Coat-Endure is a microcontroller based compact coat-immune admittance level limit switch. It is suitable for sticky solids and pastes. The device has been designed for compact silos and packaging machines where material has tendency to stick on the probe.
Coat-Endure is an improvement over traditional principle of admittance. The 3-element 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 the 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.

Working of Coat Endure
Coat-Endure 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-Endudre in avoiding material build-up/coating in small probe lengths.
Industries such as packaging units often require packing batches of varied media(different dielectric constants). Standard Admittance level switches require re-calibration each time process material is changed.
Coat-Endure’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 manufacturing processes are dynamic; even with modern temperature control equipment, maintaining constant process conditions is not practically possible round the clock.
Coat-Endure successfully compensates the effect of varying temperature and material build-up with its microprocessor based switching algorithm.
A first in the industry.
A concoction of chemicals, sticky slurries and dairy products such as yoghurt, honey, soya lecithin, tomato ketchup etc. are often viscous, sticky and more over conductive. As a first in the industry, Coat-Endure has been a successful level sensor for these applications.

Packaging plant manufacturers or OEMs(Original Equipment Manufacturers) desire outputs suitable at the end-user’s site. Relay and PNP (Open Collector PNP) outputs though standard are generally available only in separate models.
In a close understanding of our customer behaviour we have launched a single model with both Relay and PNP output with an input power supply from 24 V DC – 265 V AC on the same two terminals. This directly results in savings by reducing the required inventory.
up to 150°C
Suitable for a wide range of media (conductive slurries, non-conductive materials, low dielectric media)
up to 150°C
High temperature applications – 250°C to 1000°C
