Explanation

PT420A Series

The PT420A Series transducer is a +/- 0.25% sensor ideal for melt pressure applications requiring high accuracy, simple installation, repeatability and reliability. The PT420A transducers provide the industry standard 3.33 mV/V signal designed to work with most pressure indicators. The PT420A comes equipped with an eight pin Bendix connector. Optional thermocouple or RTD configurations are available to provide melt temperature. The PT420A features a 1/2-20 UNF thread for installation in standard transducer mounting holes and can be supplied with a variety of other electrical connections if desired.

The PT420A Series includes models PT420A, PT422A, TPT420A, TPT432A and TPT422A.
