Description

LFT700 can accurately measure the pressure of liquid,gas orsteam,and convert it into 4~20mA output signal.The Transmittercan be operated through three buttons on the device,or by handmanipulator,or configuration software.The display andconfiguration can be adjusted without impacting the 4~20mA outputsignal.It is widely used in pressure measurement in industrial sitessuch as petroleum,chemical,electric power,and hydrology.
