E-HELP: Concentrating Temperature Readings with the NCS

E-HELP: Concentrating Temperature Readings with the NCS
Q: I want to transmit temperature readings from 44 different four-wire RTDs over MODBUS using your TMZ PC-Programmable MODBUS Temperature and Signal Transmitter. Can I use the EMM Ethernet/MODBUS Interface Module of the NCS NET Concentrator System® to concentrate the outputs of the TMZ? I would like to have the EMM configured as a MODBUS RTU Master and the TMZs as MODBUS RTU Slaves and then output from the EMM as a MODBUS/TCP to my control system. Can this all be done?

Temperature Q&A with J.R. Madden: Accurate Differential Temperature Readings

Temperature Q&A with J.R. Madden: Accurate Differential Temperature Readings

Q: How do I measure differential temperature very accurately?

A: Whenever accuracy is the goal you want to start with RTDs (temperature range permitting). Many temperature transmitters will accept two RTDs and output the difference between the two inputs. However, if you look closely you will find they only make 3-wire RTD measurements and you may have errors and drifts due to wire length and corrosion build up over time.

NCS NET Concentrator System Improves Efficiency and Performance of Power Plants

NCS NET Concentrator System Improves Efficiency and Performance of Power Plants

Performing maintenance, repairs and upgrades at modern power plants is often challenging. Many power plants are built on instrumentation from companies that no longer exist or that use technology that has become outdated. Updating plants with new technology that can improve performance and reliability can be challenging and cost-prohibitive.

Moore Industries has a full range of instrumentation that can help power plants manage their transition to modern technology. One product detailed in our Automation and Instrument Solutions for Power Plant Applications line card is the NCS NET Concentrator System®.
