Description Fluke 721 Ex The intrinsic safety dual range precision pressure calibrator RS provides Fluke dual sensor pressure calibrators for classified environmental applications, including gas monitoring transmission measurements in potentially explosive environments. Fluke 721Ex, Equipped with IECEx and ATEX Ex ia IIB T3 Gb (Zone 1), it features two isolated stainless steel pressure sensors with an accuracy of ± 0.025% of full scale, providing static and differential pressure measurements. Each model can be used with a Fluke 720RTD (796-1646) probe (provided separately) for temperature measurement. The Fluke 721Ex can be configured by selecting a 16 psi (1.1 bar) or 36 psi (2.48 bar) low-pressure sensor, combined with one of the following seven high-pressure ranges: 100; 300; 500; 1000; 1500; 3000; 5000 psi (6.9; 20; 24.5; 69; 103.4; 200; 345 bar)。 The backlit display screen can simultaneously display two pressure readings and one temperature reading. Can store up to five commonly used settings. Specially suitable for gas flow calibration (custom transmission) applications, two isolated stainless steel pressure sensors with 0.025% accuracy Pt 100 RTD input are used for temperature measurement (probe provided separately) to measure 4 to 20 mA signals. The internal 24V circuit power supply can supply power to the transmitter during testing, measuring up to 30 V DC. The 24V circuit power supply can be connected to the external 700 series pressure module to expand the pressure measurement range. The large backlit graphic display screen can display up to three inputs simultaneously and store five instrument settings for calling and use. The size (height x width x thickness) is 200 x 110 x 58 mm (7.9 x 4.3 x 2.3 inches), and the net weight is 353.9g (1 lb 3 oz). Note: Optional accessories need to be provided separately, including: transmitter testing hose TTH5K (908-wide x thickness). 3782) and TTH10K (908-3786), Provide a tool free (NTR) connection between the hand pump or pressure transmitter and the standard IEC "fema
