner.
