HVAC air handling and ventilation

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 Kimo SF50 Series is a simple and reliable passive temperature sensor. The SF50 can be performed as PT100, PT1000 or NTC sensor. The sensors are tailor made so you can determine the sensor and cable length yourself.

The Kimo TB50 series is a temperature sensor with a robust housing. By default, the sensor has a PT100 output, but it can also be mounted by the CO-P in the head as a 4-20 mA transmitter. The optional thermowell allows assembly and disassembly without disturbing the process.

The Dwyer CDT series CO2 transmitters are equipped with an NDIR (infrared) sensor. The transmitters are available in a wall-mounted version and in a version for duct mounting. Optionally, the transmitters are also available with a temperature output and SPST relay contact. Unique for this CO2 measurement is that it can also be used for rooms that are used 24 hours a day. Other sensors use the p...

The ATEX certified AT2DH3 series Digihelic® differential pressure controller is a 3-in-1 instrument that consists of a digital differential pressure gauge, relay contacts for alarms, or on-off control and a transmitter output. The AT2DH3 can also be used to measure air velocities and flow in combination with a pitot tube. The AT2DH3 has an analogue 4-20 mA output and two SPDT relay contacts wit...

The ATEX approved AT1ADPS differential pressure switch is designed for overpressure, underpressure and differential pressure applications in potentially hazardous areas. The large adjustment knob with scale makes it very easy to set the switching point. The AT1ADPS differential pressure switch is available in different switching ranges between 20 and 4000 Pa. The aluminum flame proof ATEX housi...

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.

The MiniAir64 vane anemometer measures the speed of gaseous media and water, with a direct 4-20mA output. The Swiss Precision MiniAir64 Vane probe is unique. The lamella rotation has a very low resistance and is not affected by pressure, temperature, density and humidity. The MiniAir64 is also available with an ATEX certificate.

The Dwyer CDWP series consists of inductive CO2 transmitters for, for example, livestock farming (chicken barns), technical areas, monitoring of CO2 cooling systems and greenhouses. The CDWP measures the carbon dioxide content with an infrared (NDIR) measuring cell with a long lifespan. This sensor technology offers the highest accuracy compared to automatic baseline correction (ABC logic), whi...

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...
