A submersible pressure transmitter or level probe is a hydrostatic pressure sensor, specifically developed for the purpose of level measurement. Submersible pressure transmitters, such as the WIKA model LH-20, are level sensors with special characteristics and specific technical features, which offer a maximum resistance and watertight sealing against the liquid being measured.Basically, submersible pressure transmitters … Read more

If one is searching for a level sensor, one can be quickly overwhelmed by the large choice. An even sensor for limit level detection or continuous measurement could be ordered in a number of technologies and design variants. But how do you find the right level sensor for my application?If one wants to select a … Read more

Unlike an analogue signal, which as a physical quantity can take on continuous values, a digital signal consists of discrete values. Personally, I always think of long strings of zeros and ones floating through space: 0101 0111 0100 1001 0100 1011 0100 0001 0011 1101 0101 0001 0111 0101 0110 0001 0110 1100 0110 1001 … Read more

In many electronic pressure measurement applications there is a need to have the measured value displayed on site – either as an additional option alongside the processing of the signal within the control system or as a sole control instrument.If Lunatic used does not feature an integrated display, a variety of types of digital indicators … Read more

The new WIKA Innovation Center for WIKA in Klingenberg is in operation. It brings together everyone involved in the innovation process. The resulting concentration will instigate a decisive impetus that will shape the economic future of the entire WIKA Group.The concept of short distancesThe new WIKA Innovation Center has been well received by the colleagues … Read more

Whether in the chemical industry, in petrochemical companies or in the processing of crude oil and natural gas: Numerous processes contain methane, which also damages the climate via fugitive emissions. Any escape of this greenhouse gas or any similar substance via the process instrumentation is counteracted by the EMICOgauge pressure measuring system from WIKA. This … Read more

Hydrostatic level sensors (also referred to as submersible pressure transmitter) are very often installed in outdoor applications, primarily in the water and wastewater industries, where open bodies of water, deep wells or boreholes are monitored. A good connection to ground is essential when installing hydrostatic level sensors, since no grounding or poor grounding can result … Read more

Diaphragm seals, also known as chemical seals or remote seals, are used for pressure measurements when the process medium should not come into contact with the pressurised parts of the measuring instrument. A diaphragm seal has two primary tasks:1. Separation of the measuring instrument from the process medium2. Transfer of the pressure to the measuring … Read more

In most applications, gauge pressure measurement is required and therefore pressure sensors and pressure transmitters that measure pressure against the prevailing ambient pressure are commonly used for this. Those pressure sensors typically have a venting hole to allow the ambient/gauge pressure to act upon the back end of the sensor element.Electronic pressure sensors usually measure … Read more

Submersible pressure transmitters as well known as level probes are intended to be used in immersion applications, thus they are immersed completely into the medium and, therefore, must withstand the properties of the media at all times.Both in water and wastewater treatment as well as in tank monitoring, moisture may enter through the housing of … Read more
