Burkert's New Non-Contact Radar Sensors Allow Level Measuring in Hygienic & Aggressive Environments at up to 150C
Burkert is expanding both the range and the media types that can be measured using non -contact radar technology, with the launch of its Type 8136, 8137 and 8138 modular radar transmitters.
The addition of the new radar sensors allows level measuring in normal, aggressive and hygienic operating environments, at pressures up to 40-bar and temperatures (on hygiene transmitters) to 150C, providing the facility for CIP and SIP.
The addition of the new radar sensors to Burkert's existing ranges of ultrasonic, guided microwave and vibrating level sensors means that Burkert can now measure open channel flow & tank levels for a broad range of solids & liquids covering 95% of all level applications with dielectric values as low as 1.7.
The radar sensors offer operating benefits across a wide range of process industries, including food & beverages, - especially breweries and dairies, and also pharmaceuticals, water treatment - pure water and sewage, and pulp and paper. They are highly reliable, non contact devices that are suitable for CIP and SIP processes, and are largely impervious to atmospheric conditions such as temperature, pressure, dust, vapour and condensate.
The base unit in the new sensor range, the Type 8136, is a modular radar transmitter designed for simple process applications - typically, measuring flow in open channels or levels in open tanks - as a superior alternative to ultrasonic transmitters. The device is designed for use at pressures up to 3- bars maximum, and fluid temperatures of 80°C. It is supplied with threaded connections G/NPT 1½", and is supported by optional mounting brackets.
Developed for demanding applications, the Type 8137 operates at temperatures up to 130°C and pressures up to 40- bar. Using optimised antenna, the device can measure at distances up to 30m, even in aggressive environments. In common with the Type 8136, the 8137 is supplied as standard with G/NPT 1½", but with the added options of DIN and ANSI flange connections.
The final unit in the new range, the Type 8138, has been developed specifically for hygienic applications in food and beverage and pharmaceutical industries. The 8138 can operate at fluid temperatures up 150°C, and depending on the flange connection employed, at pressures up to 16- bar. These extreme operating parameters, plus the hygienic design of the 8138's flange connections ensure that cleaning - and steam sterlisation - of the device can be carried out to the highest possible regulatory standards. The Type 8138 is equipped with a TriClamp 2"connection as standard, with, Varivent DN25, and DN50 and DN100 DIN-Flanges also available.
All the sensors in the new range can be delivered with or without displays. They will shortly be joined by versions that are suitable for potentially explosive atmospheres, according to Ex ia IIC T6, for zones 1/2G and 2G.Certification for these devices is planned but not yet carried out.
Burkert is supporting the new radar sensors with intuitive PACTWARETM -an industry -standard software platform. This provides a configuration tool with a PC using HART communication and DTM's. The software allows simple configuration of custom tank configurations, and provides easily selectable pre- programmed open channel flow configurations, and also false echo suppression, among many other features. The software can be downloaded free-of-charge from Burkert's website, at www.burkert.co.uk.
