Welcome to this tutorial.
Your are using our Monitoring System RMS and you have the HF520-EX ATEX transmitter running with RMS-ADC-L-R. Now you want to be alerted if the probe is screwed off.
The value for the probe loss should be at least 50 °C above the maximum possible measured value. In this example, it is possible that 150 °C is measured.
Now you get the correct measurement. And if the probe will be removed, then you will get the defined value of probe loss, in this case 200:
You can now set an alarm scheme for 199 °C with an e-mail alert for example.
If have any questions, please do not hesitate to ask.

- Use AC3006 cable and connect HF520-EX with HW4 while it is connected to RMS-ADC-L-R.
- Go to Device Manager and change the range of analog outputs for temperature. Use a value for upper limit as described obove. In this example the range -40 to 200 is set:
- Then go to Settings and change the value "Generate fixed humidity value" to 100 (the normal maximum humidity you have) and "Generate fixed temperature value" to the value for probe loss, in this example 200:
IMPORTANT: only set the flag "Generate fixed values when probe connection is lost", remove the other two flags. - Save with OK.
- Go to RMS. Go to Tools / Setup / Devices. Select your RMS-ADC-L-R and choose option / read out device settings:
- Then show properties. Keep the range from Input Scale 1 0-100 (your humidity range). Change the rage of Input Scale 2 -40-200 (Measurement range high with the value from HW4, 200 in this example). Both Input range 4..20mA.:
- The flags "Openloop detection" and "Threshold Tracing" are useless in this situation. Save with "Apply".
Now you get the correct measurement. And if the probe will be removed, then you will get the defined value of probe loss, in this case 200:
You can now set an alarm scheme for 199 °C with an e-mail alert for example.
