Techniques

Chapter 1: Techniques

Cerabar Pressure Measurement Techniques

The Cerabar family of pressure transmitters utilizes different measurement techniques to cater to diverse applications within environmental and water treatment. The key techniques are:

1. Ceramic Capacitive:

• Principle: This technique measures the change in capacitance between a ceramic sensor element and a reference electrode. The pressure applied to the sensor element alters the capacitance, which is then converted into a pressure reading.
• Applications: Ideal for measuring liquid levels and pressure in tanks, reservoirs, and other water treatment processes where the medium is non-conductive or has low conductivity.
• Advantages: High accuracy, excellent stability, and resistance to corrosion and fouling.
• Limitations: Not suitable for measuring pressure in high-pressure or high-temperature applications.

2. Piezoresistive:

• Principle: This technique uses a strain gauge bonded to a silicon diaphragm. The strain gauge's resistance changes proportionally to the applied pressure, which is then converted into a pressure reading.
• Applications: Suitable for monitoring pressures in pumps, filters, and pipelines, providing reliable data for process control.
• Advantages: Wide measurement range, high accuracy, and compatibility with various fluids.
• Limitations: Can be susceptible to temperature variations, requiring temperature compensation in some applications.

3. Other Techniques:

• Differential Pressure: This technique measures the pressure difference between two points, enabling the measurement of flow rates, level, and pressure drops across devices like filters.
• Gauge Pressure: This technique measures the pressure relative to atmospheric pressure.
• Absolute Pressure: This technique measures the pressure relative to a perfect vacuum.

Selection of Techniques:

The choice of measurement technique for Cerabar pressure transmitters depends on factors like:

• Medium: The properties of the fluid being measured, such as its conductivity and viscosity.
• Pressure Range: The expected pressure range in the application.
• Accuracy Requirements: The level of accuracy needed for the measurement.
• Environment: The environmental conditions, such as temperature and corrosion resistance.

By understanding these techniques and their suitability, users can select the optimal Cerabar transmitter for their specific application.
