Hello Забери билет от Гос.Лото,
In this month's newsletter we explore how Moore Industries products and solutions can help ensure loop integrity and improve temperature measurement accuracy/stability to provide process reliability and save you money.
Isolators in a Cabinet in a Class I, Div 2 Location
Many process facilities require transmitter and analyzer signals be shared with Basic Process Control Systems and backup/secondary systems. Ensuring the primary control system will continue to receive these process signals if a backup system fails is a top priority. This type of loop integrity can be achieved by utilizing an area isolation approach with Moore Industries ECT family of isolators, available in narrow sizes when cabinet space is an issue.
When significant temperature measurement errors were falsely activating a safety deluge system and destroying expensive production batches at a nutritional supplement process facility, Moore Industries had the solution, applying the advanced features of the TDZ3 Dual Input Smart HART Temperature Transmitter: LOW SELECT, CORROSION DETECTION, BACKUP/FAILOVER and ALLOW DROPPING.
TRX and TRY
Moore Industries TRX & TRY PC-Programmable Temperature Transmitters deliver superior reliability and program in a minute or less to convert a multitude of inputs into highly accurate 4-20mA outputs that are both linear and scalable.
Improving Long Term RTD Temperature Measurement Stability
Utilize Class A, 4-wire RTDs that are no longer cost-prohibitive to eliminate potential measurement errors created by resistance imbalances between lead wires. Make sure they have been thermally aged to further improve their long term measurement stability.
