Overview
The WIKA S-20 is a general-purpose pressure transmitter for machine builders, hydraulics, pneumatics and process utilities, configurable in thousands of combinations of range, accuracy, output, process connection and electrical connection. Accuracy is ≤0.25 % of span (≤0.125 % optional) with a thin-film sensor and welded 316L wetted parts, no internal seal, so it handles oils, water, gases and mild chemicals. Output options cover 4–20 mA, 0–10 V, 0–5 V and ratiometric, with M12, DIN A plug or cable; the 10 bar G1/2B 4–20 mA example is the most common utility configuration. For panel-mount monitoring or PLC inputs it is often the most economical transmitter with full traceability and a WIKA calibration certificate.

Frequently asked questions
What is the difference between the S-20 and the A-10?
The A-10 is WIKA's economy transmitter with 0.5 % accuracy and fewer options, aimed at OEM volume. The S-20 adds 0.25 % (or 0.125 %) accuracy, more ranges, outputs and connections, and better temperature behaviour. Both are 316L and fully welded.
Can I get a custom range or scaling?
Yes. The S-20 can be ordered with non-standard ranges and with 4–20 mA scaled to a specific span, and a calibration certificate is supplied with every unit on request.
Is the S-20 available from stock, and what is the lead time?
Common ranges and G1/2B / M12 configurations are typically 1–2 weeks; special versions 3–4 weeks. We confirm with the quotation.
