Application:- Analysis technology- Safety circuits in vacuum systems- Control of ionization vacuum meters- General pressure measurement and control in systems in the fine and coarse vacuum range
Measurement principle: Heat conduction according to Pirani
Measurement range (Air, O2, CO, N2): 5×10^-4 … 1000 mbar
Accuracy (N2): 1×10^-3 … 100 mbar ±15% of the measured value
5×10^-4 … 1×10^-3 mbar ±50% of the measured value
100 … 1000 mbar ±50% of the measured value
Resolution: 1% of the measured value
Repeatability: 1×10^-3 … 100 mbar 2% of the measured value
Output signal (Measurement signal)
Voltage range: 0 … +10.3 VDC
Measurement range: +1.9 … +10.0 VDC
Voltage-pressure relationship: Logarithmic 1.286 V/decade
Error signal: 0 … +0.5 V (filament break)
Output impedance: 2×4.7
Minimum load impedance: 10 k, short-circuit proof
Response time: 80 ms
Transmitter identification: 27.0 k, against supply ground
Adjustment: One button for ATM and HV adjustment
Switching function: SP1, SP2
Threshold display and setting: One button for threshold output at the measurement signal output. Setting occurs with prolonged or repeated pressing
Setting range: 2×10^-3 … 500 mbar
Hysteresis: 10% above the lower threshold
Relay contact: 30 V, 0.5 ADC, potential-free
Closed: at low pressure (light on)
Open: at high pressure, error, missing supply
