Continuous measurement

For continuous level measurement the level is detected continuously, con-verted into an electrical signal and indicated. Depending on the type the units have freely programmable switching outputs or an analogue output for further processing.

Point level measurement

For limit detection a defined level reached is detected and converted into an electrical switching signal. Thanks to the microprocessor technology the user can adjust the sensors to the medium by pressing buttons. The integrated electronics ensure an exact repeatability of the set switch points.

Switching amplifier for Namur sensors according to 94/9/EG (ATEX)

NAMUR switching amplifiers evaluate the sensor signal and control the output. They meet all requirements of the ATEX directives. Switching amplifiers with relay and active transistor and potential-free optocoupler outputs are available. The control circuits hold the approval Ex II (1) GD [EEx ia] IIC. The amplifiers are designed for the connection to NAMUR sensors according to DIN EN 60947-5-6 and mechanical switches. They provide the supply voltage for the intrinsically safe circuit.
