It irlCorporates a. unique inductive sensing .and measuring system that provides consistently reliable and stabie performance under all types oi process conditions, coupled with simple lest and calibration procedures and minimum maintenance requirements" The Oeltc!pi K transmiltercomprises two main elemems: a sensor and an electronics module. The sensor converts the differential pressure of the prccess fluid (liquid, gas or vapour) inio proportionate changes of two inductance values from which the electronics module procuces a standard output signal. Seven versions at sensors are avaiiable to suit "he measuring ranges or spans to be used. The electronics module, including all coarse and fine adjustments. process terminations, etc., comprising the top works, is contained within a waterproof housing mounted on the bottom works containing the sensor. process flanges. drainvent vaives, etc. , Protected by onf~ or more 0: the lolfowirrg Patents /tatyn 232i9--A/81 anen 21983,4:8] Europe n. 71581 U SA n 4538465 and 455:9829 Spain rl. 513994 and 534062 ,/apBn P3!ents applied for S.lS.103/E Rev.E
