Product Overview:
HPM311 Air Differential Pressure Transmitter adopts CNC integrated aluminium alloy shell. The transmitter sensor with high accurate and high stable sensitive core to transform the pressure signal of measured medium to 4-20mADC signal or standard voltage signal through high reliable enlarged electric circuit. It is with the field display and configuration operation functions. The range is adjustable and the PV can be reset.This product with the high-quality sensor, superb packaging technology and perfect assembly process guarantees the excellent quality and functions.
Features:
·Measure differential pressure of micro air
·Field display and configuration operation
·Hard and sealed aluminium alloy shell
·Short-circuit protection and reverse polarity protection
·All range temperature compensation
·Strong anti-jamming and long-term stability
