About LEFOO LEFOO Pressure Sensing and Control Technology LEFOO is committed to supply high quality professional mechanical structure controls, electronic digital sensing controls, micro pumps, which can be widely used in environmental control, mechanical equipment, intelligent equipment, home appliances, medical, power, Internet of things, data center, water treatment, water purification, and other industrial fields. LFT6800 Digital Display Pressure Transmitter adopts a high-performance ceramic or oil filled sensor, with advanced circuit processing and temperature compensation technology, converting pressure changes into linear current, voltage or RS485 signal. The Transmitter is designed in small size, easy installation. Anti-corrosion stainless steel shell protects the transmitter from corrosion, capable for measuring the pressure of gas and oil that compatible with the contacting material.
