Wireless Communication Interface

 


The WirelessEZ Communication Interface (radio modem) is compatible with the the SiloPatrol® SE (SMU) "smart" cable-based sensor or Flexar guided wave radar level sensor. It can also be used for wire-replacement applications for equipment not manufactured by Monitor Technologies (consult factory for details). Communication between the sensors and an operator interface like the HMI2 control console or the SiloTrack inventory management software is accomplished via half-duplex (2-wire) RS-485 communication format. The WirelessEZ Communication Interface can be used to replace the RS-485 wiring between the sensors, the HMI2 or the PC. The WirelessEZ Communication Interface can be used to lower the cost of some installations and to overcome obstacles that make hardwiring impractical or impossible.

The WirelessEZ Communication Interface uses proven frequency-hopping spread-spectrum technology, operating in the 900MHz band, to communicate between two points. The 900MHz band is a FCC license-free band and offers greater transmission distances, better signal transmission through obstructions and lower signal loss than other available higher frequency bands.

The WirelessEZ Communication Interface has a durable powder-coated die cast aluminum housing and is provided with a mounting bracket that can be used for affixing to a flat surface or pipe / railing. Each transceiver includes RS-485 half-duplex (2-wire) interface.

With reliable and affordable technology, the WirelessEZ Communication Interface can be used to lower the cost of installation and to overcome obstacles that make hardwiring impractical or impossible.

Principle of Operation

OPTIMIZED RELIABILITY
The WirelessEZ Communication Interface uses proven frequency-hopping spread spectrum technology, operating in the 900MHz band, to communicate between your PC running SiloTrack Server software or HMI2 control console and individual or groups of
SiloPatrol® SE (SMU) "smart" sensors or Flexar guided wave radar sensors. The 900MHz band is a FCC license-free band and offers greater transmission distances, better signal transmission through obstructions and lower signal loss than other possible frequency bands.

Frequency-hopping spread-spectrum radio technology utilizes a band of frequencies between 900-928MHz and continuously "hops" or switches frequencies during radio transmission enhancing reliability and minimizing disruption of the telecommunications. The spread-spectrum enables a signal to be transmitted across a frequency band that is much wider than the minimum bandwidth required by the information signal. This reduces interference and allows for increased data communication.

FLEXIBILITY
The WirelessEZ Communication Interface can be utilized in numerous applications, even with multiple sensor networks and over 100 sensors. Each sensor network will require a wireless modem/transceiver at the PC. A wireless modem/transceiver is also required at the sensor(s) location. SMU and Flexar sensors need to reside on separate RS-485 networks.

 



Single Network/Point-to-Point: One transceiver is located at the PC and one at a group of sensors or at a single sensor. If used with a grouping of sensors located in close proximity, the sensors would be wired together with the transceiver.

Single Network/Multiple-Point: One transceiver is located at the PC and one transceiver at each of multiple groups of sensors within a single network or one transceiver at each sensor.



Multiple Networks/Point-to-Point: One transceiver for each network of sensors at the PC and one transceiver at each network group of sensors.



Multiple Networks/Multiple-Point: One transceiver is located at the PC for each network and one transceiver at each of multiple groups of sensors within each network or one transceiver at each sensor within each network.

 

 

 
Model Selection

The WirelessEZ Communication Interface has a powder coated die cast aluminum housing that is suitable for indoor or outdoor mounting and is provided with a mounting bracket that be used for mounting on a flat surface or pipe/railing.

Radio channels & communication / serial ports are pre-programmed at the factory based on your rquirements:
> Select communication protocol: SMU, Flexar or customer-
specified
>
Select radio channel #: 1-10, Channel #1 is standard

QuantiMassTM
Mass Flow Measurement Systems
The QuantiMass in-line mass flow sensor measures the flow of quantities in pneumatic conveying & free-falling processes. The sensor is based on the latest Microwave Doppler Effect technology and provides fast, in-line / on-line measuring without the use of weight scales.
The sturdy, non-intrusive design of the sensor minimizes maintenance. In addition, the compact size of the sensor makes for easy installation into existing processes. Suitable for powders, dust, pellets, and granular up to 0.75 inch (2cm).

Versions:
Ultra Series-Includes controller
PRO Series-Includes transmitter

A practical application for the QuantiMass would be to monitor material flow rates to verify blending mixture ratios.

Principle of Operation:
The QuantiMass Mass Flow Measurement Sensor / Meter is designed with the latest microwave technology and is used to continuously quantify the flow of powders & solids being conveyed in metallic pipes. The QuantiMass is based on technology that has been developed and proven by Muetec Intruments over several years. The measurement process of the sensor is centered on the Doppler effect. The mass flow-rate is determined by evaluating the frequency and amplitude changes during the measurement process. Particles at rest, such as deposits, do not influence the measurement. All powders, dust, pellets and granules can be measured reproducibly, up to the size of 0.75 inch (2cm). The QuantiMass sensor is suitable for continuous in-line / on-line measurements in pneumatic conveying or in free-fall pipelines.
