The EA14F is an intelligent multifunction level instrument that measures and displays level when connected to an NC54 or NC56 Capacitive Level Transmitter. The measured value can (optionally) be transmitted to the EA14F as a standardised 2-wire or 3-wire electrical signal. Its programmable limit detection functions enables it also to act as an accurate and versatile level switch. The electronic module converts the analogue signal from the level transmitter and then digitally processes these values. The microcontroller based EA14F has a high degree of user programmability, making it a truly versatile device. The electronic module computes the level, controls the local digital display and (optionally) produces a new analogue signal output. The measurements can be filtered, scaled, inverted or linearised through a user-defined look-up table. The EA14F can be programmed to display the value of either input or converted output signal. The input signal can be converted using its freely-programmable look-up table function for linearisation or conversion to derived units of measurement, e.g., %, m³, Kg, etc. The external level transmitter is connected to and energized by the electronic module through a flexible signal cable terminated by a plug-in connector.
