Neodyn 112P NEMA 4X, 7, 9 and 13 Flanged Diaphragm Sensor – Explosion Proof

Neodyn 112P NEMA 4X, 7, 9 and 13 Flanged Diaphragm Sensor is a specialized pressure switch engineered to simplify installations that formerly required a chemical seal with fill fluids. Designed for maximum safety in critical processes, this unit features a robust 316 stainless steel body and redundant seals with a venting mechanism, making it an exceptional choice for hazardous or corrosive atmospheres.

Description

Neodyn 112P NEMA 4X, 7, 9 and 13 Flanged Diaphragm Sensor sets a new standard for process safety by eliminating the need for complex fill-fluid chemical seals. Its design incorporates redundant seals with a unique venting system between the seals. This feature allows for immediate alarm or indication if the primary seal is compromised, ensuring that process integrity is maintained and potential hazards are detected early.

Precision in Hazardous Environments

At the heart of the 112P is the reliable Nega-Rate® Belleville disc spring sensing mechanism, which ensures accurate set point stability and vibration resistance. The unit is housed in a hermetically sealed, explosion-proof electrical assembly, making it perfectly suited for operation in volatile environments where combustible gases or dusts are present. With its direct flanged connection, this sensor provides a robust and leak-free interface for aggressive media handling.
