THE MAXIMUM INTRINSICALLY SAFE INPUT PARAMETERS ARE AS FOLLOWS:
Ui = 24V dc
Ii = 50 mA
Pi = 0.3W
THE EQUIVALENT PARAMETERS ARE:
Ci = 0
Li = 0
SPECIAL CONDITIONS FOR SAFE USE:
1. Temperature Class of the BDI sensor is marked as Tx, since the surface temperature is controlled
by the process temperature being monitored. The sensor itself exhibits negligible temperature rise.
2. When located in an area requiring EPL Ga / Category 1G (e.g. Zone 0) hazardous area, the user
shall ensure that electrostatic charging of the non-metallic parts cannot occur.
3. When provided with terminations by means of flying leads, these shall be terminated in an
appropriately protected terminal box.
4. When installed, the BDI strip shall be provided with an IP rating of IP20 as a minimum.
5. For Group I applications, the BDI strip and terminations shall be protected to IP54 or better.
