About Dwyer Series 2300 Magnehelic Differential Pressure Gauge

Dwyer Series 2300 Magnehelic Differential Pressure Gauge

Indicate Positive, Negative or Differential, Accurate within 1%

Select the SERIES 2000 Magnehelic Gage for a versatile low differential pressure gage with a wide choice of 81 models and 27 options to choose from. Using Dwyers simple, frictionless Magnehelic gage movement, it quickly indicates air or noncorrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67. Select the -HA High Accuracy Magnehelic Gageoption for an accuracy within 1% of full scale, located below in the Product Configurator. Also included with the HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.

Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

FAQs of Dwyer Series 2300 Magnehelic Differential Pressure Gauge:

Q: How do I install the Dwyer Series 2300 Magnehelic Differential Pressure Gauge?

A: The gauge can be mounted in any orientation using surface or flush methods. All necessary mounting rings and hardware are included. Ensure the dual 1/8" NPT process connections are securely attached to your high and low pressure lines before use.

Q: What types of media can this gauge measure pressure for?

A: This instrument is designed to measure the differential pressure of air and non-combustible gases only. Avoid using it with liquids or corrosive gases, as this may damage the internal mechanisms and compromise accuracy.

Q: When should I use the zero adjustment feature?

A: Use the external zero adjustment screw before each series of measurements or if you notice the pointer off zero when there is no pressure difference. This helps maintain consistent accuracy as environmental conditions or installation position change.

Q: Where can this gauge be used?

A: The gauge is suitable for industrial environments, including HVAC systems, cleanrooms, filter monitoring, and laboratories. Its weatherproof case allows for use in less controlled environmentsplease consult the manufacturer for detailed ingress protection recommendations.

Q: What is the benefit of the low hysteresis mechanism in the Magnehelic gauge?

A: The low-friction mechanism minimizes hysteresis, ensuring you obtain highly consistent readings during both increasing and decreasing pressure cycles. This enhances overall accuracy and reliability, especially in applications demanding precise monitoring.

Q: How do I read the measurements on the dial?

A: The display features a clear round acrylic dial with fine increments, available in multiple pressure units including inches of water column, pascals, mm wc, and kPa. Select a scale range that matches your application for optimal resolution and clarity.
