Continuous Level Transmitters

The L95 Series Level Transmitters leverage high performance silicon piezoresistive pressure sensors as the lead sensing element. The transmitter measures the vertical depth of a column of liquid and converts this depth into standard amplified analog signals.

The L95 Series are IP68-rated devices, featuring a fullysealed structure and made from 304 stainless steel. The cable used in these transmitters is anti-oil, waterproof, and electromagnetic effect-shielded.

This device has a fully integrated structure with sensing element and signal conditioning circuit located and sealed in the probe housing. In application, the transmitter is submerged in the measured liquid with no external adjustment or calibration needed.
