616WL-32 is a series 616WL differential pressure transmitter. It senses very low pressures of air and non-combustible, compatible gases and sends a standard 4-20mA output signal. It features NEMA 4X rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists. Zero and span controls provides easy calibration checks and shorter installation time to get device running and monitoring. High precision accuracy at low pressure ranges provides exceptional accuracy for insuring tight-control and minimizing costly out-of-specification conditions. Typical applications include low pressure applications, dust collection, outdoor HVAC and roof-top equipment.
