INTRODUCTION
The ExSense T Series is a line of smart temperature transmitters that include some models with HART¢ç communication capability. All even numbered models can be configured using a HART modem and a PC running the free HART software provided, or they can be configured in the field using a handheld HART communicator. The other models can be configured using a USB modem and a PC running the free software provided. All enclosed models can be ordered with an integral Pt100 RTD, J, K, T thermocouples; see the Ordering Information for model numbers.
PD310 & PD312 Enclosed Display Models
The standard loop-powered backlight display lets the user see the display under any lighting condition. The PD310 & PD312 are housed in a sleek & rugged explosion-proof NEMA 4X enclosure with two 1/2", 3/4", or M20X1.5 conduit holes, and 1/2" or 3/4" NPT process sensor connection port (for probe, thermowell, or adaptor fitting). For remote mounting applications the PD310 may be ordered without the process sensor connection port. The backlit LCD provides the user with valuable information such as the process variable, input type, engineering units, and bargraph. The display can be programmed to show the PV, mA output, or %. Both models are available with safe area (NEMA 4X, IP66 rated), or Certified explosion-proof enclosures.
PD310 & PD312 HART Programming
PC Programming Software
The Current Setup window is used to trim the analog output to match the device reading the current.
Click on Read and type the values in the boxes. Click on Update to upload the new values to the transmitter.
Test your loop by selecting a Fix Loop value and clicking Send.
The Parameter Setup window is used to set up the input type, range for the 4-20 mA, temp units, and other settings related to the sensor and analog output. You can also select to display PV, mA, or %.
The HART Information window allows you to program or read the transmitter information and to modify the HART address.
The Graph Monitor window is used to monitor the PV, mA, and %. You can also monitor just one of the variables.
A log data file can be saved for later viewing; it contains the time, data value, and units. The screen update rate is selectable between 2 sec and 30 min.
In this application the Smart 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 or a HART communicator.
