The Seametrics PT2X-BV is a special version of the PT2X. It is designed to measure barometric and vacuum pressure in reference to absolute pressure, along with temperature and time. It will measure pressure/vacuum from 600 to 1100 millibars.
Pressure measurement is accomplished utilising an extremely rugged and stable 15 PSIA piezo-electric media-isolated pressure element, combined with a 16-bit analog-to-digital converter. This provides extremely accurate and stable pressure input into the microprocessor on the circuit board that measures the pressure, stores the data in non-volatile memory, and communicates the information via a serial communication link (RS485) to the host computer. Temperature measurement is accomplished utilising a temperature sensor chip.
The PT2X-BV is available in two enclosures – either an ABS weather-proof box or a stainless steel tube. The tube version is available with either a solid end cone or an NPT end cone for connecting to piping.The PT2X-BV can be networked with other Seametrics Smart Sensors and can be controlled directly from a single computer.
While most will use the PT2X-BV with Aqua4Plus 2.0 software, it is by no means limited to that software. You can use your own Modbus® RTU or SDI-12 software or logging equipment to read measurements, thus tying into your existing telemetry and control systems.
