从全球市场供应商批量进口O2i Flex Oxygen Sensor Interface Board Ikoj

O2I-Flex Oxygen Sensor Interface Board FEATURES * Provides the electronics necessary to power and control SST's range of zirconium dioxide (ZrO2 ) sensors * Externally triggered automatic or manual calibration. Calibration can also be initiated via an on-board push button * Power and sensor operating LEDs * Removable polarised screw terminals for easy wiring BENEFITS * Adaptive software filtering provides a fast sensor response coupled with a stable oxygen output * High accuracy linear output * Can be calibrated in fresh air (20.7% O2 ) or in any other known O2 concentration TECHNICAL SPECIFICATIONS Supply voltage 24V DC ± 10% Supply current 600mA max. at 24V DC Digital output RS232 Analogue output 4 ~ 20mA; load 100 ~ 600Ω or 0 ~ 10V DC ; load 10kΩ min Temperature limits Storage: -10'C to +70'C Operating: -10'C to +70'C Oxygen pressure limits 1 ~ 1000mbar OUTPUT VALUES Oxygen range (analogue output) 0.1 ~ 25% O2 or 0.1 ~ 100% O2 Oxygen range (RS232 output) 0.1 ~ 100% O2 Accuracy after calibration 1% O2 Repeatability after calibration 0.5% O2 Output resolution: 0-10V DC : 0.01V 4-20mA: 0.01mA RS232: 0.01% O2 Response time (step 10-90%) Fast response sensor connected: < 4s Standard response sensor connected: < 15s Initial warm up time (till stable output) 5 ~ 10mins Output inactive start up delay (heater warm up) 60s
