Pressure transmitter

handling and use

Electrical pressure transmitters enable you to measure pressure in a short time with relatively little effort. The transmitter can check different types of pressure here. Absolute pressure, along with relative pressure and differential pressure can all be measured. The product itself is a great help if you want to measure the density, flow rate or fill level. These values are of particular importance, especially in the industrial sector. This is the only way you can ensure you are able to work effectively with the measured values.

buy transmitters for pressure measurement

If you want to buy a pressure transmitter, there are some points which you need to keep in mind:

  • type of measurement

  • high precision through low measuring range

  • if necessary, alarm management

  • reconciliation and analyses can be carried out

Overview of pressure transmitter

Pressure transducers – measuring different types of pressure

The pressure transmitter is capable of measuring different types of pressure. What these types are, depends on the instrument in this case.

The features of a good pressure transducer

As a rule, pressure transducers have specific features. In most cases, they have a measuring range of 4-20 mA and are operated with 0-10 V. The measuring range is of primary interest. Accuracy is higher with a lower measuring range. If you need very differentiated values, this should then be an important aspect when it comes to making your selection.

Modern pressure transmitters are now capable of monitoring drying processes effectively. For this, they are often equipped with an alarm range which you can use. Depending on the settings, you receive a signal when the pressure falls or rises to a dangerous range. This enables fast responses. In summary, that means:

  • measuring range plays a major role

  • alarm signal may make sense

  • type of pressure measured is also important

Effective comparison of pressure transducers

Testo has a variety of pressure transmitters on offer. Here you have the opportunity to make a comparison. The high-quality instruments come in different designs. The elements you can compare include measuring ranges, along with stability and accuracy. Different features are important, depending on the areas where you intend to use the pressure transmitter. For example, if you need a model for cleanrooms, it must have the flattest possible housing, so that it can be easily integrated into the wall. A model with a display is again helpful for a better readout of the results. If you rely on being able to respond quickly in the relevant areas, an alarm is also a sensible feature.

Transducers – fields of application of a pressure transducer

Testo's pressure transmitters are a great help when it comes to checking pressure ranges. You can supplement these results by using a temperature transducer or a humidity transducer. Some instruments are even capable of checking temperature and humidity as well. Here, the fields of application include the monitoring of volume flows or also the monitoring of important drying processes. They are indispensable in the field of air conditioning technology in particular.

Transducer with flow calculation

Testo offers you the option of ordering a transmitter with flow calculation. These instruments have the advantage of being able to measure the flow velocity and volume flow as well as the pressure. The measuring ranges are kept very low from 10 Pa. This means you benefit from high precision. In some cases, you also get the temperature and humidity checking feature.

The advantages of a transducer with flow calculation are:

  • additional calculation of the flows

  • humidity and temperature can be measured in some cases

  • very easy to handle

  • precise results in a short time
