Dwyer Series 43000 Capsu-Photohelic Pressure Switch Gage 43230S

Dwyer Series 43000 Capsu-Photohelic® Pressure Switch Gage 43230S

The Dwyer Series 43000 Capsu-Photohelic® Pressure Switch Gage 43230S is a versatile instrument that combines precise pressure measurement with reliable switching capabilities. Designed for both liquids and gases, it operates effectively at pressures up to 500 psig (34 bar).

Key Features

• Dual Functionality: Integrates a highly repeatable pressure switch with an accurate pressure gage, utilizing the proven Magnehelic® gage design.
• Encapsulated Sensing Element: Ensures compatibility with a wide range of media, including both liquids and gases.
• Dual DPDT Relays: Equipped with two phototransistor-actuated, double-pole double-throw relays for precise low and high limit control.
• Adjustable Set Points: User-friendly knobs on the gage face allow for easy adjustment of set points, with individual set point deadband being less than 1% of full scale.
• Variable Deadband Control: Set points can be interlocked to provide variable deadband, making it ideal for applications such as pump control.
