Transmitters

• Air velocity transmitters

  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.

• Concentration transmitters

  Our gas concentration transmitters are selective for a specific gas, this quarantees that the real measurement value is obtained i.e ppm value of CO2 concentration. Carbon dioxide transmitters are suitable for the measurement of CO2 in indoor applications. They are self calibrating (ABCLogicTM) and are available with and without display.

• Differential pressure transmitters

  Piezoresistive PEL transmitters have been since 1991 pioneers in the differential pressure transmitter design. Differential pressure transmitters are suitable for detecting pressures and pressure differences of the air-handling system as well for under- and overpressure control of the clean rooms. From PEL transmitter range it is possible to find suitable product for the demanding low pressure measurements as well for the standard measurements in the ventilation systems. The transmitters are available with and without display.

• Humidity transmitters

  Humidity and temperature transmitters are suitable for the measurement of humidity and temperature in indoor and outdoor applications as well on the air ducts. The transmitters are also available with display, that shows the both measurement readings.

• Illumination transmitters

  Illumination transmitters are suitable for the measurements in indoor and outdoor applications. The sensor element reacts to the light like the human eye. This feature makes the measurement accurate even in the dusk. Outdoor transmitters with integrated temperature measurement reduce the cabling and installation work.

• Water pressure transmitters

  Our product range includes differential pressure and static pressure transmitters which are suitable for measurements in both heating and cooling systems. Suitable measurement range can be chosen at commissioning stage. The transmitters are available with and without display.

• Wind and rain sensors

  Our product range includes a also wind speed detector TUNA 20, which has been designed to measure wind speed and outside air temperature. High wind shield factors cool down buildings faster and with wind measurement the heating system can be compensated to take the cooling effect into account. SA 10 is a rain sensor made for HVAC applications for detecting and monitoring rain.
