What Are the Key Technical Specifications of IEPE Accelerometers?
IEPE (Integrated Electronics Piezoelectric) accelerometers are widely used in many fields. They work well with NI data acquisition cards, which makes them popular choices for various measurement tasks. To choose and use these accelerometers correctly, you need to know their main technical specifications. Let’s take a closer look at them. 1. Sensor Sensitivity Sensor sensitivity is one of the most important features of an accelerometer. When you buy an IEPE accelerometer, the manufacturer usually gives a standard value in the product manual. For example, “50.1mV/g” is a common value. But remember, this value is measured at a certain frequency, like 80Hz or 160Hz. It tells you how much electrical signal the sensor sends out when it senses an acceleration of 1g. This helps you understand the sensor’s readings. 2. Measurement Range It’s important to pick an accelerometer whose measurement range matches the input range of your data acquisition card. Suppose a device can measure up to 1
