Detailed Product Description
FA 300 Ex may only be used in connection with approved sensor feeding instruments or safety barriers or galvanic separating
The CS dew point sensor FA 300 Ex provides reliable and long term stable dew point monitoring in applications where explosive gases can occur from time to time or permanently. It’s approved for use in explosive areas of zone 1. II 2G EEx ia IIC T4
FA 300 Ex may only be used in connection with approved sensor feeding instruments or safety barriers or galvanic separating elements with max.:
U0 = 30 V max.
I0 = 100 mA max.
P0 = 1 W max.
The measured dew point is output via a 4-20 mA signal output (loop powered).
