Smart card is essentially a credit-card sized computer. Embedded in the card is a microprocessor with memory that can be read and more importantly can store a significant amount of information. Counterfeiting is extremely difficult because the chip is buried in plastic. In addition, the chip can be programmed to generate its own password and codes, including sophisticated encryption functions. There are three types of smart cards such as memory-only, memory circuits with some hard-wired security logic and full-fledged microcomputers. Although a smart card looks similar to a standard credit card, it differs by having five to eight metallic contacts displayed on its surface.
Smart Pressure Transmitters are a complete line of differential, gage and absolute wide range pressure transmitters. It includes flush diaphragm & sanitary flange for liquid level measurement, hydrostatic tank gauging and wetted parts in several materials for suiting process requirements.
Smart RF level transmitter is a loop-powered, liquid level transmitter. As the level varies in a tank, the amount of capacitance developed between the probe and the tank wall changes. This capacitance is converted to a level measurement. It is used in liquids or slurries and hydrocarbons to water-based media applications.
Smart Temperature Transmitters are microprocessor-based instruments that accept inputs from a wide variety of sensors. Smart transmitters reduce maintenance trips to the field through advanced diagnostics.
Smart Transmitter is a microprocessor-based device with diagnostics capability and two-way communication using digital field protocols. These smart transmitters are available with different protocols. Smart transmitter calculates performance parameters such as voltage and current.
