AYSIX LTX01 series 2-wire level transmitters are highly reliable microprocessor based sensors designed to measure tank levels of liquids and certain dry bulk media in metal tanks. LTX01 sensors measure the change in capacitance that occurs as the tank level changes and outputs a standard loop powered 4-20mA signal. After calibration any change in level is recognized and converted to an analog 4-20mA signal. LTX01 sensors use very high frequency and very low amplitude sensing circuitry to greatly minimize the effects of coating on the sensing probe.

The LTX01 includes a standard 4 - 20mA loop powered LTX transmitter housed in a rugged enclosure, a 0.50 inch diameter rigid probe for ranges up to 20 feet and a fitting. Probe material is SS316, supplied bare or PFA jacketed. The LTX01 is designed for tanks which have fitting connections of 3/4 NPT or larger.

LTX01 can be used in many tough industrial applications. This level sensor is shock resistant and very rugged. There are no moving parts. PFA jacketed probe can withstand temperatures of up to 200°C and pressures to 500 psi.
