P15M Series Teflon® Gauge Pressure Switch from UE Precision Sensors

P15M Series Teflon® Gauge Pressure Switch from UE Precision SensorsThe P15M Series Teflon® Gauge Pressure Switch from UE Precision Sensors is purpose-built for high-purity wet process environments where traditional stainless steel components are not suitable. Designed to monitor pressure above atmospheric levels, the P15M Series delivers reliable switching performance in chemically aggressive applications.

With advanced fluoropolymer construction and precision switching technology, the P15M Series is ideal for chemical delivery systems, DI water processes, and other environments where corrosion resistance and cleanliness are critical.

Features

P15M Series Teflon Gauge Pressure Switch Features & Benefits 

  • Engineered for Corrosive & High-Purity Environments - Unlike standard pressure switches, the P15M Series uses fluoropolymer materials such as PFA and PTFE for wetted parts, making it highly resistant to aggressive chemicals.
  • Ideal Alternative to Stainless Steel Designs - In applications where 316L stainless steel is not acceptable, the P15M provides a reliable solution without compromising performance.
  • Accurate & Repeatable Switching - A negative-rate spring mechanism enhances setpoint stability and repeatability, helping maintain consistent control in critical processes.
  • Multiple Configuration Options

    • P15M: Factory-set, tamper-resistant
    • 2P15M: Dual-switch capability for monitoring two conditions
    • P15M-A: Field-adjustable version for flexibility

    These options allow users to match the switch precisely to their application needs.

  • Excellent Chemical Resistance - Designed specifically for wet chemical systems, the P15M Series performs reliably in environments where other materials may degrade or fail.

P15M Series Teflon Gauge Pressure Switch Q & A

+What is the P15M Series Teflon® gauge pressure switch used for?
The P15M Series is used to monitor and control pressure in high-purity wet process systems, particularly where corrosive chemicals or ultra-clean fluids are present. It activates electrical switching at a defined pressure threshold for control or safety functions.
+Why choose a Teflon® (PFA/PTFE) pressure switch instead of stainless steel?
Fluoropolymer materials offer superior resistance to corrosive chemicals and prevent contamination in sensitive processes. This makes the P15M Series ideal for applications where metal components could degrade or introduce impurities.
+What configurations are available in the P15M Series?
The series includes factory-set (P15M), dual-switch (2P15M), and adjustable (P15M-A) models, allowing users to select the best option for their application requirements.
+How accurate is the P15M Series pressure switch?
The P15M Series offers strong repeatability (as low as ±0.5 psi + 2% of setpoint), ensuring consistent switching performance in critical systems.
+What industries commonly use the P15M Series?

It is widely used in semiconductor manufacturing, chemical processing, and DI water systems—anywhere corrosion resistance and high purity are essential.
