Smartsaa Instruments (I) Private Limited

SMARTsaa offers Signal Isolator, converters and transmitters for use in process control industries. Varieties of models are available for specific applications. These converters are extensively used in cement, fertilizer, chemical and processing plants.

In process plant many signals are generated at field. These signals are generated at field sensors like position transmitter, temperature sensor, voltage, power transmitter.

These signals are not isolated from input and not suitable for transmission over long distance. Converters are specially developed to overcome these problems in transmission such as line drop, interference, ground looping, and non compatibility to standard processing unit.

Temperature Transmitters receives signal from field temperature sensor like (Pt 100, thermocouple) & convert these in suitable form like 4-20mA. These are generally head mounted type and housed in the compact terminal compartment of temp sensor..

 

Signal Isolator         : I/P 4-20 mA, O/P: 4-20 mA

Signal Convertor     : I/P from field transducer. O/P: as per requirement

Signal Repeater      : I/P : One   O/P : Multiples

Head Mounted Temp Transmitters: I/P: RTD or thermocouple: O/P 4-20 mA

 

Salient features:

1) Complete galvanic isolation between input output and control supply.

2) Independent zero and span adjustments

3) Stable current output eliminates need for special cable, shielding.

4) Robust cast Al.enclosure suitable for field mounting.

SMARTsaa offers Microwave Type Chute Block Switches for different applications and use. These switches are used to detect block chute condition.

Chute Block Switch is basically used for sensing the chute blockage in the hopper / Discharge Chute. It senses jammed condition of the hopper / Chute due to clogging at the discharge points.

Switch is used for sensing chute jamming of iron ore, cement, lime, food stuff, milk powder, and flour, salt & plastic granules. By using these switches, the feeding mechanism like conveyor, motor, pump can be stopped.

Please provide following information for proper selection of Chute Block Switch

1.     Hopper Drawing and location of switch

2.     Material to be sensed

3.     Material property like Particle size ( Min and Max ) in mm

4.     Bulk Density

5.     Max Temperature of material

6.      Moisture contain in the material

7.     Area of application ( if Hazardous )

8.     Supply Voltage

9.     O/P Contacts

Omnicomm offers FUELSCAN® is a unique in-house fuel analysis technology that enables OMNICOMM fuel-level sensors to deliver unprecedented accuracy of99.5% in all conditions.

Factors such as oil manufacturing methods and additives used in gasoline productioncause differences in the physical characteristics of fuel, which becomes an issue whenfuelling at different stations or switching from winter to summer fuel. Capacitivesensors use a specific characteristic (permittivity) to calculate fuel levels that candiffer significantly from the permittivity of the fuel used during calibration – causingerrors in fuel-level calculations of up to 30%.

FUELSCAN® compares the physical characteristics of filled fuel with the characteris-tics of the fuel used for calibration to introduce a correction coefficient that automati-cally adjusts sensor readings to deliver accurate measurements

SMARTsaa developed Capacitance type continuous level transmitter for measuring levels of conducting and non conducting liquids.

APPLICATION:

Level measurement of liquids in tank and vessels with analogue O/P

Level transmitter for conducting liquids like water, feed water, fruit juice, milk, wine acids and  non conducting liquid like oils , diesel and hydrocarbons like Acetone, Ammonia and Benzene

OPERATING PRINCIPLE:

The probe forms an electrical capacitor with the surrounding metal contained wall, or with auxiliary reference probe. With the vessel empty, initial capacitances exists between the electrode and the metal well or the auxiliary reference probe. When the probe become covered with material to be measured the capacitances will increase and the change will be measured and covered into an analogue (4-20 mA) output signal proportional to the change. Rod or flexible cable can be used for various conductive or non conductive Liquids

FEATURES:

·       Compact, Low cost

·       Analogue 4-20 mA, loop powered / 0-5 V O/P

·       Rugged probe design

SPECIFICATIONS:

Supply               :  24 V DC,

O/P                    :  4-20 mA, loop powered, 0-5 V DC, 0-10 V DC, 3 wire type

Measuring Range for liquid: Rod Probe: 0.2 to 3 Mtrs, Rope Probe: 1 to 20 Mtrs

Probe material  :  SS / Part or full insulation (for conducting liquids) by PTFE as per requirement

Conductive material: Water based solutions. Acids, Bases etc – only insulated probe

 

Non Conducting materials: Like petrochemical and solvents – Insulated or non insulated probe

Mounting           :  Vertical, ½ inch process connection or flanged

DETAILS REQUIRED:

Liquid to be sensed, Density, Conducting / Non conducting, Probe Length, Insulation, Operating length, Operating Temp, Operating Pressure, Tank material, process connection, O/P
