The Model 765 Programmable Transducer Conditioning Amplifier (PTCA) features full remote or front-panel manual control of virtually every operating function including: several excitation, signal conditioning, and calibration modes; amplifier input, output, filter and gain modes; and automatic and incremental zero and bridge balance modes. Ideal for computer controlled data acquisition systems, the Model 765 PTCA can be used with almost any transducer from strain gages, RTDs and potentiometers to thermocouples, accelerometers, and pressure gages. Its precision amplifier can also be used for most low-level or high-level signal sources.
Each Model 765 PTCA is self contained with individual isolated power supply. It is a mechanically rugged modular unit with all external metal surfaces at safety ground. Each unit is provided with a front-panel plug-in Configuration Card with a handle that doubles as a channel I.D. holder and with front-panel monitor jacks for amplifier input and excitation output.
All user-configurable components, including bridge completion resisters, shunt calibration resistors, balance limit resistor, bridge calibration configuration switches, and a plug jumper selection for voltage or current monitoring, are contained on the Configuration Card.
Each Model 765 PTCA has an on-board microprocessor, with battery backup, to handle all control functions whether received via remote program command or via its front-panel manual control.
