Connecting an OMEGA HHP8200 Manometer to Labview through USB

[yoshable]

Hello, 

I'm a student at Drexel Unvierstiy and for our senior design we have the measure the flow rate of some fans and we plan on using the HHP8200 manometer for our pressure readings and feeding that output into calculations in LabView. I'm aware what the code should be moving forward once the sensor is connected, but I'm unsure how to actually get the data to feed into LabView from the manometer. We also have an OMEGA HH311 psychrometer that we will need the sensor data from. Any help will be appreciated. 

Thanks!

Hi yoshable,

the HHP8200 provides a

RS232 Output with Optional Software

according to Omega's website.

You can use VISA functions to communicate with devices over RS232.

The same applies to that HH311…

I'm still having trouble actually getting values out of the manometer into useable data in LabView. I've gotten some VISA blocks that I've been looking through but none of them actually let me connect an input. What blocks should I be using in order to get raw data off the manometer, through VISA, and into useable values?

Hi yoshable,

what have you tried? Where's your VI?

What blocks should I be using in order to get raw data off the manometer, through VISA, and into useable values?

You need to configure a serial port: VISAConfigureSerialPort.

You need to read data: VISARead.

In case you need to send commands: VISAWrite.

To parse the received string data: manual of your device with description of data format…

As long as you write about "blocks" you should take the online courses to learn LabVIEW, offered in the header of this LabVIEW board!
