CS210 Enclosure Humidity Sensor
1. General
The CS210 Enclosure Humidity sensor contains an Elan HM2000 series precision
bulk-polymer relative humidity sensor. It is used to monitor the relative humidity
inside an equipment enclosure deployed in the field.
NOTE
The CS210 was once known as the 10162.
2. Specifications

The black outer jacket of the cable is Santoprene
compound was chosen for its resistance to temperature extremes,
moisture, and UV degradation. However, this jacket will
support combustion in air. It is rated as slow burning when
tested according to U.L. 94 H.B. and will pass FMVSS302.
Local fire codes may preclude its use inside buildings.
