Dwyer Instruments 43000-80MM Analog Pressure Gauge
The Dwyer Instruments 43000-80MM is a high-quality analog pressure gauge from the renowned Dwyer Instruments line, designed for demanding industrial applications. This gauge combines the accuracy of a Magnehelic gauge with the versatility of a Capsu-Photohelic switch, providing both precise pressure indication and reliable switching control. With a range of 0-80 mm H2O and a 2.5-inch dial, it is suitable for a wide variety of pressure measurement tasks.
Key Features & Highlights
- Precise Pressure Measurement: Employs the time-proven Magnehelic gauge design for accurate and repeatable readings.
- Encapsulated Sensing Element: Suitable for use with both liquids and gases at pressures up to 500 psig (34 bar).
- Dual Relays: Includes two phototransistor-actuated DPDT relays for low/high limit control, ideal for automation and process control.
- Adjustable Set Points: Easy-to-adjust set point indicators with knobs on the gauge face; individual deadband is less than 1% of full scale.
- Interlock Capability: Set points can be interlocked to provide variable deadband, perfect for controlling pumps and other equipment.
- Durable Construction: Stainless steel case and 1/4 NPT connection ensure long-lasting performance in harsh environments.
Applications
The Dwyer Instruments 43000-80MM is ideal for use in HVAC, cleanrooms, pharmaceutical manufacturing, and general industrial processes where precise pressure monitoring and control are critical. It is particularly well-suited for applications involving air or compatible gases and liquids, such as filter monitoring, tank level measurement, and pump control.
