Sensors of Humidity compatible with Labview ??

[Semou95]

Hey,

I'm looking for sensors of humidity compatible with labview ans my comfiguration.

I have a PCI-6013 and a CB-68LP and I´d like to mesure humidity in an air-conditioning.

Can you help me I´would like to know which sensors could I use.

Thank You very Much

Any sensor with an voltage output conditioner will do the job.

We use rotronic HYGROCLIP.

If price matters, have a look at the sensirion sensors with digital output, they will use the DIO lines but need more software written.

Hi,

there are humidity sensors from Testo ...

Ex: testo602 on RS-232: 4800,N,8,1
- you send J1 you have the humidity
- you send J2 you have the temperature
- you send J3 you have the dew point ...

In LabView, LabTab/Excel or anything, it is easy to get the measures
....

Although use this configuration 4800,N,8,1 there is not any data coming from the testo humidity sensors.

I`m using the testo 400 with 2 channels, I downloaded from the Testo webpage a kind of code, but; they don`t work with the serial port,and if i try to use the Labview example of receiving and sending signal from the serial it doesnt show anythin??

Any ideas??

first try to use this with hyperterminal.

and check if you have the right serial cable !

I already check the cable, it is a RS232, I try to set a conection using hyperterminal, but nothing comes from the serial port.

A long time ago I was working with sartorius balances, and in that time at the beginning I was getting strings of unreadable characters of ASCII code, after I read some posts  I just had to set the parameter in the string code and started working.

For me, someting related to the format flow in Testo sending data is not right.

Hi

If also hyperterminal does not work, try another type of serial cable.

basically 2 types and a lot of subtypes exist.

The two types are straight and twisted, where twisted normally is called a null modem cable.

This one works when both systems use the same pins to send and the same to receive data.

Hello again, recently i found in the Indian Testo website http://www.testo.de/online/abaxx-?$part=PORTAL.IND.Applications&$event=show-from-content&externalid=... some code for many applications, one of them was for Labview.

Something different is in the approach that they use, they don`t work with the serial port, instead of that; they use the properties node and the invoke node. I downloaded and when I try to run them, they seem to be broken.

I`m not an expert, but when I try to fix them nothing seems to work, where did they find these invoke nodes?????

Have you installed toolbox?

I have tested the program labview with Testo 350 M/XL testo 454, it works for the control unit and 2 loggers, but not for analyzer box.

I installed the toolbox, but still I have to work in the *.DLL files, because in the opening of the automatition from the Activex show me the error -2147467263 related to general problem, I think I`ll search in the VB code to see why the error..
