Features High Precision: through zero point and full scale laser calibration, the measurement of the liquid level sensor is more accurate, and the measurement range is also very wide. Temperature Compensation: This capacitive water detector accessory has internal active temperature compensation and low temperature drift to ensure higher accuracy and sensitivity. Package Content: The package includes 10 capacitive water detectors in sufficient quantity to meet your needs for replacing old parts. Good Reliability: the allowable overpressure of this ceramic base water sensor is 2.5 times of the rated range, which makes the work more safe and reliable, and you can use it with confidence. Advanced Materials: this water level sensor is designed with a ceramic base, which has high elastic modulus, is very durable, corrosion resistant, wear-resistant, and has a long service life. Specification: Item Type: Liquid Level Sensor  Model: CJ-18 Working Voltage: 2-20v Sensitivity: 2-4mv/v Operating Temperature range: -40℃-125℃ Response Time: <1ms Safe Overload and Allowable Over Pressure: 2.5 times the rated range.  Service Life: More Than 2 million range pressure cycles.  Package List: 10 x Liquid Level Sensor  Note: In addition to device drift, changes caused by temperature are also affected by factors such as installation stress relief. It is recommended to perform stress relief and other processes first. Package List 10 x Liquid Level Sensor
