Ashcroft B461V Industrial Differential Pressure Switch

Ashcroft B461V Industrial Differential Pressure Switch is a rugged B-Series instrument that converts a sensed differential pressure into a switch signal to drive alarms or control equipment in industrial systems. As part of the B-Series, the B461V is designed for monitoring differential pressure across filters, ducts, or other process elements where maintaining a defined pressure relationship is critical. The device offers field-adjustable setpoints and a choice of electrical configurations to suit signaling and control needs, backed by Ashcroft’s durable, industrial-grade construction that supports long-cycle operation in harsh environments. Typical applications include HVAC filter monitoring and room-pressure or cleanroom control, dust-collection system supervision, and protection of fans, blowers, and pneumatic equipment by flagging when differential pressure exceeds a configured threshold. The B-Series family provides a broad range of differential pressure options, installation guidance, and performance data documented in Ashcroft datasheets. Exact specifications—such as differential pressure ranges, setpoint adjustability, electrical ratings, and enclosure compatibility—vary by model; consult the official B-Series datasheet for the precise details and to confirm compatibility with your process connections.
