Technical details and manufacturing context for Signal Transmitter

Definition
A signal transmitter is a critical component within pressure and temperature sensor systems that receives raw electrical signals from sensing elements, conditions and amplifies these signals, and converts them into standardized output formats (such as 4-20mA, 0-10V, or digital protocols) suitable for transmission over distances to monitoring, control, or data acquisition systems.
Working Principle
The transmitter receives low-level electrical signals from pressure or temperature sensing elements (like strain gauges, RTDs, or thermocouples), amplifies and linearizes the signal, applies temperature compensation if needed, then converts it to a standardized industrial output signal through signal conditioning circuits and output drivers.
Common Materials
Printed Circuit Board (PCB), Electronic Components (ICs, resistors, capacitors), Housing (stainless steel or aluminum alloy), Connection Terminals
