• Caged 249 series sensors come standard with a liquid damping orifice in the lower equalizing connection that helps stability where vessel capacitance is small and permits narrower proportional valve settings.
• Displacer reaction to small specific gravity changes allows these instruments to be used for density applications and in other applications where a response to low levels of input signal change is required.
• Few moving parts are used. A knife-edged driver bearing in the sensor helps to provide low-friction operation. Sensors are available in ratings up to CL2500.
• Caged sensors are available in a variety of orientations and connection styles, and all sensors can be either right or left hand mounted.
• The torque tube can be replaced without removing the torque tube arm.

• Intuitive Local Operator Interface with four push buttons and LCD enable setup and calibrate the device without external tool.
• Internal temperature sensors enable consistent performance of the digital level controller, despite ambient temperature changes.
• NE107 alerts allow device specific diagnostics to be summarized to simple status signals that help plant operators to take action as required on the process.
• Accurate, high-gain analog-to-digital conversion enables measurement of small changes in the process variable. This allows usage in dificult liquid level, interface, or density application.
• Dynamic temperature compensation for use in process with varying density resulted by temperature change to maintain process variable accuracy.

• For quick analog transmitter replacement, the instrument may be configured with default sensor data, zero level offset, differential process SG, and zero/span procedure only.
• Accurate, high-gain analog-to-digital conversion enables measurement of small changes in the process variable. This allows for use in difficult liquid level, interface, or density applications.
• An internal temperature sensor enables consistent performance of the digital level controller, despite ambient temperature changes.
• Mechanical safeguards designed into the digital level controller help to withstand physical abuse often incurred during installation or in transport, without compromising performance.
• Field wiring connections are in a compartment separated from the electronics. This protects the electronics from any moisture brought into the housing by the field wiring.
• Includes self-diagnostics that detect an error that may render the process variable measurement inaccurate.
