Probe tube with heated miniature thermistor for flow measurement |
FV A645 TH3 Thermoanemometer
Type
¡Ü Probe
tube with heated miniature thermistor for flow
measurement and highly precise Ni10 temperature sensor for temperature compensation.
¡Ü Evaluation
electronics are located in a separate module
housing.
¡Ü
Measurement modules can be directly plugged
onto the
measuring instruments.
¡Ü
Particularly suitable for low wind velocities, e.g. for
draught measurements at work places.
¢Ñ When attaching the measuring module
other input
sockets will be blocked. If the blocked input sockets need
to be used or if the module can be directly installed at
the measuring location, an extension cable ZA 9060-VKx
(maximum length 5m) must be used.
Accessories:
ZA9060VK2 |
Extension cable 2m long |
ZA9060VK4 |
Extension cable 4m long |
