The new PSD-4 electronic pressure switch (photo, p. 34) enables flexibility in industrial applications because the output signals (PNP/NPN, 4–20 mA or 0–10 V) are freely configurable. The output signal, with a turndown of 5:1, can be scaled to the relevant measuring range. Thus, with just one instrument variant, many specifications can be realized. The PSD-4 features a 9-mm high LED display with 14 segments, which can be rotated continuously through 330 deg. This enables the measured value and status to be read easily in any mounting position. In addition, extensive diagnostic functions inform the user about the instrument status. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
