Advantages of Pressure Transducer
 

Accurate process control: Pressure sensors play an indispensable role in the process. For example, in the chemical, petroleum, and water treatment industries, we need to know the height of the liquid level accurately. By installing the pressure sensor at the bottom of the tanks, we can sense the pressure on the pressure sensor and use the formula to calculate the liquid level.

 

Maximize economic benefits: The use of pressure sensors has greatly improved production efficiency and reduced labor costs. For example, the pressure level values that need to be manually measured and recorded can be directly transmitted to the computer through the back-end system, and manual processing is only required when an alarm is triggered.

 

Safety assurance: There are many unsafe factors in industrial scenarios, so it is very important to ensure safety in the production process. For example, in the chemical industry, for the pressure and level measurement of flammable and explosive gases and liquids, it is necessary to select products with explosion-proof performance.

 

Energy saving: In the chemical industry, chemical reactions require specific pressure to maintain. While monitoring the pressure, the pressure sensor avoids incomplete chemical reactions due to insufficient pressure in the reaction, which leads to energy waste.

 

Suitable for various applications: Pressure sensors are widely used in a variety of application fields. Such as petrochemical, air conditioning and refrigeration, pipeline pressure monitoring, industrial process control, etc. The measuring media include oil, water, gas and chemical media. There are also corresponding solutions for corrosive gas and liquid.

 

High reliability: The pressure sensor is made of materials with low thermal expansion coefficients, such as single crystal silicon, ceramics, and stainless steel. Even if the ambient temperature changes, the product will not deform.

Types of Pressure Transducer

 

 

Explosion proof pressure transducer: Intrinsically safe pressure transducer are for applications in high risk environments. We also have explosion proof pressure transducers for extremely hazardous environments.


Sanitary pressure transducer: It also called snap on pressure transducer, which combines proven thin film transducer technology with a sanitary isolation seal. It is essential in hygienic processing environments such as the food and pharmaceutical industries.


Diaphragm pressure transducer: A diaphragm pressure transducer is a mechanical device that converts pressure changes into an electric signal, which can be measured to gauge changes in pressure. Diaphragm pressure transducers are particularly useful for low pressure transducer applications.


Submersible pressure transducer: These are also known as liquid level meters and are used to measure the pressure in water tanks and other similar applications.


Sil-2 pressure transducer: These are for applications with a safety integrated performance level requirement.


Combined pressure and temperature transducer: We also have a range of pressure transducers which are combined with temperature transducers. This allows the one transducer to take two measurements, perfect for applications in small spaces and well proven in motorsports in particular.


Extrusion pressure transducer: It also called the high temperature high pressure transducer, which used to measure pressure along the extruder barrel and at the screen changer, melt pump, and extruder die.


General pressure transducer: We have a range of pressure transducers which includes various sizes and pressure ranges – see them all on our website.

Key Components of a Pressure Transducer

 

Sensing element:

This is part of the transducer that comes into contact with the substance being measured and translates the physical pressure into a mechanical or electrical signal.

01

Diaphragm:

A flexible membrane that is commonly used as the sensing element. The diaphragm will deform in response to changes in pressure, which is then translated into an electrical signal.

02

Strain gauge:

A type of sensing element that uses a wire or foil that changes resistance in response to mechanical stress. Strain gauges are often used with a diaphragm to measure pressure.

03

Amplifier:

The electrical signal generated by the sensing element is typically very small and needs to be amplified by the transducer’s electronics to produce a usable output signal.

04

Output signal:

The final output signal can take many forms, such as a voltage, current, or frequency, depending on the transducer’s design and intended application.

FAQ

 

 

Q: What is the accuracy of pressure transducers?

A: The accuracy of pressure transducers can vary depending on the manufacturer and model. High-quality transducers can have accuracies of +/-0.05% of full scale, while lower-cost transducers may have accuracies of +/-1% or more.

Q: What is the maximum pressure range of pressure transducers?

A: The maximum pressure range of pressure transducers can vary depending on the manufacturer and model. Some transducers can measure pressures as low as a few millibars, while others can measure pressures up to tens of thousands of psi.

Q: Can pressure transducers measure vacuum?

A: Yes, pressure transducers can be used to measure a vacuum where the output can either increase with increasing pressure or decrease. However, the transducer’s range and measurement accuracy may be different for vacuum measurements compared to positive pressure measurements.

Q: How do I select the right pressure transducer for my application?

A: When selecting a pressure transducer, consider factors such as the pressure range, accuracy, output signal, environmental conditions, and temperature.
