Pressure Transducers are essential in today’s high-tech world. They play a vital role in a variety of industries including the automotive, aerospace, and medical sectors. What is a pressure sensor, though? What is a pressure transducer and why are they so important? SUCO ESI North America specializes in high-quality transducers. In this blog, we will explain everything you need about these essential devices.
What is a pressure transducer?
A pressure transducer, also known as a pressure sensor or pressure transmitter, is a device used to measure and convert pressure–essentially the force applied per unit area–into an electrical signal. The electrical signal is then used by control systems for monitoring and managing processes in various applications.
In industries that require pressure monitoring, such as the following:
- Automotive (e.g., tire pressure monitoring)
- Aerospace (e.g. monitoring fuel or hydraulic pressure)
- Industrial processes (e.g., managing pipeline pressure)
- Medical devices (e.g., blood pressure monitoring)
How does a pressure transducer work?
This is how a typical transducer works:
- Sensing Elements: is the core component of pressure transducers, and it reacts directly to pressure applied. The material of this element will vary depending on its application and the environment.
- Mechanical deformation: When pressure is applied to the sensor element, mechanical distortion occurs. This change is proportional with the magnitude of pressure applied.
- Electrical output: By the built-in circuitry of the transducer, mechanical deformations are converted into electrical signals. The signal can be voltage, resistance, or current.
- Signal conditioning: The raw electrical signal in many cases is not suitable to be used directly with control systems. The transducer contains signal-conditioning circuitry that amplifies and modifies the signal so it is compatible with the standard control system.
- Output signal: The transducer will output the conditional signal. This can be analog (4-20 mA, 0-5V) or digital depending on your system requirements.
Different Types of Pressure Transducers
SUCO ESI North America offers a variety of pressure transducers that are designed for specific applications. Some of the most common types are:
- Transducers for Strain Gauge Pressure: Measure pressure using strain gauges by measuring changes in diaphragm strain.
- Piezoelectric pressure transducers: Produce an electrical charge when mechanical force is applied to a piezoelectric material.
- Capacitive pressure transducers: Measure the changes in capacitance when pressure is applied between conductive plates.
- Piezoresistive pressure transducers: Based on the change of resistance in materials when exposed to strain-induced pressure.
Applications of Pressure Transducers
Pressure transducers are essential in many applications.
- Medical devices: Monitoring the blood pressure of patients.
- Automotive: Measure tire pressure to ensure safety and performance.
- Industrial: Controlling pressure in pipelines and hydraulic systems.
- Aerospace: Monitoring fuel pressures and hydraulic systems for safe operation.
High-Temperature pressure transducers
Standard pressure transducers can fail in some environments due to high temperatures. In these cases, we offer pressure transducers that are designed to withstand extreme temperatures without compromising accuracy and durability.
Pressure transmitters are used in many industries to convert pressure into electrical signals. This is done for monitoring and controlling. SUCO ESI North America can provide the right solution for you, whether you are in the automotive, medical, or industrial fields.
