These radar sensors allow level measuring in normal, aggressive and hygienic operating environments, at pressures up to 40 bar and temperatures (on hygiene transmitters) to 150°C.
The addition of the radar sensors to the company's ultrasonic, guided microwave and vibrating level sensors means that Burkert can now measure open channel flow and tank levels for a range of solids and liquids covering 95% of all level applications with dielectric values as low as 1.7.
The company says the radar sensors offer operating benefits across a range of process industries, including pharmaceuticals and water treatment - pure water and sewage, and pulp and paper. They are reliable and largely impervious to atmospheric conditions such as temperature, pressure, dust, vapour and condensate.
Type 8136 is a modular radar transmitter for simple process applications - typically, measuring flow in open channels or levels in open tanks. The device is used at pressures up to 3 bar maximum and fluid temperatures of 80°C.
Type 8137, for more demanding applications, operates at up to 130°C and pressures of 40 bar. Using optimised antenna, the device can measure at distances up to 30m, even in aggressive environments.
Type 8138 is for hygienic applications in the pharmaceutical industry. It operates at fluid temperatures up to 150°C and, depending on the flange connection employed, at pressures up to 16 bar.
All of the sensors are available with or without displays. They will soon be joined by versions for potentially explosive atmospheres.
Burkert is supporting the sensors with Pactware software, which allows simple configuration and can be downloaded free-of-charge from Burkert's website.
