Description

Applied Measurements barometric pressure sensors Pa600B measure absolute pressure and are designed for the measurement of atmospheric pressure fluctuations. Applied Measurements barometric pressure sensors are ideal for use in weather applications, including weather forecasting, where pressure changes in the atmosphere need to be monitored.

Applications include:

  • Weather Applications
  • Weather Forecasting
  • Atmospheric Changes
  • Altitude Compensation
  • Altimeters
  • Remote Weather Stations

Constructed from stainless steel, and available with a variety of process connections, these barometric pressure sensors are designed to withstand humidity, precipitation, and water ingress.

As standard our barometric pressure sensors Pa600B come with: Viton O-ring, 303 stainless steel case, 316L stainless steel sensing diaphragm and a G¼ inch male process connection. Alternate case, O-ring material and process connections are available including G¼” female and ¼” NPT male.

The Pa600B barometric pressure sensors series provides a wide choice of electrical outputs from its ASIC-based amplifier circuit, these include 4-20mA, 0-5Vdc, 0-10Vdc, 10mV/V, as well as a ratiometric 0.5-4.5Vdc (10% to 90% of supply voltage) signal that requires a 5Vdc (2.7 – 5.5Vdc acceptable) to suit most dataloggers.

Applied Measurements has a range of precise instrumentation that can be used with our barometric pressure sensors to give you a complete, calibrated pressure measurement system.
