To help ensure great signal quality in the electrically noisy environments of factories, power plants and process industries, the range employs special techniques of signal transmission. For medium-temperature use, where integral electronics can be used, current transmission is employed. The integral electronics inside the accelerometer convert charge to a differential current signal, which can be transmitted over very long distances up to a km or more without degradation. For high and low temperature applications, where integral electronics is not an option, the accelerometers have a differential charge output, which minimizes noise pick-up. The charge signal is then converted by a local conditioner module into a differential current signal.
