Pressure Systems has reduced the noise of its KPSI series 340 ASIC-based small-bore submersible level transducers by five times.

By using an improved signal amplifier on the transducer circuit board, the signal output is much quieter, creating fewer errors when retrieving data and increasing data reliability.

The improved series offers custom level ranges up to 230ft (70m) H2O and an accuracy of up to +0.25 per cent FS total error band over the complete operating temperature range of -20C to +60C.

In addition, the series features analogue outputs of 4-20mA, 0-5VDC or mV.

The KPSI series 340 level transducers are ideal for remote environmental water monitoring applications, where small changes in liquid levels are critical, such as surface water, ground water and down-hole monitoring.

Their accuracy makes the KPSI series 340 transducers well suited for use in tank level measuring applications, including above-ground, underground and elevated storage tanks.

With welded 316 SS or titanium construction and an optional chemical-resistant ETFE cable jacket, the KPSI series 340 features a rugged, waterproof design.

Its specially-designed, highly accurate pressure sensor can withstand the harshest environments that contain hostile fluids and gases.

The updated KPSI series 340 includes Pressure Systems’ Superdry long-life vent filter that prevents moisture from entering the vent tube for at least one year without maintenance.

The cable, available in custom lengths, includes Kevlar members to prevent errors due to cable elongation and offers a water-block feature that self-seals the cable in case of an accidental cut.

The KPSI series 340 is CE-compliant to EN 61000-6-4:2001 and EN 61000-6-2:2001 and has an IP68 and a Nema 6P housing protection rating.
