AN Nuclear Fluid Temperature Sensor

AN Nuclear Fluid Temperature Sensor

AN sensor series are designed for measurement of pressurized or non-pressurized fluids, with a Platinum RTD sensitive element or thermocouple. They are particularly recommended for high pressure fluids and aggressive gaseous fluids for nuclear environments. AN sensors can also be used for any high pressure fluid temperature measurement.

Easy to install and maintain, these sensors are designed for harsh environment including nuclear ambient conditions.

The technology of sensitive element can be defined in compliance with the customer expectations: single or double RTD (3 or 4 wires) & single or double K type thermocouple. To ease maintenance, AN temperature sensor can be equipped with a specific connector in order to reduce the wiring and installation time on site.
