New Burkert Type 8136, 8137 and 8138 modular radar transmitters expand both the range and the media types that can be measured using non-contact radar technology. The addition of the new radar sensors enables levels to be measured in normal, aggressive and hygienic operating environments, at pressures up to 40bar and temperatures (on hygiene transmitters) to 150 degrees C, thereby providing the facility for clean-in-place and sterilise-in-place (CIP and SIP) operations.
Burkert says that the addition of radar sensors to its existing ranges of ultrasonic, guided microwave and vibrating level sensors means that it now offers sensors for measuring open channel flow and tank levels with a broad range of solids and liquids covering 95 per cent 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 and beverages, pharmaceuticals, water treatment, 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.
At the bottom of the 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 3bar maximum and fluid temperatures of 80 degrees C. It is supplied with G/NPT 1-1/2inch threaded connections and is supported by optional mounting brackets.
Developed for demanding applications, the Type 8137 operates at temperatures up to 130 degrees C and pressures up to 40bar. 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 1-1/2inch connections but with the 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 degrees C, and depending on the flange connection employed, at pressures up to 16bar. These extreme operating parameters, plus the hygienic design of the 8138's flange connections, ensure that cleaning and steam sterilisation can be carried out to the highest possible regulatory standards. The Type 8138 is equipped with a Triclamp 2inch 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 not yet complete.
Burkert is supporting the new radar sensors with Pactware software. This provides a configuration tool with a PC using Hart communication and DTMs. 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 freely downloaded from Burkert's website.
