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.
