LFT710 Differential Pressure Transmitter uses single crystal silicon sensor chip which adopts German advanced MEMS technology. It has built-in temperature compensation element and extremely high measurement accuracy and long-term stability over a wide range of static pressure and temperature variations. It can measure level, density, pressure of liquid gas and steam. It is widely used in industrial process control, automated manufacturing, aerospace automotive and marine petroleum and petrochemical, electronic power, medical and health and many other fields.
LFT710 can accurately measure differential pressure and convert it into 4-20 mA DC output signal and can be operated locally through three buttons, and remotely operated by a general-purpose communicator, configuration software, and mobile phone APP, to perform display and configuration adjustment without affecting the 4-20 mADC output signal.
High-precision pressure sensor using MEMS monocrystalline silicon.
Fast response time, high stability, measurement accuracy 0.075%FS.
The maximum range ratio can reach 100:1.
Adopt double overload protection technology, strong overload capacity, one-way pressure up to 10MPa.
Provide standard HART bus communication mode, perfect self-diagnosis and remote communication function.
High brightness LCD display with backlight, reversible local display screen.
Convenient in-place current loop calibration function.
In-place zeroing function, in-place zero point, full point setting and adjustment function.
RS-485 and 4~20mA HART two output modes.
