FlexTop versions 2211, 2221 and 2231 allow the input to be configured for a resistance thermometer as well as for thermocouples, resistance sensors and current or voltage signals.
The stainless steel housing makes it extremely resistant to a a number of aggressive liquids.
Integrated electronic devices that require no special settings make the sensor easy to operate.
All parts exposed to surrounding media withstand a compression load of up to 40bar.
The optical principle allows fluids to be detected easily, in a wear-free and continuous process that does not require an electrical connection or a mechanical movement between fluid and sensor.
Depending on whether the sensor tip is surrounded by liquid or air, the limit angle for the total reflectance of the light changes.
If the sensor tip is surrounded by liquid, the light beam is diverted into the fluid and the sensor exit changes its switching status.
The liquid medium can be conductive, nonconducting, cloudy or clear.
For hazardous locations or applications with cramped space conditions, optical fibre versions are available.
A special sensor head preventing drop formation makes these versions highly chemical-resistant and suitable for temperatures of up to 105C.
