DMP305X-DS

Differential pressure transmitter measures pressure difference between two sides, Device through high pressure side (HP) And low pressure side (LP) Two pressure ports connect to different measuring points of the system 。When gas or liquid medium acts on both sides, Generated pressure difference (ΔP) Drives internal sensing element (Such as metal diaphragm ) Generates mechanical deformation 。Deformation converted to electrical signal by capacitance effect or strain gauge principle, Amplified by signal conditioning circuit, Linearization compensation and temperature correction processing, Finally outputs industrial standard 4-20mA Analog or digital signal (如HART Protocol ) 。

Standard type

LEEG monocrystalline silicon pressure transmitter uses monocrystalline silicon pressure sensor, monocrystalline silicon pressure sensor located at top of metal body, away from medium contact surface, mechanical and thermal isolation, high-strength electrical insulation between glass-sealed sensor leads and metal body, improved electronics flexibility and transient voltage protection, handles complex chemical conditions and mechanical loads, strong electromagnetic interference resistance, for pressure in demanding process industry environments, level or flow measurement applications 。
