Coat-Endure-T is an innovation resulting from the success of Coat-Endure and an unmet need of a compact coating immune admittance based level switch. Whereas compact vibrating forks for liquids have proven to be very successful for space constrained silos; slurries and pastes tend to be sticky, where vibrating forks could malfunction due to a coating of application material.
The instrument when calibrated at a single point i.e. in air, can be used with a variety of materials for level detection. When material reaches the switching point, the instrument detects the presence of the material and changes the outputs accordingly. The relay contacts / PNP output / current output can be used for maintaining the level of the material within the desired range in the tank.
Coat-Endure is an improvement over traditional principle of admittance. The ring type probe has alternating active and inactive regions,which help the controller to calculate the extent of coating on probe. In effect the device is able to identify the relative coating between sense and the shield by measuring their individual capacitances. As the coating immunity is controlled by the on board microcontroller, the extent of coating immunity can be set easily.

Input power supply & Outputs
Depends on the application media. e.g. for dry sand response times are:
Performed with the help of a magnetic key
Coat-Endure-T values your real estate, it performs its best even in short probe lengths of 65mm.
Traditional admittance level sensors are not as effective as Coat-Endure-T in avoiding material build-up / coating with short probe lengths.
Quick-on valve type DIN connector serves as a direct substitute to liquid vibrating forks in applications for solids.
Industries such as packaging units often require packing batches of varied media(different dielectric constants). Standard Admittance level switches require re-calibration each time the process material is changed.
Coat-Endure-T’s calibration is Application Material Independent; once calibrated in an empty tank it can work with a wide range of non-conductive media.
We understand that manufacturing processes are dynamic; even with modern temperature control equipment, maintaining constant process conditions is not practically possible round the clock.
Coat-Endure-T successfully compensates the effect of varying temperature and material build-up with its microprocessor based switching algorithm.
A concoction of chemicals, sticky slurries and dairy products such as yogurt, honey, soya lecithin, tomato ketchup (see full list here) are often viscous, sticky and more over, conductive. As a first in the industry, Coat-Endure-T has been a successful level sensor for these applications.
Calibration and settings can be achieved through a single magnetic key and multicoloured LED indications.
