WIKA A-10 Industrial Pressure Transmitter / Digital Gauge
Model: A-10
The WIKA A-10 is an industrial pressure transmitter/digital gauge using a ceramic capacitive sensor with ±0.5% FS accuracy. It covers 0–40 bar with a 4–20 mA output signal plus local digital display — connecting directly to PLC/SCADA systems. Better repeatability than Bourdon gauges and vibration-resistant for tough industrial environments, with IP67 protection. Popular in Thai process industries as a step up from mechanical gauges where digital accuracy and signal output are needed.

Frequently Asked Questions
How is it better than a Bourdon gauge in practice?+
Better accuracy (±0.5% vs ±1% FS), better vibration resistance, and direct 4–20 mA output to SCADA — but 5–10× the cost and requires a power supply.
How often should the WIKA A-10 be calibrated?+
Every 1–2 years for general industrial use. Safety-critical or custody-transfer applications may require 6-month intervals with a traceable calibration certificate.
