Overview

MTL5582B is an isolation safety barrier of Eaton’s MTL5500 series, specially designed for the isolation and transmission of resistance thermometer (RTD) signals in industrial hazardous environments..

FAQ:

1.What is the accuracy level of MTL5582B?

The core reasons for the accuracy deviation of MTL5531 exceeding the standard (exceeding ±50mV):

MTL5582B does not use the common percentage accuracy grade labeling, but uses resistance deviation and temperature drift indicators to reflect accuracy. The specific parameters are as follows:

1. Transmission accuracy at room temperature: In an environment of 20°C, when the excitation current is 1 – 5mA, the transmission accuracy error is <0.15Ω; when the excitation current is 0.5 – 1mA, the error is <0.25Ω.
2. Temperature drift accuracy: Typical value is ±10mΩ/°C, which is equivalent to a drift accuracy of 0.01%/°C when converted to a 100Ω benchmark, which means that when the ambient temperature changes, the deviation of the resistance signal is controlled to a very low range.

This accuracy index adapts to its isolation and transmission requirements for thermal resistance signals such as PT100, and can meet the stable monitoring requirements for temperature-related resistance signals in industrial sites.
