Page 15: Product Description
Product description 3 Product description 3.1 Function The gauge has a Pirani sensor and a capacitive diaphragm sensor. Both sensors are always active. For low pressures, the unit only uses the signal from the Pirani sensor for the pressure measurement. For high pressures, the unit only uses the signal of the capacitive diaphragm sensor. In a mixed range, the unit weights both signals proportional to the pressure and determines the output signal on this basis. -
