Before starting the installation, check the following:
- Make sure that your installation site suits
the Ex classification of the probe: for classification information relevant to your region,
see Regional Ex certification overview.
- Review the hazardous area information
relevant to the Ex certification in your region and make sure that the conditions for
safe use are met.
- Review the wiring diagram (Figure 1) for power supply requirements: MGP260 probes require a dedicated 18–30 V DC power
supply. Note that in addition to the power supply input for the probe, each analog output
must be externally powered.
- Review the information in Pressure compensation input options and make sure that you
are using a pressure compensation input source that matches the settings of your MGP260
probe.
- Inspect the probe for any possible damage
or dirt that could compromise the leak tightness of the device (for example, bent or
punctured parts of the probe body, or dirt that prevents the connection box from closing
fully).
- When selecting the cable glands and plugs for your application, make sure they are Ex
compliant.
- If you install MGP260 to the process using a ball valve, note that it is necessary to use
a 2" ball valve and a reducer in order to accommodate the probe head (diameter 1.57").
- Note that installing MGP260 series probes
into pipes with condensing gas and intermittent flow is not recommended. When the probe is
installed into a pipe with condensing gas, it is typical for the probe to require some time
to heat up and recover from condensation.
| The NPT threads of the probe can have sharp edges. To
avoid injury when touching the threads, wear protective gloves. |
| The probe can cause a foot injury if
dropped. To avoid foot injuries, wear protective shoes. |
