Description
The model A2G-20 air velocity meter is used for measuring flow rates of gaseous media in ventilation and air-conditioning applications. In addition, the A2G-20 features integrated temperature measurement.
Electrical output signals for both measurands (DC 0 … 10 V or 4 … 20 mA; adjustable at the instrument via jumpers) enable the direct connection to control systems or the building automation system.
An additional switching output enables a flexible operation for controlling further components of a ventilation and air-conditioning system.
The LC display and the clear menu navigation enable a time-saving and simple commissioning.
#Dial#thermometers work on the #bimetal, #expansion or gas actuation principle. This enables scale ranges of -200 to +700 °C in different class accuracies, response times and resilience to environmental influences. Diverse connection designs, stem diameters and individual stem lengths enable a flexible measuring location design.#Dialthermometers with remote capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.
