Re: TC08 and druck pressure transmitter

Peter, Thanks for that comprehensice reply -- but there is still a problem. I have checked the supply and the connections and switched on, it reads 0.48 ( I was expecting 1.0), now pressurising or pulling a vacuum does not nudge this figure. Everything here is tried on three units with the same resu...

Re: TC08 and druck pressure transmitter

Peter,

I have spoken to Druck expecting individual callibration sheets but they tell me that the info required is on the unit itself, and it is this:

Range; 2.5 bar a
Output: 4 to 20mA
Supply: 9 to 28Vdc

Can you please let me know how to deal with this?
thanks

Re: TC08 and druck pressure transmitter

Firstly, we need to positively identify the operating pressure range of the sensor. Is it "Relative" or "Absolute" pressure and what is the full scale? For example:- Relative pressure sensor would be:- 0 mbar at ambient pressure -1000 mbar at full vacuum Absolute pressure sensor would be:- 0 mbar a...

Re: TC08 and druck pressure transmitter

Peter, I have gone through this again exactly as you indicated and am still not getting a result. When I picked the channel I left it on thermoK. I later tried this with mv and the only difference it made was to show a negative value. It makes no difference on whether the sensor is or is not plugged...

Re: TC08 and druck pressure transmitter

thanks for this Peter If you are using the PTX1400 sensor which is a two pin, 4-20mA device, then you need the following connections and settings:- A power supply for the sensor of at least +15V DC & up to +28V DC. Connect the +Ve output of the PSU to pin 1 of the sensor. Connect pin 2 of the sensor...

Re: TC08 and druck pressure transmitter

I would expect the output, pin 3, to be connected to the terminal board not the power supply pin. I'm using a PTX1400 http://www.cuthbertsonlaird.co.uk/pdf/Druck_PTX1400.pdf not a PMP1400 http://docs-europe.electrocomponents.com/webdocs/0114/0900766b8011430a.pdf and the way I read it is that pin3 i...

Re: TC08 and druck pressure transmitter

DSCF5144a.jpg thanks, I have the terminal board pin1 to the 4-20/5V and pin2 to COM, and set a tc-08 channel to mV but am getting zero reading that does not seem to alter with pressure. Do I need to calibrate this somehow? As I said before -- I have inherited these transducers as is, and they behav...

TC08 and druck pressure transmitter

I have inherited an incomplete hardware and software set to conduct an experiment. I have managed to set up the thermocouples to capture the temperature points successfully but am stuck as to how to use the druck ptx1400 pressure transmitter to read a low vacuum. The set of bits is not likely to be ...

display in real time

just acquired a tc-08, and using a sony vaio laptop.
how do i display the readout in real time graphically on the screen?
thanks.
