  "textContent": "The control circuit only initiates a pressure measurement when the pressure or temperature analog signal from a sensor falls outside set threshold values. The threshold values are set from previously observed analog signals. Sampling of the values takes place in shorter time intervals, e.g. 1 minute, than setting of the threshold values, e.g. 30 minutes, to eliminate transient disturbances. An Independent claim is also included for a pressure monitoring arrangement that makes the decision to undertake a pressure measurement dependant on the magnitude of the change in the pressure or temperature signal from a sensor (S). When a wake-up signal is generated, analog/digital conversion of the pressure signal takes place and the result is transmitted by a radio signal transmitter (TNS).",
