WebSep 1, 2009 · For such transmitters, the response time of the overall pressure-sensing system from the process to the transmitter output is a strong function of the sensing line’s length and diameter. Table 1. WebFor example, the morning team at one station heard dead air on their monitors and assumed the station’s transmitter had died. That was mistake #1. In fact, what had happened was the live assist had finished and the program stopped. But, they decided blaming the transmitter would cover their goof – and turned on the auxiliary transmitter.
