Which gauge is designed to provide a digital display and electronic signal rather than a purely mechanical indication?

• A. Mechanical gauge
• B. Digital gauge
• C. Pressure gauge
• D. Optical gauge

Answer: (B)

Digital gauges are built to provide a digital readout and an electronic signal. They use a sensing element to convert pressure into an electrical signal, which is then displayed on a digital display and can be sent to control systems or SCADA for remote monitoring, data logging, and alarms. This contrasts with mechanical gauges, which rely on a Bourdon tube and a moving pointer to indicate pressure without any electronic output. Optical gauges may show readings through optics but aren’t defined by a digital electronic signal, and the general term pressure gauge can refer to either mechanical or digital devices. The key is the combination of a digital display and an electronic signal, which is unique to the digital gauge.
