High Precision 3051SDP Differential Pressure Transmitter
The FD3051DP differential pressure transmitter developed by FRD SENSOR is a new-generation industrial pressure measuring device based on advanced monocrystalline silicon sensor technology. It features high precision, strong stability and excellent anti-interference performance. This transmitter can accurately measure tiny and large differential pressure changes in various industrial pipelines and closed containers. Equipped with standard 4-20mA and HART dual output, it supports remote monitoring, parameter adjustment and real-time data transmission. With full industrial-grade protection and explosion-proof certification, it can work stably in high temperature, low temperature, humid, dusty and flammable and explosive harsh environments, widely used in process industries worldwide.
- Adopts imported monocrystalline silicon pressure sensor, with high accuracy of ±0.075%FS and ultra-low drift.
- Supports 4~20mA analog signal and HART digital communication, easy for system connection and remote maintenance.
- Super wide measuring range, suitable for micro differential pressure and heavy differential pressure working conditions.
- IP68 full waterproof and dustproof grade, adapt to outdoor field and underwater working environment.
