Description

HD22010-3: Product Overview
The EMERSON HD22010-3 is an industrial pressure transmitter designed for precise and reliable pressure measurement in various process applications. This device functions as a critical sensing element in control loops, converting the physical pressure of a liquid or gas into a proportional electrical signal. Installed directly into process piping via a threaded connection (e.g., 1/2″ NPT), its primary role is to provide accurate pressure data to programmable logic controllers (PLCs), distributed control systems (DCS), or other indicators for process monitoring, control, and safety.
The transmitter operates on the principle of sensing pressure with a high-stability sensor (typically a silicon piezoresistive sensor) and converting this measurement into a standardized 4-20 mA two-wire output signal. This signal is proportional to the measured pressure, allowing for long-distance transmission to the control room with high noise immunity. The device is housed in a robust, weatherproof enclosure suitable for harsh industrial environments and features local indication via a digital display or a pointer gauge for easy on-site reading.
