The PSQA pressure transducer is a combination of a model PSQ thin-film pressure sensor and a circuit-powered programmable indicator. A five-digit LCD display allows visualization of the measured pressure in the range of -9999 to 9999 with programmable limits for scaling purposes using different pressure units. The PSQA is also equipped with a programmable alarm control relay output, which can also be used for two-position control of various actuators. Input and display correspondence, decimal place, readout correction and other parameters are fully programmable via front panel keypad. Thanks to its excellent price-performance ratio, as well as its compact design and the possibility of a serial interface, PSQA is widely applicable for solving low-budget engineering tasks of pressure measurement and control.
