28 B3512 SERIES OF TRANSDUCERS MODULES WITH AMPLIFIERS FOR SIGNAL CONDITIONING Here is a series of small size boards, each one including a specific type of transducer and its interface circuit. The interface/conditioning amplifier supplies power to the transducer in the appropriate form (AC, DC, in direct or bridge configuration). It amplifies and linearizes also the transducer output, to match a standard measure range of 0-10V. The following transducers modules are available: B3512-A NTC temperature sensor (0 C to 100 C) B3512-B - PTC temperature sensor (0 C to 100 C) B3512-C Pressure sensor (0 to 0,5 PSI) B3512-D Light sensor (photo-resistor) B3512-E Light sensor (photo-transistor) All the modules are realized on a 100 x 80mm PCB, with the components in view and a clear silk-screen printing. The connection to the inputs/outputs of the module is done by terminals or 2mm female jacks for easy use. Each module is supplied complete of accessories and manual for operation and calibration details. All the modules are supplied by a stabilized source of +15V/-15V, like the B4192-B. Some modules do not need a negative power supply.
