OXY-LC Oxygen Sensor Interface 0.1-25% Oxygen Range High accuracy

OXY-LC  Oxygen Sensor Interface 0.1-25% Oxygen Range High accuracy   GENERAL DESCRIPTION: The OXY-LC Oxygen Sensor Interface provides all necessary electronics to power and control SST Sensing’s range of dynamic oxygen sensors.   Calibration, or re-referencing, is required when a sensor is attached to the interface for the first time. Regular calibration removes any sensor drift that may occur during the first few hundred hours after a new sensor is connected. For maximum accuracy in the range 0.1 to 25% O 2 it is recommended that a calibration to 20.7% O2 should occur every time the sensor is known to be in fresh air (20.7% O 2 takes into account typical humidity levels). A software delay prevents calibration from being completed before the sensor has been in ON mode for 5 minutes. If a calibration is initialised during this delay the unit will calibrate after the 5 minutes have elapsed.   SPECIFICATIONS: Electrical Supply Voltage : 8-28V DC (RS485 Variant) 20-28V DC (0-10V DC and 4-20mA variants)   Current consumption : Varies with Supply Voltage, typical 600mA max @ 24V DC,  1.2A max @ 12V DC   Temperature limits : Operating  -30 to 70℃ Storage  -40 to 85℃   Operating pressure limits (Sensor and interface for correct barometric pressure compensation)   Pressure : 260 to 1260mbar absolute   PERFORMANCE CHARACTERISTICS:     ELECTRICAL CONNECTIONS:                    Welcome to your inquiry!
