HPM413 liquid level transmitter is a fully sealed submersible structure and uses an anti-corrosion ceramic piezoresistive pressure sensor. The probe put into the measured medium is made of 316L or titanium alloy. Cables are made of PTFE or polyurethane cables.
This product is mainly used in sewage, seawater and other media and all high-demand liquid level measurements. The shell of this product adopts a full welding process, and the connections of the shell, wires and other links are reliably sealed with multiple designs. The interior adopts a full potting process to ensure that the product has a long service life and is widely used in the chemical industry, water treatment, environmental protection, medicine, industrial process control and many other occasions
