The 3300 Series Wave Radar Level Interface Transmitter comprises smart, loop-powered level and interface transmitters based on the guided wave radar technology. These instruments provide outstanding reliable measurements on liquids and slurries even for severe conditions, due to advanced signal processing with digital sampling and high signal to noise ratio.
- First loop-powered level and interface transmitter. Multivariable output from one device reduces process penetrations and installation costs.
- Direct level measurement means no compensation for changes in temperature, pressure, density, dielectric or conductivity.
- Virtually unaffected by dust, vapor, interfering obstacles and turbulence. Even suitable for small or odd shaped tanks.
- Intrinsically safe and Explosion Proof makes it suitable for hazardous areas.
- PC setup software with installation wizard provides easy configuration.
- Dual compartment transmitter housing (electronics and cabling separated) which can be removed without opening the tank, and cut-to-fit probes facilitate easy installation and minimize need for maintenance.
- Compatible with the Asset Management Solutions (AMS) plant management software - cuts costs by streamlining maintenance tasks.
APPLICATIONS |
The 3300 Series can be used for level measurements on most liquids, semi-liquids and liquid / liquid interfaces.
The 3300 Radar Level Transmitter consists of two models:
- Model 3301, Guided Wave Radar Level Transmitter for liquids and some solids
- Model 3302, Multivariable Guided Wave Radar Level and Interface Transmitter for liquids.
Rosemount 3300 Guided Wave Radar transmitters offer high reliability and performance.
Measurements are virtually unaffected by temperature, pressure, vapor gas mixtures, density, turbulence, bubbling / boiling, varying dielectric media and viscosity.
Since the waves are guided along the probe, this technology is excellent for small and narrow tanks / tank openings.
Suitable for measurements in:
- Chemical and petrochemical industry
- Oil and gas industry
- Pulp and paper industry
- Pharmaceuitcal plants
- Food and beverage industry
- Water and sewage treatment
- Hydroelectric dams and power plants

MEASUREMENT PRINCIPLE |
 |
The 3300 Series is based on the TDR (Time Domain Reflectometry) technology. Low power nano-second microwave pulses are guided down a probe immersed in the process media.
When a radar pulse reaches a media with different dielectric constant, part of the energy is reflected back to the transmitter and the time difference between the transmitted (reference) and the reflected pulse is converted into a distance from which the total level or interface level is calculated.
The intensity of the reflection depends on the dielectric constant of the product. The higher dielectric constant value, the stronger the reflection will be.
The transmitter uses Dynamic Gain Optimization which means it automatically adjusts gain to maximize signal-to-noise ration in each application. This increases measurement reliability and capability. |

INPUTS / OUTPUTS
The 3300 Series transmitter uses the same two wires for both power supply and output signal (loop-powered).
The input voltage is 11-42 VDC (11-30 VDC in IS applications, 16-42 VDC in Explosion Proof / Flame Proof applications).
Measurement data is transmitted as an analog 4-20 mA signal with a superimposed digital HART signal. The HART signal can be used in a multidrop mode.
By sending the digital HART signal to the optional HART Tri-loop, it is possible to have up to three additional 4-20 mA analog signals.
See Model 333 HART Tri-loop Product Data Sheet for additional information.
The transmitter is available with Intrinsically Safe or Explosion Proof approvals. A safety isolator such as a zener barrier must be used for intrinsic safety. |
DISPLAY |
Data can be read from the optional integral display or remote by using the 4-digit LCD display model 751 Field Signal Indicator.
 |
The integral display is easily configured from Radar Configuration Tools or the HART 275 or 375 Communicator. It displays measured values by toggling between chosen variables. |

CONFIGURATION |
Configuration can easily be done either with a HART 275 or HART 375 communicator or a PC with the user-friendly, Windows based software package for setup - Radar Configuration Tools.
To communicate with the transmitter, a HART modem is required and it is included in the delivery. The HART modem can also be ordered separately.
These radar transmitters are compatible with the AMS (Asset Management Solutions) software which also can be used for configuration.
It is possible to order a pre-configured transmitter. Contact a Wessco Pretemp Industrial Instrumentation representative for details or let us know you want one pre-configured in the online form below.
