Sensor
HDL300 serieswater leveltransmitter pressure sensitive core adopts high performance silicon piezoresistive pressure filling core. The internal ASIC converts the sensor millivolt signal into standard voltage current or frequency signal which can be directly connected with computer interface card control instrument intelligent instrument or PLC. Current output mode can be used for distance transmission. The product is easy to install and has high anti-vibration and anti-impact performance. It is widely used in process control aviation aerospace automobile HVAC and other fields.Product name4-20mA output water level transmitter sensorKey words liquid level transmitterRange 0..1...2...5...8...10...100mH2OOverload Pressure 200% ;Transmission Distance 1Km(supply 24V)Acc. 0.5%FS 0.25%FSLong-term Stability Typical:0.1%FS/yearTemperature effect on zeroTypical:0.02%FS/ Max0.05%FS/Sensitivity Temperature driftTypical:0.02%FS/ Max0.05%FS/Operating Temperature 080(Customized product to 100)Compensation Temperature 0 70Storage Temperature -40100Electric Protection Reverse connect protection Excess voltage protectionProtection Grade IP68Measurement Medium water oilPressure ConnectionInput Type; Mounted Type(G1/4 G1/2 M20*1.5 selectable)Shell Stainless SteelSupply 9-36VDC (Typical24V)Output Signal 4-20mAFeature:1 Prevent from the surge voltage over-voltage over-current and the protection of reversed polarity;2 Do the test to make sure the ability of overload resistance and shock resistance previously ensure the overload capacity;3 Implement the electromagnetic interference resistance to avoid the problem taken place under the condition ofComplicated electromagnetism environment;
