The HPM311 Air Differential Pressure Transmitter is constructed with a CNC-machined aluminum alloy housing, providing both durability and lightweight design. It employs a highly accurate and stable sensing element that effectively converts the pressure signals from the measured medium into either a 4-20 mA DC output or a standard voltage signal. This transformation is facilitated by a reliable and well-designed electrical circuit.

Additionally, the transmitter is equipped with a convenient field display that enhances operational configuration capabilities, allowing users to easily adjust range settings and perform pressure value (PV) resets as needed.

With a premium sensor at its core, combined with advanced packaging technology and meticulous assembly processes, the HPM311 guarantees outstanding quality and performance. This device is ideal for a variety of applications, ensuring precise measurements and reliable operation in diverse environments.
