WaterLOG® H-310 Submersible Pressure Transducer Specifications (page 1) Accuracy (Maximum percent of error in measurement) Pressure: Less than or equal to 0.02% of full scale output (FSO) over temperature range referenced to a straight line stretched from zero psi to maximum pressure. Temperature: Internal temperature ±1°C over temperature range Resolution (Smallest change detectable in output signal) Pressure: 1 part in 250,000 (0.0004%) Temperature: 1 part in 250,000 (0.0004%) Linearity Less than 0.02% deviation from a straight line referenced to end points Pressure Hysteresis Less than 0.01% of FSO Long-term Stability Accuracy drift is less than ± 0.05% of FSO per year Response Times SDI-12: 8 second measurement sequence (programmable 2 second "fast measure") RS-232C: 8 second measurement sequence Standard Ranges Pressure Depth Accuracy 0 - 15 psi 0 - 34.6 ft. ±0.007 ft. 0 - 30 psi 0 - 69.20 ft. ±0.014 ft. Custom calibration ranges available from 5 to 75 psi Pressure Overload Less than 2 times the rated pressure Environmental Restrictions Operating range: 0 to 40oC (non-freezing) Compensated range: 0 to 40oC Storage: -10 to 75oC Environment Humidity: 90% non-condensing Temperature Range:     Operating: -20 to +50oC (-40 to +122oF)   Storage: -55 to +75oC (-67 to +167oF) Media Compatibility Liquids and gases compatible with PVC, RTV and stainless steel Pressure Port Stainless steel screen with 149 micron filter, field replaceable Dry Air System Prevents moisture from condensing in the submersible pressure transducer, provides compensation for changes in atmospheric pressure without impairing the sensor's accuracy. Power Supply Voltage: 9.6 to 16.0 Volts DC Supply Current:     Sleep Mode: 1mA maximum   Active(measuring):  50mA maximum (Specifications continued) WaterLOG® H-310 Introduction WaterLOG® H-310 Specifications page 1 WaterLOG® H-310 Specifications page 2 Download PDF File (266kb)
