F350 series sensors are versatile, high-performance air velocity and air temperature sensors with the sensor element built remotely from sensor electronics. Designed for products where segregation of the sensing element and electronics is desirable, such as products involving high EMI sensitivity or extreme temperature, or those where the sensing area is too small for typical probe-style sensors.
The sensor requires analog input option during RX3000 or U30 system configuration and use of a S-FS-CVIA when using the H22-001 data logger. When using a U12 data logger, this sensor requires an 0-5 Vdc analog input cable (CABLE-ADAP5) and external power provided by an AC adapter (AC-SENS-1).
