Get the Most Out of Your HART Devices

Get the Most Out of Your HART Devices

A study by the ARC Advisory Group in 2011 showed that 46 percent of all field devices installed worldwide communicate using the HART protocol. This is more than all fieldbus devices, proprietary protocols and 4-20 mA (analog/non-smart) combined. There’s a good chance that you are have HART-enabled devices in use at your plant or off-site location. The question is: are you getting the most from HART?

Moore Industries Technology Reduces Legwork at Pulp and Paper Site

Moore Industries Technology Reduces Legwork at Pulp and Paper Site
State regulations required a major pulp and paper company to monitor and record daily effluent water rates. This requirement was being fulfilled by sending an employee from their main control site to a remotely located pond three times a day to manually record water levels. This process was inefficient, time-consuming and didn’t provide them with real-time data.

E-HELP: Differential Temperature Measurement with Two RTDs

E-HELP: Differential Temperature Measurement with Two RTDs

Q: I am looking for a differential temperature transmitter. We have used the SPT in the past and know that it will work, but I don’t know if you can use two inputs of two different 4-wire RTDs with the SPT.

A: The SPT has only four input terminals; therefore the number of RTD wires is limited. For differential temperature one RTD can be a 3-wire and the other RTD can only be a 2-wire. The lead length compensation wire of the 3-wire connection compensates for the lead length of both RTDs. This is only useful if you make sure that all five wires have the identical resistance.

The HCS as a Diagnostic Tool

The HCS as a Diagnostic Tool

We know it is easier for many customers to communicate using MODBUS RTU protocol than HART protocol and that makes the HCS HART® Concentrator System a very popular tool.

We also know customers want more diagnostic information so they can access the health of their processes and instrumentation. HART Command 48 is what the industry and the HCS uses to retrieve diagnostic information from the HART slave device, whether that is a transmitter or a valve positioner. The HCS will not implement Command 48 unless you turn on that feature by checking “Acquire Additional Status” on the HART tab of the configuration software.
