Displacement Sensor Topic: Temperature of Sensing Object Affects Detection Ability

FAQ No. FAQ01451

Question

Does the temperature of the sensing object affect the detection ability of E4PA Ultrasonic Sensor?


Answer

A temperature compensation circuit is built into the setting plug, but the output value varies with the temperature of the sensing object and the ambient temperature.

(±1% FS of the output value at 23°C in the range of -10°C to 55°C.)

When the temperature of the sensing object exceeds 55°C, an air swirl is generated around the object. In some cases, this may cause a detection error.
