ESMI52051RE / FFS06710612, Thermal RoR, Schneider Electric

The ESMI 52051RE is analogue addressable sensor employing low mass thermistors and microprocessor technology for fast response and linear temperature sensing. It provides an alarm when the rate of rise in temperature exceeds 10°C/minute (typical) or if the temperature exceeds a threshold of 58°C (Response Class A1R).
