Model LXT-330​​​

Universal Transmitter



 Description

The Model LXT-330 Transmitter is a single or dual channel, universal, multi-parameter 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 uses the SP-3X series of sensors, which cover a wide range of analytical applications. The same LXT-330 unit can be used for any of the measurements, i.e. plug a conductivity sensor into the LXT-330 pH transmitter and it will automatically reconfigure into a conductivity transmitter.


Sensor’s Main Memory

The sensor type, identity, serial number and  calibration registers are stored in the sensors main memory, facilitated by two way di​gital communication between the sensors and the transmitter. A converter option is available to allow the use of non-digital sensors. The LXT-330 allows for single or dual sensors per transmitter.


Three Graphic Styles

The LXT-330 features a large, easily viewed LCD display with switchable screens including the main numeric screens, graphical screens showing a trending chart in a selectable format and diagnostic data for trouble shooting. The three graphical styles that are available are Trend Line, Bar Graph or Gauge. Menu navigation is accomplished using membrane switch buttons with soft keys displaying the function associated with the button. Pressing any of the buttons twice within 2 seconds activates the soft key function menus. The primary menu selections are the Calibration, Configuration, Info and Simulate Menus.


Loop-Powered vs Line-Powered

The Model LXT-330 transmitter is available as a loop-powered transmitter (standard), or an optional 24 VDC or 100/250 VAC powered transmitter. Loop-powered instruments have black lettering on a grey background, while non-loop powered instruments have blue lettering on a white background when the LED back-light is on. 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 TRU 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.​
