Products 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.

STANDARD  SPECIFICATIONS

Pressure range is calibrated based on the standard zero poir stainless steel 316L diaphragm,filled liquid is silicone oil.
