The Series MS Magnesense^® Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure and air velocity. This compact package is loaded with features such as: field selectable English or metric ranges, field upgradeable LCD display, adjustable dampening of output signal (with optional display) and the ability to select a square root output for use with Pitot tubes and other similar flow sensors.

The Series ADPS Adjustable Differential Pressure Switch is designed for pressure, vacuum, and differential pressures. The dual scaled adjustment knob in inches water column and Pascals allows changes to the switching pressure to be made without a pressure gage. The ADPS is available with settings from 0.08″ w.c. (20 Pa) up to 16″ w.c. (4000 Pa). The silicone diaphragm and PA 6.6 body make the series ADPS ideal for use with air and other noncombustible gases. The compact size, adjustment knob and low cost make the ADPS the perfect choice for HVAC applications.

The ATEX approved Series AT1ADPS Adjustable Differential Pressure Switch is designed for pressure, vacuum, and differential pressure applications in hazardous areas. The dual scaled adjustment knob in inches water column and pascals allows changes to the switching pressure to be made without a pressure gage. The switch is available with settings from 0.08 in w.c. (20 Pa) up to 16 in w.c. (4000 Pa). The silicone diaphragm makes this series ideal for use with air and other noncombustible gases. Flame-proof ATEX enclosures are available in aluminum and can include a glass window for viewing set point status on adjustment knob.

Our most popular Differential Pressure Switch is now available in an flame-proof ATEX approved package in the AT11910 Series. This pressure switch combines advanced design and precision construction to make these switches able to perform many of the tasks of larger, costlier units. For air and non-combustible compatible gases, the AT11910 Series switches have set points from 0.07 to 20 in w.c. (1.8 to 508 mm). Set point adjustment is easy with range screw located inside the switch enclosure. Series AT11910 ATEX enclosures are available in aluminum enclosures and ideal for low pressure, hazardous area applications.

Model AQH-20, Handheld Indoor Air Quality Meter,Measures CO₂, Temperature and Humidity

The Model AQH-20 Indoor Air Quality Meter reduces the number of instruments a contractor has to carry by measuring the carbon dioxide concentration, air temperature, and humidity percentage in one device. A large backlit LCD display shows all three parameters simultaneously. The Model AQH-20 can display dew point or wet bulb temperatures in place of the ambient temperature. Minimum, maximum, and average readings are easily accessible through the function buttons. By pressing the hold key, the current values are held so that they can be recorded. An audible alarm warns the user that the current ambient conditions are becoming hazardous. The Model AQH-20 includes a hard carrying case and four AA alkaline batteries.

Model CDD, Duct Mount Carbon Dioxide Transmitter, NDIR Sensing Technology, 2000 PPM Range

The Model CDD Duct Mount Carbon Dioxide Transmitter monitors the occupancy in a room by detecting the concentration of carbon dioxide in the return air duct. The non-dispersive infrared sensing technology automatically updates the calibration of the transmitter using a proprietary logic feature which limits the amount of error due to drift. The Model CDD can measure up to 2000 PPM in duct air flows less than 1500 FPM.

Contrôleur de débit à palette

Le débit du liquide à contrôler entraîne la palette du CDP. Le levier solidaire appuyant sur un ressort comporte un aimant permanent en partie supérieur qui actionne l?ampoule Reed insérée dans la tête. Les contrôleurs CDP sont montés en ligne sur la tuyauterie jusqu’au DN 50 avec un manchon taraudé gaz. Pour les diamètres supérieurs, ils sont fixés par un bossage ½” gaz femelle.

Débitmètre métallique à lecture indirecte

Un ludion équipé d’un aimant subit la poussée du fluide à contrôler dans un tube cylindrique à fentes coniques. La série BMV sera réservée à un montage vertical, fluide ascendant pour des liquides ayant une viscosité sensiblement égale à l’eau. Ces appareils sont susceptibles d’assurer la mesure et le contrôle de circulation d’air (plages spéciales en air – 1 bar ABS uniquement sur demande). Le flotteur comporte un aimant qui entraîne l’aiguille d’un indicateur. L’accouplement magnétique est réalisé de telle manière que l’indication ne peut être perdue quelle que soit la vitesse de montée du flotteur. Un contact ILS (Reed) est disposé sur une glissière à l’extérieur et s’enclenche dès que le flotteur passe devant. Le contact est du type bistable normalement ouvert par manque de débit.
