Absolute pressure transducer PT420A

membraneanalogmelt

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. PERFORMANCE CHARACTERISTICS Output: 3.33 mV/V +/- 2.0% Input Voltage: 10 Vdc recommended, 12 Vdc maximum Repeatability: +/- 0.1%FSO, +/- 0.2% FSO for 500, 750, 1,000 psi ranges Configuration: Four-arm bonded foil Wheatstone bridge strain gage Bridge Resistance: Input: 345 Ohms minimum, Output: 350 Ohms +/- 10% Over Pressure: 2 X FSO or 35,000 psi whichever is less Zero Balance: +/- 5% FSO Internal Shunt Calibration (R-Cal): 80% FSO +/- 0.5% Insulation Resistance: 1000 megohms @ 50 Vdc TEMPERATURE & MECHANICAL CHARACTERISTICS Sensitivity Shift Due to Temperature Change: +/- 0.005% FS/oF max (+/- 0.01% FS/oC max) Mounting Torque: 500 inch/lbs. maximum Standard Wetted Parts: Dymax® coated 15-5 PH SST
