No! In a competitive market, many companies will try to gain a competitive advantage by manipulating their specifications via creative specmanship. These efforts are not isolated to calculation of the acceleration range. Frequency response is another data point that is often manipulated because it seldom is tested.
As mentioned in Answer #1, IMI Sensors has always had the policy of specifying product for worst case scenario while other companies do not. The frequency response specification of each of IMI Sensors’ products can be confirmed by the product's calibration certificate. See Figure 2 below.
IMI Sensors ran a calibration on a competitor's sensor and found it to be out of spec. See Figure 3. Per the specifications, the sensitivity of the model was supposed to stay within 10% of the specified 100 mV/g sensitivity throughout the frequency span to 600,000 cpm. In actuality, the sensor had greater than 10% deviation before its specified high frequency limit. The deviation at 600,000 cpm was almost 80%, producing a 180 mV/g sensitivity.
If you have any questions on any sensor specification, please contact one of IMI Sensors’ Application Engineers. It is important to know what the specifications mean and when something just doesn’t add up. With IMI Sensors, your model is guaranteed to meet specifications. We give you the worst case scenario as we think it is a more honest and realistic approach.
