The PSD-4 electronic pressure switch from WIKA
EHEDG and 3-A certification of the PSD-4 electronic pressure switch from WIKA makes it suitable for industries with high hygienic requirements. The switch is regarded as the universal solution for industrial automation tasks, in hygienic applications and under harsh conditions.
As a result of an accuracy measurement of less than about 0.5% and minimal long-term drift, the sensor is said to permanently ensure an accurate representation of the process pressure for more than 100-million load cycles.
The pressure switch is available with a digital output signal as well as a switchable and scalable analogue output. In addition, it can also be monitored by means of self-diagnostics.
Condition data and the diagnostic functions allow 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, while 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 flexibly.
