DYNISCO PT420A Serisi Eriyik basınç sensörleri

DYNISCO PT420A Series Melt pressure sensors

Brand: Dynisco

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