LFT700 pressure transmitter is used to measure the liquid leveldensity and pressure of liquid, gas or steam, then convert it to 4~20mA DC output signal. The transmitter can be operated locally with three buttons, or remotely operated by a universal hand operator, configuration software, and mobile phone APP. It can perform display and configuration adjustments without affecting the output signal of 4~20mA DC.
High-precision pressure sensor using MEMS monocrystalline silicon.
Fast response time, high stability, measurement accuracy 0.075%FS.
Turndown ratio up to 100:1.
Provide standard HART bus communication mode, perfect self-diagnosis and remote communication function.
High brightness LCD display with backlight, reversible in-place display screen.
In-place zeroing function, in-place zero point, fullpoint setting and adjustment function.
Convenient in-place current loop calibration function.
Various types of connection.
RS-485 and 4~20mA HART output mode.
