OPTIBAR LC 1010  Pressure level transmitter

The OPTIBAR LC 1010 is a submersible level probe for water and wastewater, environmental engineering and OEM applications. It is particularly suitable for continuous hydrostatic level measurement in water wells, rainwater retention and overflow basins or tanks. The level transmitter features a robust stainless steel housing and a high overload-resistant ceramic diaphragm for long-term operation. The diaphragm is flush mounted for safe and easy cleaning on site.

The level probe comes with pre-configured measuring ranges from 100 mbar / 1.5 psi to up to 10 bar / 150 psi. Customer-specific ranges are available on request. Its corrosion-resistant TPE cable is approved for use in potable water applications. The OPTIBAR LC 1010 features a 4…20 mA output and optional HART®7 for convenient configuration. The level probe can also be provided with an integrated Pt100 temperature sensor.
