Product Overview
High-Purity Indicating Pressure Switch Gauge, HA Action (Unused NOS)
This compact indicating pressure switch gauge combines local indication with a discrete switch output for clean, controlled pressure monitoring. Built for high-purity service, it supports alarm and interlock functions without continuous power to the switch. Practical tip: set the switch index within the mid-span for the most repeatable actuation in PSI / bar systems.
Product Condition
Unused, New Old Stock. Factory clean-room packed and kept in original manufacturer packaging.
Product Overview
The Ametek IPS-200-HA integrates a 2 in pressure gauge with a magnetically actuated, hermetically sealed reed switch. The HA configuration closes on increasing pressure, providing a reliable on-off signal at an adjustable setpoint. A seamless, TIG-welded stainless body and electropolished 316L wetted path support high-purity and corrosive gas applications.

Frequently Asked Questions
Is this a transmitter with an analog output?
No. It is a switch gauge that provides a discrete on-off output at a set pressure, not a proportional signal.
How is the switch setpoint adjusted?
The setpoint is adjusted from the front by moving the dial index to the desired trip pressure.
Does the switch require input power?
The reed switch itself operates magnetically and does not require input power to actuate.
What makes it suitable for high-purity service?
The electropolished 316L stainless wetted path and helium leak testing support clean gas handling.
You can add a reliable pressure alarm by installing this gauge on a 1/4 in port and wiring the reed switch contacts to a low-voltage relay or PLC input on your control panel.
