Smar was founded on April,1st 1974 by Mr. Mauro Sponchiado and Mr. Jose Martinussi who took the initials of their names to form the company's name. First area of business was service steam turbines in sugar refineries nearby Sertãozinho, Brazil. Smar added in-house electronics expertise when electronic speed regulators were introduced for steam turbines in 1978. It soon developed electronic controls for cane cutters and crushers as well.
Smart Pressure Transmitter Series
The LD301 is a smart pressure transmitter for differential, absolute, gauge, level and flow measurements. It is based on a field-proven capacitive sensor that provides reliable operation and high performance. The digital technology used in the LD301 enables the choice of several types of transfer functions, an easy interface between the field and the control room and several interesting features that considerably reduce the installation,operation and maintenance costs.The LD301, besides the normal functions
Smart Concentration/Density Transmitter Series
The DT301 Intelligent Concentration/ Density Transmitter is an instrument developed for the continuous, online measurement of liquid concentration and density, directly in the industrial process. Its pioneer technology consists of a capacitive type differential pressure transmitter coupled to a pair of pressure repeaters immersed in the process.
Smart Temperature Transmetitter Series
The Smar TT301 is a powerful and extremely versatile programmable temperature transmitter, which can be used with practically all relevant temperature sensors as well as with load cells, resistance position indicators, etc. The TT301 transmitter is suitable for direct field installation, being weather and explosion proof as well as intrinsically safe.
Smart Valve Positioner
The FY301 microprocessor based positioner provides fast and accurate positioning of diaphragm or cylinder actuators. The FY301 produces a pressure output as required to position a control valve according to a 4 to 20 mA input signal supplied by a controller. The FY301 is part of SMAR's complete 301 series of smart devices.
