WE100 Barometric Pressure Sensor

Features:

• 4-20 mA output: Industry standard signal for easy integration with existing monitoring systems.
• Marine grade cable with strain relief: Built to withstand harsh outdoor environments.

Alarms and Data Logging:

Global Water offers a comprehensive barometric pressure monitoring solution:

• PC320 Barometric Pressure Meter and Controller: Uses the sensor’s output to trigger alarms based on pressure changes.
• GL500 Barometric Pressure Data Logger (Sold Separately): Connects to the PC320’s 4-20mA output to record pressure data over time. This allows for historical analysis and trend identification.

Why Measure Barometric Pressure?

Barometric pressure is a crucial weather parameter because changes in pressure indicate movement of weather fronts. Here’s why it’s important:

• Weather monitoring: Most weather stations rely on barometric pressure sensors for weather forecasting.
• Diverse applications: Barometric pressure sensors are used in various applications like ocean buoys, ships, engine performance checks, airports, and more.
• Water level readings: Pressure sensors help determine surface and groundwater levels. Visit our water level information page for more details (link to water level information page).

Understanding Relative Humidity

Relative humidity refers to the amount of moisture present in the air compared to the maximum amount it can hold at that temperature. Here’s a breakdown:

• Measurement: Expressed as a percentage.
• Relationship with Temperature: Generally, relative humidity is inversely proportional to temperature. So, it’s highest when the air is coolest and vice versa.
• Saturation point: When the air reaches 100% relative humidity, it’s holding all the moisture it can.

Why Measure Relative Humidity?

Humidity significantly impacts our environment. Monitoring it allows for control and mitigation of various effects:

• Human and animal comfort: Improper humidity levels can cause discomfort.
• Material protection: Excessive humidity can damage materials in storage facilities.
• Manufacturing processes: Optimal humidity is crucial for many production processes.
• Construction materials: Humidity can impact the quality of construction materials.
• Many other applications

By measuring and understanding both barometric pressure and relative humidity, you gain valuable insights for various environmental monitoring applications.
