XQ sender how to buy?

After several years of continuous improvement and upgrading, the XQ transmitter has greatly improved its performance indicators, and its varieties and specifications are all complete. The output of the switch is no longer relying on the reed switch but uses a high-power micro switch. Due to the different ambient temperatures on the site, the XQ transmitters are classified according to ambient temperature, with room-temperature, medium-temperature, and high-temperature types. In the case of normal temperature and medium temperature type, the two have a tendency to merge from the current order and use. Due to the different environmental explosion-proof requirements in use, XQ transmitters are available in normal, intrinsically safe and flameproof versions. All parts and components of the XQ sender are upgraded through mold processing or the purchase of standard parts, so the sensitivity and consistency of the whole machine have been improved. The quality of the product is guaranteed, especially in the maintenance, replacement of quality assurance. The auxiliary magnetic steel used in the XQ transmitter is molded by a mold and is magnetized once. The auxiliary magnetic steel rotates under the interaction of the float magnetic steel and drives the lever action. Now the shaft is changed to a miniature bearing, which makes the rotation more flexible and reliable, and the sensitivity is greatly improved.

In the technical parameters we introduce the two concepts of attraction range and minimum sensitivity, and the scope of attraction and the smallest

Sensitivity is defined as follows:

The unit of attraction range is mm. It means that the transmitter can work normally and reliably within the distance from the surface of the magnetic float. This distance range is called the range of attraction. The minimum sensitivity unit is mm, which means that the sender can still work normally and reliably at the minimum distance from the magnetic float surface. This minimum distance is called minimum sensitivity.

The introduction of these two concepts will ensure the interchangeability of XQ transmitters in all magnetic flap level gauges. Ordinary side-mounted magnetic flap liquid level gauge, vacuum anti-frost type, jacket insulation type, electric heat tracing type, high pressure type, lining PTFE type, jacket anti-hot type, etc. can be exactly interchangeable. The upgraded XQ sender and explosion-proof XQ/B sender have been greatly improved in terms of structural form and technical indicators, making the application more extensive. After several years of actual field application, it has won the trust of users and middlemen.
