The product is facilitate, voltage of 4-20mA, pressure transmitter. Even in bad condition ,it still work well.PT299 is fully welded, which has a big diaphragm and a flange gasket, easy to install. PT299 is stetted 1 class, 1 part ,A,B,C&D group’s explosion-proof has been certificated , which is equipped conduit.PT299 has ATEX/nature safety‖ 1 Gooa Eex ia‖C,0 and 1 part’s certification. ATEX/safety mode can provide through a equipped duct or a seal 6 needles Meredith Nadu connector. PT299 also has a creative new PT299 system- a advanced biasing linear consult rule part which caused by material and machining , which makes probes accurately measuring pressure and temperature . temperature sensor is equipped J,K,E or PT100 Bo resistance available.
