A head-mounted transmitter is a compact and versatile device designed to convert sensor signals into standardized output for process control and monitoring. Typically mounted directly on sensors, such as pressure, temperature, or level sensors, it facilitates real-time data transmission by converting the sensors analog signal into a digital format or standardized output like 4-20 mA or HART. The transmitter features a robust, weather-resistant housing suitable for harsh environments, and often includes calibration and configuration options to ensure accurate readings. Its design streamlines installation and reduces wiring complexities, making it ideal for industrial applications where reliable data transmission and minimal downtime are crucial.
