Model LXT-380

Universal Transmitter

Description

LXT380 Explosion Proof

The Model LXT380 transmitter is a single or dual channel, intelligent, multi-parameter designed for the online continuous measurement of pH, ORP, Specific Ion (pION), dissolved oxygen, free chlorine, total chlorine, conductivity and resistivity. The Model LXT380 Tramsitter digitally communicates with the SP3X digital sensor, automatically configuring the trasmitter's menues and display screens to the measured parameter. The LXT380 tramsitter can be Loop powered or 4-wired DC powered. The standard configuration has a 4-20 mA and a serial communication port with MODBUS RTU output. Alarm relays option is only available on 4-wired DC powered transmitters. LXT380 Transmitter loop is available in FM, ATEX and IECEx certifications.
