Introduction

The LL-V liquid level sensor is designed for vertical insertion into a tank or well for complete immersion in the fluid. The fully welded stainless steel sensor body and diaphragm are corrosion resistant to most fluids.

Connections consist of a waterproof cable with a 1/2-14 NPT threaded interface that allows attachment to a variety of tubing or flexible conduit. The four conductor cable has an atmospheric vent tube connected to a fully welded chamber inside the sensor to provide an atmospheric zero reference.

Pressure ranges are from 50 mbar to 3.5 Bar (50 cm to 35m water column). They use 350 ohm strain gauges mounted in full bridge. The total accuracy is 0.10%.

Setup

Configuration options include:

Extended operating temperature range
Amplified output (5 Vdc or 4 mA to 20 mA)
Most amplified models have internal shunt calibration circuits as a standard feature to facilitate sensor configuration on the acquisition system.
