Dwyer Series 7116B Series 7116B Spirahelic® Pressure Indicating Transmitter

Dimensional Enlargement


The Series 7116B Spirahelic® Pressure Indicating Transmitter simultaneously provides local indication on a large, easily read 4 ½" 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 block features convenient dual ¼" NPT female and ½" NPT male pressure connections and the pressure block includes integral filter plug to keep dirt out.
