Bailey & Mackey Transducers Type 481

Description

This series of miniature Pressure Transducers have a piezo-resistive sensor and a unique conductive seal
that eliminates internal wire bonding thus enhancing reliability. Zero and full scale adjusters are
provided under the top cover. They are ideal for use in areas requiring exact pressure measurement, low
hysteresis and long term stability. For all applications where air, oil or water are to be monitored.
