Dwyer Instruments 43000-40CM Analog Pressure Gauge with 4-20 mA Output

The Dwyer Instruments 43000-40CM Analog Pressure Gauge is a versatile and highly repeatable pressure switch/gauge designed for demanding industrial applications. Combining the time-proven Magnehelic gauge design with an encapsulated sensing element, this instrument provides accurate pressure measurement and reliable switch control for both liquids and gases at pressures up to 500 psig (34 bar). With a 0-1000 psi range and 4-20 mA output, the 43000-40CM is a compact, rugged solution for process control and automation.

Key Features & Highlights

• Dual Functionality: Combines a precise analog pressure gauge with a highly repeatable pressure switch, eliminating the need for separate instruments.
• Encapsulated Sensing Element: Suitable for use with both liquids and gases, providing reliable performance in diverse media.
• 4-20 mA Output: Enables seamless integration with control systems and remote monitoring.
• Adjustable Set Points: Easy-to-adjust knobs on the gauge face allow for quick set point changes, with individual deadband less than 1% of full scale.
• DPDT Relays: Two phototransistor-actuated relays provide low/high limit control, with interlock capability for variable deadband.
• Rugged Construction: Built to withstand industrial environments, with optional cast brass case for water-based liquids.

Applications

The Dwyer Instruments 43000-40CM is ideal for a wide range of industrial process control applications, including pump control, HVAC systems, filtration monitoring, and liquid level measurement. Its compact design and robust features make it a reliable choice for automation and control panels.
