Transmitters are sensors with an electrical transmission output for remote indication of the difference between two pressures. They can be used for single pressure. Dwyer transmitters are designed for use with compatible gases and liquids which can be applied to both the pressure and reference ports. A few transmitters can be mounted closely together to reduce required space. Transmitters are CSA approved explosion-proof for use in the specified hazardous locations and meet NACE standards.
