Seametrics PT12-BV Barometric/Vacuum Sensor

The Seametrics PT12-BV comes as a weatherproof stand-alone box or with an automatic compensation wiring option. The PT12-BV measures pressure, temperature, and supply voltage.

The weatherproof box is an ideal barometric reference for absolute pressure sensors. This version features both an SDI-12 interface and a Modbus® RTU interface that makes the product easy to connect to recorders and operates on low power. This makes it a preferred choice for many environmental professionals with existing SDI-12 or Modbus® RTU systems.

With the Compensation Wiring Option, the PT12-BV automatically provides barometric compensation for a single attached absolute PT12 submersible pressure sensor. No post processing of data. No need to use a vented cable or worry about maintaining desiccant tubes. This version features an SDI-12 communication interface, making it ideal for many existing environmental systems.
