Special Report: Signal conditioners ensure signal integrity
Employed wherever temperature, pressure, flow, speed or other process values are measured and controlled, signal conditioners help protect these measurements from being corrupted as they transmit the measurement data from the field where the sensors collect data to the plant control room.
Signal conditioners ensure signal integrity
Like a fuel injector in a high-performance engine, signal conditioners perform a critical, yet often under-recognized function. Signal conditioners isolate, transmit and convert a wide range of process signals into a format that is compatible with the receiving device such as a programmable logic controller.
