How to Connect a Pressure Transducer to a Data Acquisition System for Accurate Measurement

Accurate measurement of pressure is essential for many industrial and scientific applications. A pressure transducer is a device that converts pressure into an electrical signal, which can then be measured and recorded by a data acquisition system. Connecting a pressure transducer to a data acquisition system requires careful consideration of the transducer’s electrical characteristics and the data acquisition system’s capabilities. The first step in connecting a pressure transducer to a data acquisition system is to select a transducer that is compatible with the system. The transducer should have an output signal that is compatible with the data acquisition system’s input range. Additionally, the transducer should have a signal type that is compatible with the data acquisition system’s input type. For example, if the data acquisition system has an analog input, the transducer should have an analog output.

Once the transducer is selected, it must be connected to the data acquisition system. The transducer should be connected to the data acquisition system’s input terminals using the appropriate cables and connectors. The transducer should be connected in accordance with the manufacturer’s instructions. Additionally, the transducer should be connected to a power source that is compatible with the transducer’s power requirements.

Measuring principle	Thin–film–on–steel
Measuring range	0 ~ 5bar…2,500bar [ 100…to 36,000psi ]
Output signal	4…20mA, 0.5…4.5VDC, 0…5VDC, 0…10VDC
Accuracy	± 0.25% FS, ± 0.5% FS, ± 1.0% FS
Response time	≤1ms
Durability	10 million cycles

Finally, the data acquisition system must be configured to accurately measure the transducer’s output signal. The data acquisition system should be configured to measure the transducer’s output signal within its specified range. Additionally, the data acquisition system should be configured to measure the transducer’s output signal with the appropriate resolution and accuracy. By following these steps, a pressure transducer can be connected to a data acquisition system for accurate measurement. Careful consideration of the transducer’s electrical characteristics and the data acquisition system’s capabilities is essential for successful connection and accurate measurement.
