What is a Head Mount Temperature Transmitter?

A head mount temperature transmitter is a device used in industrial and scientific applications to convert temperature sensor signals, such as those from thermocouples or RTDs (Resistance Temperature Detectors), into standardized output signals like 4-20mA, HART, or digital signals. These transmitters are mounted directly on the temperature sensor's head, providing accurate and reliable temperature measurements crucial for process control and monitoring.
