PT 420 | 422 | TPT 432
The PT420 Series sensors are an ± 0.50% accuracy sensor that is ideal for sensing melt pressure that requires high accuracy, ease of installation, repeatability and reliability. PT420 sensors provide a 3.33 mV/V output signal that is designed to work with most pressure indicators.
The PT420 is equipped with an 8-pin Bendix connector. Optional thermocouples or RTD configurations are also available for sensing melt temperature and pressure at a single point. The PT420 is UNF 1/2-20 threaded for mounting in standard mounting holes and can be supplied with a number of other electrical connections.
