Advantages and disadvantages of feeding vibration and displacement signals directly into the SIS system to eliminate 3500 frame instruments?

What are the advantages and disadvantages of using vibration and displacement sensors, connected via pre-amplifiers directly to the SIS system, in place of 3500 frame instruments?
You must have made a mistake; it shouldn’t go through a preamplifier, but rather a field transmitter. SIS is unable to process these signals.
Vibration and displacement sensors pass through pre-amplifiers, then to the transmitters in the SIS, and finally to the alarm setting device
1. Why do you want to cancel the transmitter? 2. Do you know that your SIS system can accept physical signals?
The probe needs to pass through a transmitter in order to output a 4-20mA signal. Do you mean that it won’t be sent to the ETS system (turbine interlock shutdown system), but can be sent to the SIS system instead?
