Dwyer Instruments gauges' part numbers cross-reference to various Dayton & Ashcroft products. So, if you're looking for a Dwyer Instruments part that is either obsolete or out of stock, chances are we have the equivalent item available.
Dwyer Instruments units require simple packaging and are suitable for courier shipment & air freight.
Dwyer Instruments' catalogue includes a wide range of pressure, flow, temperature, level and air quality measurement instruments. The brand's Magnehelic differential pressure gages provide a quick indication of air or noncorrosive gas pressures (either positive, negative or differential). They feature a rugged design to resist shocks, vibrations & overpressures and a bezel fitting to provide easy flush mounting in panels. These Dwyer differential pressure gages come with a precision litho-printed scale for easy reading and moulded rubber pointer stops to prevent over-travel. They are integrated with a silicon rubber diaphragm to support the front & rear plates and prevent damage due to overpressures. The brand's digital handheld manometers feature a single-button auto-zero function that offers easy on-site calibration and reset facilities. They further come equipped with an extruded aluminium housing to withstand temperatures up to 140 degrees F. These handheld manometers are suitable for measuring positive, negative and differential pressures with +/-0.10% full-scale accuracy.
They provide simple, frictionless movement for quickly indicating positive, negative (vacuum) & differential air or non-corrosive gas pressures. They are shock, vibration, water & over-pressure resistant.
They detect the pressure of air and compatible gases and provide a 4 - 20mA output signal. The polycarbonate moulded housing has integral pressure connections, which saves time during installation. It is made to fit in the same diameter cutout as a standard Magnehelic gauge.
These monitors are ideal for critical low differential pressure applications requiring precise pressure monitoring. They can be configured to monitor positive or negative pressure in protected and clean areas. They allow access to pressure, security, calibration and alarm configuration.
These precision machined, direct reading flowmeters have a clear acrylic body and are suitable for both gas & liquid applications. They are available with 2 inch (51 mm) and 4 inch (102 mm) scales, as well as optional precision metering valves.
These transmitters can detect air and non-combustible gas pressures. Their polycarbonate moulded housing is integrated with pressure connection points to save time during installation. They have an easy-to-read LCD for easy pressure readings display.
These monitors are ideal for critical low-differential pressure applications requiring precise pressure monitoring. They can be configured to monitor positive or negative pressure in protected and clean areas. These units have a password-protected setup menu and visual LED alarms.
These direct reading flowmeters have a white background for easy reading and are suitable for both gas & liquid applications. Their precision-machined tapered bore enables high repeatability.
These Dwyer Instruments pressure gauges quickly indicate positive, negative (vacuum) & differential air or non-corrosive gas pressures. They are IP67-rated and resist shock, vibration, water & overpressures.
Yes, their front covers are sealed with O-rings. When installing indoors, the pressure connections leading downward from the gauge should be provided maximum protection from the elements.
The diaphragm can sag in planes other than the vertical plane, causing a shift in set-point or a change in the adjustable set-point range. Even at the smallest set-points, the switch may fail to reset. This is the same phenomenon that causes inaccuracy in Magnehelic and Capsuhelic gauges when they are not mounted vertically.
Yes, Dwyer Instruments products are pre-calibrated for applications like HVAC, industrial processes and laboratories to provide accurate measurement readings.
Dwyer Instruments offers a wide range of products for various application needs, including:
Dwyer carrying cases are designed to keep the valuable test instruments safe while transportation. These units are made of nylon for weather resistance and feature internal soft padding for maximum protection against shocks and impact blows.
