Submersible Level Transmitters


The SLT20X series of submersible level transmitters are suitable for hydrostatic depth measurement of non-aggressive liquids (without solid impurities) in non pressurised vessels.

They find applications in chemical, food processing and pharmaceutical industries, reservoirs, borewells, sumps & tanks, where the instantaneous level of the liquid is required to be known. An SLT transmitter outputs an analog 4 to 20 mA signal which can be used by measuring and control devices.

The transmitter’s parameters, including zero (level corresponding to 4 mA) and span (level corresponding to 20 mA), can be adjusted using the PC based utility available..

The ease of mounting an SLT20X transmitter makes it ideally suited for use in tanks of all shapes and sizes and in a wide range of industrial applications from water to demanding chemical processes.
