- Model LTX02 Series - Heavy Duty Concentric Tube Type Continuous Capacitance Level Transmitter



AYSIX LTX02 series 2-wire level transmitters are esentially LTX01 transmitters assembled with a concetric tube. As such LTX02 sensors can measure tank levels of liquids in metalic as well as non-metalic tanks. All other performance specifications are indentical to LTX01 sensors. Level measurement of water based liquids in non-metalic tanks, using a teflon coated probe is an ideal application for the LTX02. To obtain a linear output in an irregularly shaped tank, such as a cone, use a concentric tube LTX02. For oils and mineral based liquids in non-metalic and metalic tanks use LTX02 with a bare SS316 probe. Make sure that the liquids are compatible with SS316 and PFA Teflon materials.

The LTX02 includes a standard 4 - 20mA loop powered LTX transmitter,a rugged customer selected enclosure, a rigid bare SS316 or Teflon coated probe, concentric tube for ranges of up to 20 feet and a fitting. The LTX02 is designed for tanks which have fitting connections of 3/4 ” NPT or larger.
