Introduction

LV70 series flanged static pressure liquid level transmitter is based on ceramic capacitor technology. When the liquid level increases, the pressure on the ceramic capacitor increases, which increases the capacitance value, and the capacitance value is proportional to the liquid level.

Features

Flange installation, strong overload capacity, good stability, better than 0.1% of the full scale per year, strong anti-interference ability, extremely high accuracy and repeatability, up to 0.2, 0.5 grades, can adjust the zero point and full scale on site . The ceramic measuring interface has good corrosion resistance.

application

It is used for viscous and slurry media, strong corrosive liquid, and particle-rich media, and is not easy to block.

* Since the transmitter is a hydrostatic level gauge, it is essentially a pressure transmitter. When it is installed at the bottom of the container, the measured pressure is proportional to the height of the liquid level. Here the maximum range of 0~200 meters is calculated by taking water as an example: that is, the maximum range of the transmitter is 0~20bar, 1bar corresponds to ten meters of water column, and the water measurement range is 0~200 meters. However, the selection data is still in bar. For example, the range is 0~200 meters, and "20" should be filled in the second digit of the selection table. Actual digital users can fill in according to their own requirements.
