I have an Endevco model 136 Signal Conditioner and I am using a transducer that has a very low sensitivity of 2.847 microvolts per g. I am trying to enter this number into the output scaling of the 136, but I see I have to round it to 3 microvolts per g. It there a way I can enter the precise value?
Yes. The Endevco 133 and 136 signal conditioners are designed for ease of entry of the accelerometer sensitivity and the desired output specified in millivolts per engineering unit. In cases where very low sensitivity transducers are used, such as high g shock accelerometers the user must either round off the sensitivity, or perform some calculations to enter the precise value. By using the following step-by-step procedure for a sensor that has a sensitivity of 2.847 microvolts per engineering unit (psi, g, etc) and has a full scale output (FSO) of 60,000 g, precise values can be entered into the signal conditioner.
