Head Mounted Transmitters

Head-mounted transmitters are compact, puck-shaped devices designed for direct installation within the protective connection head of a temperature probe. Their close proximity to the sensor minimises the risk of signal degradation and electrical noise, ensuring highly accurate measurements. These transmitters convert the low-level signal from a thermocouple or RTD into a robust, standardised 4-20mA or digital signal, which can be reliably transmitted over long distances to a control system. Their small form factor and integration with the sensor assembly make them ideal for seamless and efficient temperature monitoring in a wide range of industrial applications.
