The PT420 Series transducer is a ±0.25% sensor ideal for melt pressure applications requiring high accuracy, simple installation, repeatability and reliability. The PT420 transducers provide the industry standard 3.33 mV/V signal designed to work with most pressure indicators. The MPT420 comes equipped with an eight pin Bendix connector. Optional thermocouple or RTD configurations are available to provide melt temperature. The PT420 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.
