With an accuracy of ±0.7 mm the servo gauge 770STG measures storage tank levels. Due to its isolated touch-screen user interface it can eliminate the need for hot working permits. In chemical, petrochemical, oil and gas industries it operates as a level only gauge, or a level, density and product interface gauge. Data may be transmitted from pressure and temperature sensors. A 25 bar version allows high pressure working. Hart or Rackbus interfaces are available. When used with the 4200 multi-function controller other plant communications schemes will be given. Options include 4 to 20 mA loops, Modbus, and Whessoe Varec protocols. Certifica-tions include Cenelec EEx d IIB T6 PTB Zone 0, and meet NMI and PTB standards for custody transfer applications.
