Safety Integrity Level (or SIL) refers to a system introduced by the International Electro-technical Commission (IEC) to help operators quantify safety performance requirements of various instruments for hazardous applications. The high-speed thermocouple transmitter is SIL2 certified, making it suitable for hazardous applications requiring a SIL2 certified transmitter. The MTP300i-SIL-K SIL2 approved thermocouple transmitter accepts and converts various thermocouple types, to a galvanic isolated 4-20mA output. These transmitters can be installed in zone 1 or 2 with the “n” protection type (IEC/EN 60079-15).
