IP68 Liquid Level Switch / 4-20mA Output Integrated Liquid Level Sensor
4-20mA Temperature And Pressure Integrated Liquid Level Transmitter
Introduction
KCF100 series temperature and pressure integrated liquid level transmitter is an adjustable capacitance type liquid level transmitter developed by our company for high precision and high stability measurement of oil level and water level. It has short-circuit protection and certain over-voltage surge protection capability, and has the characteristics of fast response, wide voltage supply, strong load capacity and wide temperature measurement range. It supports two calibratable analog outputs, ModBus RTU communication protocol and fast forced zero function, the overall performance is stable and reliable.
