Technical Datasheet
Sensor Cap

Part No. U002-01

Description

Each sensor cap has a unique identification number and is used to measure the environmental
conditions (temperature and relative humidity) during stability testing and monitoring /mapping
applications. The cap incorporates the Rotronic Hygromer humidity sensor with Airchip 3000 housed
within a plastic casing and containing a dsub connector for connectivity to the logger cap.

The sensor cap is fitted to a test chamber (U011-01) during stability testing and a stand (U010-01)
during monitoring applications. A logger cap (U001-01) containing the test settings is attached to the
sensor cap. The logger cap collects and stores the temperature and humidity readings and transmits
the data wirelessly to the Amebis Control Software.

The sensor cap is supplied with a calibration certificate traceable to SCS (Swiss) or UKAS (UK). The
sensor cap can be calibrated and adjusted using the calibration cable (U012-01) and the Rotronic
HW4 software.
