Probe tube with heated miniature thermistor for flow measurement
FV A605 TA Thermoelectric
Flow Sensor Type
● Probe
tube with heated miniature thermistor for flow
measurement and precision NTC resistance for measuring the ambient temperature
and automatic compensation. ● Evaluation
electronics are located in a separate sensor transmitter module. ● High
accuracy as a result of integrated temperature
compensation and individual calibration in wind tunnel, with laser Doppler
anemometer as reference system. ● Response
time only 2s for smoothing the measured value indicated, optionally without
smoothing with 100ms response time. ● Suitable
for measuring small flow velocities in gaseous substances, particularly
for control systems and monitoring. ● Typical
applications include comfort index measurements, HEVAC applications, environmental
technology, clean room technology and process measuring and control technology.
▒ A special connector cable allows to connect the flow
sensors to all ALMEMO® multi-purpose devices, data
loggers and data acquisition systems. For volume flow
rate measurements the cross section of the ventilating
shaft can be easily entered into ALMEMO® devices. A
problem-free averaging is then possible.
