Relative pressure transmitter LFT2080

piezoresistiveceramic4-20 mA

Product overview
The LFT2080 anti-corrosion pressure transmitter integrates a ceramic piezoresistive sensing element with high overload capacity and corrosion-resistant wetted materials (1Cr18Ni9Ti, PVDF, fluoroelastomer, perfluoroether rubber). It uses ASIC digital compensation to deliver stable, repeatable pressure signals for aggressive media and sanitary applications such as water disinfection, chlorine systems, chemical processing, battery equipment, food hygiene and medical installations.

Key applications

• Water treatment and chlorination systems
• Chemical process lines handling strong acids or alkalis
• Battery manufacturing and testing equipment
• Food industry and medical/pharmaceutical pressure monitoring

Features

• Ceramic piezoresistive core compatible with corrosive media
