PRESSURE TRANSMITTERS
Pressure transmitters are essential components for monitoring and managing the pressure of a fluid (liquid or gas) in a system and converting this measurement into an electrical signal that can be read by a control or monitoring system.
They work by means of sensors that detect the pressure variation and convert it into a proportional signal. The main types of pressure transmitters include those with piezoelectric, capacitive, strain gauge and resistive technology, each with specific characteristics that make them suitable for different applications.
Compared to pressure switches, pressure transmitters offer numerous advantages, including:
- Continuous and precise measurement: provide accurate, real-time data for condition monitoring. Instead of an ON/OFF contact, the transmitters provide a continuous signal proportional to the chosen pressure range.
- Automation and integration in control systems: given the multiple possibilities of output signals 4/20 mA, 0-10 Volt, 0.5...4.5 Vol etc... they interface with PLCs, SCADA and other systems for advanced process management.
- Increased reliability and durability: designed to withstand pressure variations, vibrations and harsh environmental conditions.
- Operational efficiency: optimise energy consumption and prevent failures due to abnormal pressure.
- Versatile applications: used in sectors such as industrial automation, the oil and chemical industry, agriculture, the food industry and water management.
