Sensors for the chemical industry

State-of-the-art sensors for chemical plants ensure accurate measurements, increase operational efficiency and lower long-term maintenance costs

Outdated technology can compromise both production processes and availability. Older measuring technologies leveraging mechanical components are less accurate and require higher levels of maintenance than modern equivalents in order to ensure production. Investing today to replace old mechanical devices with innovative sensor technology will pay dividends in the long run, both in productivity gains and maintenance cost savings.

应用

Measure polymerization viscosity efficiently

Viscosity is a crucial fluid property and a fundamental measurement parameter in polymerization process control. As a variable, it can be used to monitor product quality. Older viscosity measuring devices using mechanical components require regular maintenance to ensure filters are kept clear and production is running.

Polymerization viscosity measurement with Promass I
我们的行业专业知识

The Endress+Hauser Coriolis Promass I flowmeter offers multiple benefits over older mechanical devices for peak performance at reduced operational costs.

  • No filter required, meaning significant time and cost savings in maintenance with sustained process performance and safety

  • Optimize product quality with a single measuring point. In-line multivariable measurement of flow, density, temperature and viscosity

  • Minimize pressure loss with a straight, single-tube design

Prolong sensor lifetimes

In Olefin, quenching pH measurement of the contaminated quench water at regular intervals can go a long way to helping prevent fouling in the bottom of the tower. Cleaning sensors at least every other day is required, a time-consuming and labor-intensive activity which, if left undone, can result in their needing to be replaced every two weeks.

我们的行业专业知识

The Endress+Hauser Liquiline CDC90 extends the lifetime of your sensor more than thirtyfold.

  • Save time with in-process cleaning and calibration with no electrode removal necessary

  • Spur efficiency with self-diagnostic systems such as sensor conditioning checks

  • Foster safety for people and processes as no handling of contaminated water is needed

Prevent unplanned shutdowns

Use of old, magnetic level gauge devices during olefin fractionation in high-temperature environments can reduce safety and result in unreliable measurements. Moreover, unplanned shutdowns can occur if the temperature gets too high.

The Endress+Hauser Levelflex FMP51 guided wave radar ensures controlled, reliable fractionation.

  • Measure levels remotely, continuously and reliably in high-temperature conditions based on the time-of-flight principle

  • Avoid unplanned shutdowns by detecting false trips which create the risk of a stuck device

  • Enhance safety with a second unit connected to the Safety Instrumented System (SIS)
