Overview
The OPTIFLEX 1100 is a guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. It is designed for basic storage applications in non-hazardous areas. The level transmitter is a higher performing replacement for traditional level transmitters such as RF capacitance or conductive level transmitters.
Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.
- Three types of probes which can all be shortened on site
- Removal of the converter under process conditions and 360° rotation to make the display screen easier to read
- Display keypad buttons directly accessible without opening the housing cover
