Level limit detection at a glance

Measurement principle

VibrationThe robust Soliphant level limit switchreaches its resonance frequency by means ofa piezo-electric drive. As the probe is coveredby solids, the amplitude changes and theelectronics analyse this change. This principleis characterized by a wide range of applicationsand by a measurement, free of maintenance andcalibration.

Capacitance

Capacitance level limit switches are based onthe capacitor principle. As the solids cover anduncover the probe, the capacitance changesand the electronics switch. The compactMinicap limit switch has an integrated build-upcompensation. The capacitance product rangefor bulk solids, up to a grain size of 50 mm/2"is completed by the robust Solicap M probe, incompact or rope design and by high temperatureprobes up to 400 C/752 F.

PaddleA synchronous motor drives a shaft with a paddlevia a transmission. As the paddle is slowed down

or stopped by the solids, the limit is detected.Impacts on the paddle against the direction ofrotation are absorbed by a slip clutch.

UltrasonicsProsonic T is a compact ultrasonic instrument fornon-contact level limit detection. The Prosonic Tis particularly suited to the measurement ofsmall distances. Because of its freely adjustable

switching ranges, starting at 0.25 m/0.8 ft.

Microwave barrierThe microwave signal is sent from anFQR emitter via an integrated horn antenna.

An FDR receiver installed on the oppositeside of the pipe detects the signal and issuesa switching signal to the FTR unit as themicrowave beam is interrupted by solids.

Non-contact level limit detection, free of wearand tear is possible in silos, hoppers or cyclonesthrough windows of e.g. glass or plastic material

which can be penetrated by the microwaves.

The radiometric measuring principle is basedon the attenuation of gamma rays as theypass through matter. The Gammapilot Mcompact transmitter contains a scintillator,a photomultiplier and integration electronics.Emitted gamma rays generate light ashesin the scintillator. They are fed to thephotomultiplier where they are transformedinto electric pulses and amplied. The pulserate (number of pulses per second) is anindication of the intensity of the radiation.Depending on the calibration the pulserate is converted to a level, limit detection,density or concentration signal by theevaluating electronics. Gammapilot Mis available with an NaI crystal or plasticscintillators in different lengths tin order tofacilitate installation.

PROFIBUS PA/DP andFOUNDATION Fieldbus

PROFIBUS and FOUNDATION Fieldbusare open eldbus standards. They have beenspecially designed for process engineeringand process automation purposes.

Endress+Hauser offers PROFIBUS andFOUNDATION Fieldbus instrumentsfor level, pressure, ow, liquid analysisand temperature measurement as well asrecording devices.

Advantages: Standard is not dependent on a particular

manufacturer Communication and power supply using

two-wire technology Flexible topologies and bus structures

HART protocol, e.g. via remote inquiryIn process instrumentation, the HARTprotocol has become the standard forSMART transmitters world-wide. Together

with a Fieldgate, the HART protocoloffers remote inquiry capability, remotediagnostics and remote programming. Tothis end, the Fieldgate uses the existinginfrastructures of the Internet and softwarestandards. Every Internet-compatiblecomputer can request and representmeasured values world-wide without anyadditional software.

The Fieldgate offers transparency inproduction and supply processes andopens up new possibilities in inventorymanagement e.g. time and cost optimizedroute planning for delivery vehicles.

Visualization and device congurationThe P View visualization system is a high-performance and price-effective customersolution for process visualization. Measuredtank values such as level or temperature areclearly depicted.

FieldCare conguration and assetmanagement software is based on the openFDT 1.2 standard (Field Device Tool) andprovides easy access to eld instrumentsfrom a central station irrespective of themanufacturer. FieldCare comprehensivelysupports engineering, conguration or setupand diagnosis of intelligent instruments.FieldCare makes an engineers life easier,e.g. from quick access to device manualsthrough to plant wide status monitoring ofall eld instruments.

RN221N active galvanic barrierThe RN221N provides galvanic isolation of 420 mAsignal cables. It is used for the intrinsically safeoperation of two-wire transmitters and to eliminateearthing problems.

RMA422 process transmitterThe RMA422 receives and processes measurementsignals. Its modular concept makes it the perfect processmeasurement transmitter e.g. as temperature transmitter,contactor or signal converter. Using the two input process

values, other values can be calculated.

RIA452 process displayThe digital RIA452, with 7-digitbright multi-coloured LC display

and pump control functions,receives measurement signalsfrom most eld devices and canbe installed in control rooms orin panels throughout the plant.

RIA141 eld displayThe RIA141 digital display inpressure sealed metal enclosure

(explosionproof to EEx-d) isdesigned for installation in to a420 mA power circuit and tomake your process more visibleand plant much safer.
