10162 Enclosure Humidity Sensor

1. General

The 10162 Enclosure Humidity sensor contains a Elan HM2000 series precision

bulkpolymer relative humidity sensor. It is used to monitor the relative humidity

inside an equipment enclosure deployed in the field.

2. Specifications

Sensor: Elan HM2000 series precision bulkpolymer

Relative Humidity Measurement Range: 0 to 100% non-condensing

RH Output Signal Range: 0 to 1.0 VDC

Accuracy at 25°C

unspecified (0 to 10% Relative Humidity)

±3% RH (10 to 90% Relative Humidity)

unspecified (90 to 100% Relative Humidity)

Typical Long Term Stability: Better than 3% RH per year

Response Time (at 25°C, 90% response): 1.5 minutes for a 30% to 90% RH

step change

Operating Temperature: 0°C to +50°C

Storage Temperature: -40°C to +80°C

Probe Length: 2.6 cm (1.02 in.)

Probe Cross Section Area: 0.6 cm x 1.1 cm (0.23 in. x 0.43 in.)

Power Consumption: <0.5 mA

Supply Voltage: 5 ±0.25 VDC

Settling Time: 3 minutes

3. Installation

Mount the 10162 inside the environmental enclosure using the mounting block

and the wire tie included with the sensor (Figure 1).

The black outer jacket of the cable is Santoprene® rubber. This

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.

4. Wiring

Connections to Campbell Scientific dataloggers are given in Table 1. The

probe is measured by a single-ended analog input channel.

5. Example Programs

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 10162 is measured using a single-ended

analog measurement (Instruction 1).

The probe output scale is 0 to 1000 millivolts for the relative humidity range of

0 to 100%. Table 2 provides calibration information for relative humidity.

6. Enclosure Humidity

Change the enclosure desiccant packs (model number DSC 20/4) when the

enclosure relative humidity exceeds 35%.

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. Spikes in the enclosure humidity are a

result of opening the enclosure door and allowing ambient air inside the

enclosure. The enclosure relative humidity will return its nominal values

(values before the enclosure door was opened) in approximately three to four

hours.

7. Maintenance

The 10162 does not have any user serviceable parts nor does it require any

routine maintenance.

Replace the 10162 probe every three to five years of continuous use. If the

probe fails, replace it with a new one.
