Submersible level transmitters

Instrumentation · Level

Nuova Fima ST LV submersible level transmitters measure the level of liquids in wells, reservoirs and tanks from the hydrostatic pressure of the liquid column and convert it into a two-wire 4-20 mA signal. They are immersed directly in the fluid, suspended from their own cable, and their silicone-oil-filled piezoresistive sensor, housed in a compact 27 mm diameter AISI 316L case, makes them suitable for water treatment and for viscous or sediment-laden media. They cover gauge ranges from 0…0.1 to 0…25 bar (approximately 1 to 255 m of water column), with accuracy ≤ ±0.35% of range to IEC 61298-2, non-linearity ≤ ±0.175%, long-term drift ≤ 0.2% and response time below 4 ms. Allowed fluid temperature is -10 to +60 °C, supply is 10 to 30 V and the electrical connection is a vented polyurethane cable, with Viton gasket. They comply with the EMC 2014/30/EU and PED 2014/68/EU Directives and the EN 61326 electromagnetic compatibility standard. At Tecnovent we help you choose the range and cable length for your tank height.
