Product Information
XEN-TCG3880 Thermal Conductivity Sensor Short description
The XEN-TCG3880 is a thermal conductivity gauge (TCG) made using silicon technology. The sensor chip consists of a silicon rim of 2.50 x 3.33 mm, 0.3 mm thick, in which a silicon-nitride membrane is created. In the center is a heater, with a sensor element measuring its temperature. The chip measures the thermal conductance between the ambient and the center of the mem-brane, and this depends on several parameters, such as pressure, gas type, and material depo-sitions on the membrane. This dependence upon physical parameters allows the TCG to measure such quantities as absolute pressure, gas mixture composition, and material properties.
The standard housing for the XEN-TCG3880 is a TO-5 10-pins header, other housings are avail-able on request.
The XEN-TCG3880Pt has a class B Pt100 platinum temperature sensor on the TO-5 housing, next to the chip.
XEN-TCG3880 Thermal Conductivity Sensor Applications
