The HTS-LM02X series submersible level transmitter (dedicated to wastewater and sludge) is based on the principle that the static pressure of the measured liquid is proportional to its height. The product utilizes the piezoresistive effect of a ceramic sensing element to convert static pressure into an electrical signal. This signal is then processed by dedicated digital circuitry, including signal amplification, linear compensation, interference suppression, and surge protection, before outputting an industrial-standard signal. The probe is designed with different pressure inlet methods to protect the diaphragm under various operating conditions, making it suitable for applications in wastewater and sludge.
