Level Transducer LTR6000

The LTR6000 is a resistive chain level sensor, used for the measurement of liquid level in open or closed tanks. It operates on the principle of communicating vessels, where the level in the measuring column is continuously the same as the level in the application vessel.

The LTR6000 is mounted externally on the measuring column which contains a magnetic float, following the liquid level changes. Having an incorporated array of closely spaced magnetic switches, the LTR6000 senses the position of the magnet, providing a continuous, linear analog 4-20mA output signal which is proportional to the level of the liquid.

It is composed of a stainless steel square tube, which incorporates the sensor chain and an IP66 polycarbonate enclosure on top of it, containing the transmitter for the 4-20mA output signal with the necessary connection terminal block.

The standard version is designed for 1m maximum level height. However, in applications where measurement of different level height is needed, customization options are available.
