Product details
Product Overview:
The YDW series is a liquid level transmitter produced using internationally advanced diffusion silicon sensing technology. Different sensing cores can be selected according to actual applications, and a stainless steel sealing structure is used. There can be multiple signal outputs, with a wide range of measurement range, good long-term stability, anti clogging, and no blockage caused by viscous media during the measurement process. The integrated structure design is suitable for pressure measurement and control of viscous media such as sewage, chemical coatings, paints, mud, asphalt, crude oil, etc. with high impurities. Suitable for various places that require precise measurement of fluid pressure, such as petrochemical, environmental monitoring, water conservancy engineering, oil tanks, and other occasions for liquid level measurement.
Product features:
Simple exterior design, high cost-effectiveness, anti clogging, good linearity
Easy to install, easy to clean, directly put into the medium for use
Waterproof ventilation cable tightly connected to the casing
All stainless steel packaging, measuring end with stainless steel isolation membrane
Small temperature drift, high precision, stable and reliable performance
Can replace similar imported products
Excellent EMC performance, compliant with CE certification
Provide OEM services and accept customer customization
Applied in the field of liquid level measurement for environmental water conservancy such as river water, sewage, and deep sludge
By using a ventilation waterproof adapter device, it can effectively prevent the influence of atmospheric pressure on accuracy and improve
