The P15M-A Series Teflon® Gauge Pressure Switch from UE Precision Sensors is engineered for high-purity wet process applications where corrosion resistance and adjustability are essential. Designed to measure pressure above atmospheric levels, this switch provides reliable control, monitoring, and safety shutdown functionality in chemically aggressive environments.
Unlike fixed-set models, the P15M-A allows users to fine-tune setpoints in the field—making it ideal for systems requiring flexibility without sacrificing performance.
Features
Features & Benefits
- Field-Adjustable Setpoint for Maximum Flexibility - The P15M-A allows users to adjust pressure settings on-site, making it easier to adapt to changing process requirements without replacing equipment.
- Designed for Corrosive & High-Purity Applications - Constructed with fluoropolymer wetted materials such as PFA and PTFE, the P15M-A resists aggressive chemicals and helps maintain system purity.
- Reliable & Repeatable Switching Performance - A negative-rate spring mechanism ensures stable actuation points and long-term repeatability, even in demanding environments.
- Leak-Tight, Compact Design - The compact form factor and leak-resistant construction make it ideal for tight installation spaces and sensitive systems.
- Built for Critical Process Protection - Supports alarm, control, and shutdown functions in systems where maintaining pressure limits is essential for safety and uptime.
