The Series 7116B Spirahelic® Pressure Indicating Transmitter simultaneously provides local indication on a large, easily read 4-1/2" (114 mm) analog scale while also converting that pressure into a standard two, three, or four-wire, 4-20 mA signal. The gage employs a unique triple helix Bourdon tube for precision measurement of compatible gases and liquids accurately within ± 0.5% of full scale. The 316 stainless steel connection features a convenient 1/4" female NPT internal and 1/2" male NPT external pressure connection also includes an integral filter plug to keep dirt out.
