产品介绍

Description

概述

Overview

181系列液位变送器是对压力变送器技术的延伸和发展。根据不同比重的液体在不同高度所产生压力成线性关系的原理,实现对水、油及糊状物的体积、液高、重量的准确测量和传送。广泛应用于电力、石油、化工、冶金、水利、自来水、食品等行业。
Series 181 level transmitters are an extension and development of pressure transmitter technology. According to the principle that the pressure generated by different specific gravity of the liquid at different heights is in a linear relationship, accurate measurement and transmission of the volume, liquid height and weight of the water, oil and paste are possible, which is widely used in electric power, petroleum, chemical, metallurgy, water conservancy, tap water, food and other industries.

 

特点

Features

★安装简单、使用方便,互换能力强。

It is easy to install, easy to use, and has strong interchangeability.
★高品质传感器的灵敏度高,响应速度快,准确反映流动或静态液面的细微变化,测量准确度高。

The high-quality sensor has high sensitivity, fast response, accurately reflects the subtle changes of the flowing or static liquid level, and has high measurement accuracy.
★具备本安防爆和隔离防爆能力,可应用于各种危险场所。

With intrinsically safe explosion and isolation explosion-proof capabilities, it can be applied to a variety of hazardous locations.
★备有防阻塞型设计,可实现对糊状介质液位的测量。

With anti-blocking design, it can measure the level of paste medium.
100%等分刻度、LEDLCD三种指示表头,现场读十分方便。

100% divided scale, LED, LCD three indicator heads, on-site reading is very convenient.
420mA DC二线制信号传送,抗干扰能力强,传输距离远。

4 ~ 20mA DC two-wire signal transmission, strong anti-interference ability, it has long transmission distance.
★精细独特的零点、满程、非线性补偿,保证仪表使用条件范围内的精度,长期稳定性好。

Fine and unique zero, full range, non-linear compensation to ensure the accuracy of the instrument within the scope of use conditions, good long-term stability.
★压力传感器直接感测被测液位压力,不受介质起泡、沉积的影响。

The pressure sensor directly senses the measured liquid level pressure, which is not affected by the bubbling and deposition of the medium.
★使用被测介质广泛,可测油、水及与316不锈钢兼容的糊状物,具有一定的防腐能力。

Wide range of measured media, oil, water, and paste compatible with 316 stainless steels, it has a certain degree of corrosion resistance
