HVAC air handling and ventilation

The Dwyer Magnesense Series MSX Pro differential pressure transmitter is the professional differential pressure transmitter that meets rigorous industry standards with innovative product design. The instrument has exceptional stability for use in critical building applications with the versatility of our original series Magnesense transmitters. Pressure ranges in Pa, mmH2O, and inWC are availab...

The reliable IVL air velocity transmitters work on the hot-wire measurement principle, which quarantees very good accuracy at low air velocity. The transmitters are suitable for air flow and temperature measurements in the air ducts. Air velocity transmitters are available with different measurement ranges and immersion lengths, with or without display.

TEK temperature sensors are designed for automatic ventilating systems to detect duct temperature. Sensors are mounted to the duct by means of an adjustable duct connection flange for optimal temperature detection

Series 477 handheld digital manometers are packed with features you need to make pressure measurement and recording faster, easier and more accurate than ever. You can instantly select from up to nine of the most widely used pressure units. A non-volatile memory function enables storage of up to 40 readings. Other main features are: display HOLD, audible alarm, visual alarm, backlight with au...

Series 490A Digital Manometers are versatile, hand-held, battery operated manometers available in several basic ranges for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316LSS. A memory function allows storage of up to 40 readings.

The MiniAir®20 is a vane air velocity, hygrometer and thermometer in one instrument. The multifunction handheld measures flow of gaseous and fluid media, relative humidity and temperature. The high precision makes this handset particularly suitable for laboratory applications. For the measurement of flow in aggressive gases, there are also special stainless steel vane detectors.

Kimo CO2ST series is a carbon dioxide switch with indicator. The CO2ST is ideal to use as an alarm for CO2. The status LED indicates if an alarm level is exceeded and the audio-visual alarm warns at a high concentration of CO2. The installation is very easy because the enclosure can be mounted in two parts, making it ideal for installers.

PEL - differential pressure transmitters are made for clean / isolation room applications. The zero point of the transmitter remains exact by means of the automatic zeroing, eliminating regularly possible zero point drifting. The PEL has 8 measuring ranges, all selectable at commissioning. Available with or without a display.

The Series 605 Magnehelic Indicating Transmitter provides for both visual monitoring and electronic control of very low differential pressure. The Series 605 is ideal for control applications in building HVAC systems The easily read dial gage is complimented by the two-wire, 4-20 mA control signal utilizing the timeproven Dwyer® Magnehelic® gage mechanical design and Series 600 transmitter tech...

The Series 629C Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4-20 mA output signal for two wire circuits. Small internal volume and minimum moving parts result in exceptional response and reliability.
