Frequently asked questions (FAQ)
What is the difference between the PRP and HT versions?
The PRP (Poison Resistant) version has increased sensor resistance to substances that poison the catalyst, while the HT (High Temperature) version is designed to operate at elevated process temperatures.
What wiring does Series 47K work with?
The sensor is available in 3-, 4- or 5-wire versions, allowing it to be matched to the existing installation and the type of control panel.
Does Series 47K meet SIL requirements?
Yes, the sensor has a SIL 2 safety integrity level, allowing it to be used in functional safety systems.
