LXT-330 / LXT-380 – Universal Transmitter and SP-3X Smart

The Model LXT-330 Transmitter is a single or dual channel, universal, multiparameter transmitter designed for the continuous online measurement of pH, ORP, pION, conductivity, resistivity, turbidity, chlorine dioxide (ClO2) or dissolved oxygen in a general purpose industrial environment.

The LXT-330 Transmitter uses the TAI SP-3X series of sensors, which cover a wide range of analytical applications. The same LXT-330 can be used for any of the measurements. There is no longer any need to inventory multiple instrument types. The sensor type, identity, serial number and calibration registers are stored in the sensor’s main memory, facilitated by two-way digital communication between the sensors and the transmitter.

The Model LXT-330 transmitter is available as a loop powered transmitter (standard), or an optional 24 VDC or 100/250 VAC powered transmitter. The loop powered transmitter has a 4-20 mA output or an optional HART® output. The line powered instruments have a 4-20 mA output and MODBUS RTU or HART® and can be ordered with a (3) Alarm Relay option. The relays can be configured as Alarm (set point) relays or Fault relays.

For hazardous area installations, the Model LXT-380 offers a Class I Div 1 (Zone 1) and Class I Div 2 (Zone 2) approved transmitter with NEMA-4 or NEMA-4X ingress protection. Magnetic switches allow for menu navigation and access to transmitter functions.
