APPLICATIONS
The ROTRONIC XB OEM-Series of temperature and humidity transmitters is designed exclusively for the OEM market using the latest
AIRCHIP3000 technology. Digital signal processing significantly benefits humidity measurement in the following key areas:

Environmental Chambers Industrial Process Monitoring Environmental Test Drying processes

Measurement accuracy
Digital processing of the sensor signals by the XB OEM transmitters provides more scope and greater flexibility when compensating sensor
characteristics such as linearity and temperature compensation. The ROTRONIC HYGROMER® capacitive sensors have always been the
leader in both precision and stability. With the application of digital technology, sensor performance is now further enhanced.
Calibration
Calibration and sensor data are retained permanently within each XB OEM transmitter. Software-based calibration is simple and precise;
there are no hard to reach, hard to adjust potentiometers. Multiple calibration points can be selected across the full measurement range.
Transmitters of the XB OEM-series are primarily used in environmental chamber applications that require highly accurate humidity
measurement.
Field Service made easy with the XB OEM-Series
On-site validation and maintenance of the sensors is made simple with the XB OEM transmitters.
Use a Hygropalm handheld HP22/HP23 instrument and service cable to perform the following:
• Display of the % Relative Humidity reading from the transmitter on the Hygropalm HP22/HP23
• Single point calibration of the transmitter using a reference probe attached to the HP22/HP23
• Single and multipoint calibration of the transmitter against a known reference environment
Applications
Many manufacturers of environmental chambers have chosen the ROTRONIC XB OEM transmitters. Additional applications are dryer
cabinets for clothes, complex climate controls in pasta machines, process-drying and many more.

THE OUPUTS OF THE XB OEM TRANSMITTER SERIES

The high flexibility of the XB OEM transmitter allows customer using ROTRONIC HW4 software to choose the output signal (0…1V, 0…5V,
0…10V, 0…20 mA, 4…20mA) and freely scale it with the HW4 ROTRONIC software, to any value up to the probe limits. Dew-/frost point,
Pt100 RTD direct outputs optional available.
