GE德鲁克(Druck) 宽温度范围压力传感器 PDCR 9x2

PDCR 9X2 - 06/95 cd PDCR 9X2 WIDE TEMPERATURE RANGE TRANSDUCERS The PDCR 9X2 type pressure transducers are based on the same design format as the general purpose PDCR 900 series, but configured specifically for operation outside the standard -20° to +80°C temperature range and provide high thermal performance over the operating temperature range. Type Number and Specification PDCR 902 - Basic core PDCR 912 - General purpose PDCR 922 - General purpose PDCR 932 - Waterproof/Depth PDCR 962 - Integral connector The type numbering system denotes the following details: PDCR 9 X 2 Compensated temperature range -54° to +125°C Backend construction & electrical connection e.g. 1:integral vented cable and boot 900 transducer series Please refer to ordering information, assembly diagram and installation drawings to fulfil your requirements.

Other pressure units can be specified, e.g. psi, kPa, mH20. For higher ranges refer to PDCR 330 data sheet. Excitation Voltage 10Vd.c. regulated to within ±0.1% at 5mA nominal. Other regulated d.c. excitation levels can be specified e.g. 5V d.c. giving proportionally reduced output span. Output Voltage 50mV for 350mbar range 100mV for 700mbar range and above. The above outputs are for 10 Volts d.c. regulated excitation voltage. Common Mode Voltage Typically +6V to +8.5V with respect to the -ve supply at 10V d.c. excitation. Operating Temperature Range -54° to +125°C. N.B. It is possible to operate PDCR 912 and PDCR 932 types with pressure media temperature between -54° to +125°C, however the vented cable and moulded termination must be limited to -20° to +80°C operation. Temperature Effects Total error band (T.E.B.) or average coefficients (% F.S./°C) including thermal zero shift, sensitivity shift and the thermal hysteresis (for ranges 700mbar and above): -54° to +125°C: ±2.5% T.E.B.; ±0.015% F.S./°C Improved performance e.g. 0° to +50°C: ±0.3% T.E.B.; ±0.006% F.S./°C -40° to +80°C: ±1.0% T.E.B.; ±0.008% F.S./°C -54° to +125°C: ±1.5% T.E.B.; ±0.009% F.S./°C N.B. The temperature effects are applicable when excitation voltage regulated as stated. Sensitivity shift with be affected typically 0.004%/reading/°C per 1% change in excitation voltage. For additional specification including assembly diagram and installation drawings please refer to PDCR 900 SERIES data sheet.
