IHTM produces pressure transmitters, temperature transmitters, level transmitters and transmitters of differences pressure. All transmitters consist of measuring chamber, transitional part and electronic boxes. The paper analyzed the development of measuring chamber, the procedures of welding elements and the way of control chambers welded joints. Creating and control welding circuit defines the successful implementation of measuring chamber.IHTM proizvodi transmitere pritiska, temperature, nivoa i diferencije pritiska. Svi ovi transmiteri se sastoje od merene komore, prelaznog dela i kutije elektronike. U radu je najpre ukratko analizirana konstrukcija transmitera pritiska. Zatim je prikazana tehnologija zavarivanja njegovih sastavnih elemenata pomoću plazme i načini kontrole zavarenog spoja, da bi se potvrdila uspešnost formiranja merne komore
