Head Mounted Temperature Transmitter: Working, Applications & Buying Guide A head mounted temperature transmitter is a critical industrial instrument used for accurate and stable temperature measurement. It converts low-level signals from temperature sensors such as RTDs or thermocouples into a standardized 4–20 mA output that can be transmitted reliably over long distances. Head mounted temperature transmitter used for industrial RTD and thermocouple applications A popular industrial-grade example is the INNOVA TT-201 Head Mounted Temperature Transmitter , which is designed for accurate temperature signal conversion in demanding industrial environments. What Is a Temperature Transmitter? A temperature transmitter is an electronic device that takes the signal from a temperature sensor and converts it into a proportional electrical output, most commonly 4–20 mA. This standardized signal allows temperature data to be easily read by PLCs, DCS, SCADA systems, and i...
