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 Sensor: Elan HM2000 series precision bulk-polymer Relative Humidity Measurement Range: 0 to 100% non-condensing RH Output Signal Range: 0 to 1.
CS210 Enclosure Humidity Sensor FIGURE 1. CS210 Installed on a CR1000 4. Wiring Connections to Campbell Scientific dataloggers are given in Table 1 and Figure 2. The probe is measured by a single-ended analog input channel. TABLE 1.
CS210 Enclosure Humidity Sensor 5. Programming This section is for users who write their own datalogger programs. A datalogger program to measure this sensor can be created using Campbell Scientific’s Short Cut Program Builder Software. You do not need to read this section to use Short Cut. The relative humidity signal from the CS210 is measured using a single-ended analog measurement (CRBasic instruction SEVolt or Edlog Instruction 1). The CR200 series and 21X use a control port to power the CS210.

Enclosure Humidity Change the enclosure desiccant packs (model number 4905) when the enclosure relative humidity exceeds 40%. Campbell Scientific recommends that all cable entry ports, that do not use a sealed bulkhead connector, be sealed with plumbers putty and that desiccant packs be placed inside the enclosure.
