Page 4: Safety Precautions
PU/PI and PS10 Instruction Manual Safety precautions 1.1 Appropriate use In addition to differential pressure data, the PU/PI and PS10 differential pressure transducers also record positive and negative overpressures. Always observe the operating requirements—particularly the permissible supply voltage—indicated on the rating plate and in the "Technical data” section of this manual. -
Page 5: Symbols
PU/PI and PS10 Instruction Manual The electronic components of the instrument contain environmentally hazardous materials and materials that can be reused. For this reason the instrument must be recycled in accordance with the environmental guidelines of the jurisdiction in question once it has been taken permanently out of service. 1.4 Symbols The symbols given below are used throughout this manual to indicate instances when improper operation could result in the following hazards:... -
Page 6: Instrument Description
PU/PI and PS10 Instruction Manual Instrument description The PU/PI and PS10 pressure transducers are pneumatic, electronic sensors for measuring overpressures, vacuum pressures and differential pressures. Typical applications include, for instance, pressure measurements in air-conditioning and ventilation ducts. At the heart of the transducer is a pressure measurement capsule with a beryllium bronze membrane spring, which is displaced by the pressure difference between the two chambers of the measurement capsule. -

Page 8: Calibrating The Zero Point
PU/PI and PS10 Instruction Manual Display-connector Calibrating the zero point Please remember that it takes roughly 30 to 60 minutes for the pressure transducer to warm up after it is switched on. The output signal may not remain stable during this period. It is recommended that the zero point after a long operating time (approximately 6 months) is checked and if necessary calibrate it again. -
