The Triflex LNI 200 is designed to measure the level on the outside of a non-metallic tank without physical contact with the product. The LNI 200 incorporates the unique FTC technology (Field Time Control). This is a new innovative technology where an electric field is generated between a transmitting electrode and multiple receiving electrodes. The cycle time of the FTC level sensor changes as soon as a product intervenes this electric field. Multiple advanced receiver circuits are embedded to detect the level of low dielectric material, like bulk solid material or dry food products. The Triflex LNI 200 transmitter does not require moving parts or product contact that may be subject to failure situations. Applications with a sensor with FTC Technology provide a more reliable and cost effective solution.
