Products Siensor D115

The Siensor D115 liquid level sensor is an intelligent device designed for high-accuracy measurement of fuel level in the tanks of vehicles, including special purpose machinery and stationary reservoirs (diesel-generators, boiler plants, oil storages, etc.). Siensor D115 measures fuel level transmits data to the terminal via RS-232 or RS-485 interface, which displays it in litres or percent. The length of Siensor's D115 is 1500 mm.

Siensor D115 has a long service life. The manufacturer's limited warranty is valid for five years from date of purchase. Siensor D115 features reliable interference protection, high-accuracy data transmission and maximum measurement resolution. Complete galvanic isolation provides high level of power supply circuit protection. Data processing algorithms enable high-accuracy detection of fuel filling, draining and consumption.

Siensor D115 is compatible with most liquid types. On request, it is possible to order the product with the length of a measuring part different from the original one.
