Product Description
HPM418 liquid level transmitter is a fully sealed submersible structure and uses an anti-corrosion, wear-resistant and high-precision ceramic capacitive pressure sensor. The probe put into the measured medium is made of 316L or titanium alloy, and the gas conductive cable is made of PTFE or polyurethane cable. It 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.

Installation
1. Threaded M ounting Parts(W1)
2. Top connection heavy hammer W2)
3. Level transmitter
4. Cable clip(W8)
5. Protective tube
6. Bottom connection heavy hammer(W3)
(1,2,4,5,6 needs to purchased separately)
Notes:If heavy hammer in bottom, need to consider the influence of the height of the bottom hammer on the height from the sensing diaphragm to the bottom of the measurement medium.
