Product Overview
The Smart Pressure Transmitter Series HPT is a new-generation microprocessor-based pressure measurement device. It can accurately acquire gauge pressure, absolute pressure, or differential pressure signals from media such as gas, liquid, and steam, and convert them into standard electrical or digital output signals. It also supports data communication, remote calibration, and fault diagnosis.The product is widely used in petrochemical, metallurgy and power industries, water treatment, intelligent manufacturing, and other sectors, providing reliable data support for real-time monitoring, quality control, and energy optimization in industrial processes. The HPT series is a high-precision industrial pressure transmitter with excellent accuracy and stability (up to ±0.075% FS). It supports multiple communication protocols (4–20mA HART, RS485 Modbus), making it suitable for integration into intelligent automation control systems. With a durable stainless-steel housing, wide operating temperature range (-40°C to 85°C), and IP67 protection rating, the HPT ensures accurate and reliable measurement of various media (gas, liquid, oil) in critical applications across oil & gas, chemical, energy, and industrial manufacturing sectors.
