Description: The Model 764 Differential Pressure Transmitter provides a 4-20 mA or 10- 50 mA proportional-to-differential pressure signal for transmission to remote receiving, control, or readout devices. The electronic components of the Model 764 transmitter are housed in a pressure-sealed enclosure. The instruments are designed to operate beyond their normal operating environmental specifications for a limited period of time under such adverse conditions as may be encountered within the containment of a nuclear power plant under accident and post-accident conditions. These adverse environments include severe changes in ambient pressure, temperature and humidity, seismic events, and radiation exposure. The Model 764 transmitter combines a differential pressure unit (DPU) with an electronic circuit. The 4-20 mA or 10-50 mA output is compatible with a wide range of electronic receiving, control, and readout equipment. The instrument utilizes electronic circuits and a molecular-bonded strain gage sensing cantilever beam, actuated directly by the bellows travel within the DPU. Differential Pressure Unit (DPU) The mechanical actuating device for the Model 764 transmitter is a dual bellows assembly enclosed by a set of two pressure housings. The dual bellows assembly (Figure 2.1, page 7) consists of two internally-connected bellows, a center block, overrange valves, a temperature compensator, a strain gage assembly, and range springs. The internal volume of the bellows and center block is completely filled with a clean, non-corrosive, non-conductive liquid with a low freezing point and sealed. The motion-sensing cantilever beam is also sealed within this environment. Electronic Transmitter The electronic transmitter supplies either a 4-20 mA or 10-50 mA direct current output signal that is proportional to the differential pressure sensed by the DPU. The output signal is transmitted over a two-wire transmission line to remote receiving devices. Power Supply A regulated direct current (DC) power supply is required to operate the transmitting loop.
