The ESMWLPS submersible water level sensor is a liquid level measurement instrument based on the principle of pressure sensing. The probe is directly immersed at the bottom of the liquid, and it calculates the water level depth by sensing the water pressure. The core uses a diffused silicon piezoresistive chip and outputs a 4–20mA standard analog signal, which can be directly connected to a PLC, digital display, or control cabinet.

ESMLWGY Series Turbine Flow Sensor（Hereinafter referred to as sensor）Based on the principle of torque balance，It belongs to speed flow meter. The sensor has the characteristics of simple structure, light weight, high precision, good repeatability, responsiveness, easy installation and maintenance, etc. It is widely used in petroleum, chemical, metallurgy, water supply, paper making and other industries.

Assembled K type thermocouple is the most common industrial temperature sensor for stable and cost‑effective measurement from 0℃ to 1200℃. It adopts standard K grade thermocouple wire with good linearity, reliable stability and fast thermal response. Built with insulated core, heavy‑duty protection tube and sealed connection head, it supports stainless steel and ceramic sleeves against high temperature, corrosion and oxidation.

PP Float Switch (Polypropylene Float Switch) is a liquid level control sensor with a simple structure, low cost, corrosion resistance, and durability, working based on the principle of buoyancy and reed switch. It is widely used for liquid level alarms and automatic control of corrosive liquids, clean water, wastewater, and oils.
