Question What are my options for mounting an accelerometer at or above 250°F? Answer There are several options for mounting devices to each other at that temperature. Screw mounting an accelerometer is always best. There is no problem handling temperature if properly torqued (see relevant product data sheet for correct mounting torque), and the component […]

I am concerned that my “less than clean” lab environment may be contaminating some of my devices and introducing unwanted noise in my measurement system. This is a great question and one deserving of a detailed answer. Vibration monitoring transducers require intimate contact with the vibration producing device. Pressure transducers require a tight seal to […]

To provide accessibility to charge converters we are running soft cable lengths between 85′ to 130′ between the accelerometers and the charge amplifiers. We will be replacing Endevco #3090C-600 soft cable with Endevco #3097M1. I know you can’t run these forever in distance but I have not seen it documented anywhere in your literature on […]

Question What special considerations should I take to properly integrate and mount my 2222C transducer to get the best results? Answer The 2222C is a light weight, high g, Piezoelectric transducer and is an excellent choice for modal testing and analysis. Its light weight minimizes any mass loading influences that might result from larger sensors […]

Question I want to measure linear acceleration (~10g, DC to 20Hz) on a rail vehicle. From looking at your range of accelerometers, either a capacitive accelerometer (7290A) or piezoresistive accelerometer (2262A) would suit. What are the advantages and disadvantages of capacitive and piezoresistive accelerometers (e.g., shock survival, accuracy, drift, overrange recovery time)? Answer For your […]
