HDL602 high temperature liquid level transmitter consists of stainless steel gas collector, stainless steel
capillary and junction box. The sensor and signal processing circuit are designed in the junction box, and
the gas collecting cylinder is put into the measured liquid, which is responsible for collecting pressure
signals. The gas in the gas collector transmits the collected liquid level pressure signal to the sensor
through stainless steel capillary, thus avoiding the direct contact between the sensor and the measured
medium, adapting to high temperature corrosion and other occasions, effectively solving the problem
of high temperature corrosive liquid and sewage level measurement.
HDL602 series are widely used in liquid level measurement and control in environmental protection,
water conservancy, frequency conversion water supply, industrial process control, chemical industry
and other fields. When measuring medium such as sewage and silt, filter structure can be added
according to customer's requirements
