The enhanced display models, with standard loop-powered backlight, let the user see the display under any lighting condition, and present valuable information such as the process variable, input type, engineering units, and bargraph. The display can be configured to show the PV, mA output, or %. These models are housed in a sleek & rugged die-cast NEMA 4X enclosure that is available in general purpose and explosion-proof versions. The enclosure has two ½" NPT conduit holes, and one ½" NPT process sensor connection port for probe or adaptor fitting. Non-standard models with other conduit hole and process opening sizes are available, see the ExSense Builder. For remote mounting applications the PD310 may be ordered without the process sensor connection port.
The ExSense packaging lends itself for duty in harsh environments. The good looking die-cast aluminum NEMA 4X housing affords serious protection from the elements, impact damage, corrosion, and electrical interference; it is also explosion-proof. It can be installed almost anywhere. The display models have very flexible installation options. The built-in mounting ears allow for wall, or pipe mounting, and include a rotatable meter. All ExSense systems can be also surface mounted via the thermowell.
PD312 HART Transmitter & Remote Display
In this application the PD312 HART Explosion-Proof Temperature Transmitter is being powered by the PD6000 dual-scale meter; the meter displays the temperature on the top and the mA current on the bottom display. A PLC, DCS, or other devices could be connected in the loop as shown. The 250 ohm resistor is the minimum loop resistance needed for HART communication with a HART modem.
