Introduction

Principle & Structure 

Temperature principle: The thermal resistance signal of PT100 or PT1000 transmits the current signal through transportation and displays the current temperature value of the measured medium locally.

Pressure principle: Based on the principle of diffusion silicon, all stainless steel shell, waterproof design, used for liquid level measurement.

application
