Product Description
HPM410 submersible liquid level transmitter adopts a fully sealed submersible structure. This type of transmitter is composed of a pressure sensor that has undergone long-term stability and reliability testing and a high-precision signal conditioning dedicated circuit installed in a stainless-steel shell. The integrated structure and standardized signals provide a reliable solution for on-site use and automated control. convenient. The special cable is sealed with the housing and can be used in liquids compatible with the transmitter structural material for a long time. The shell of this product adopts a fully welded process, and the connections of the shell, cables 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.
