T7N Series Valcom pressure transmitters

T7N Series

These transmitters allow the measurement of pressure, vacuum and level in industrial, marine and off-shore.

Configurations and adjustments can be made locally by means of push buttons and display or remotely using HART® protocol compatible communicators.

The transmitters are intended for direct mounting on pipe or tank. For remote sensor version and when remote seal and capillary are supplied, a bracket for wall or for 2” stand pipe mounting is also supplied.

APPLICATION FIELDS

• Pressure, level and vacuum measurement;
• Installation on chemical, Oil & Gas, pharmaceutical, alimentary, marine plants etc;
• Installation in areas with persistence of potentially explosive mixtures.
