Gas Alarm Systems ) in association with Gas Alarm Systems Australia offer Pump monitoring with differential pressure transmitter and switch: DE39

 

Pumps of all sizes are used throughout the process industries to transfer a wide range of fluids. Often the pump system within each process runs at a high cost. Hence pump monitoring is very crucial as it can protect the pump from serious damage and prevent even greater operation losses.

 

The pump’s performance can be measured by differential pressure between the suction and discharge nozzle. The differential pressure would indicate how well a pump is performing as well as it would point out the areas to improve its performance. Reducing the pressure loss within each process reduces the need for larger expensive pump and would help creating a better end product.

 

Our differential transmitter DE39 in its version with a LC display offers the possibility of displaying the inlet pressure P-, the outlet pressure P+, the differential pressure dP, and the volume flow. The volume flow can be calculated by the unit and the can be assigned to the analog output signal. This output signal in turn can control the pump by regulating the flow with the speed adjustments. The second output signal is proportional to the pressure and can be assigned to either suction or discharge pressure. Both potential free switch contacts can be freely assigned to either channel. Irregular operating conditions can be read on the display or can be assessed by two analog output signals and appropriate corrective actions can be taken.

 

Thus monitoring the performance of the pump improves it’s efficiency, helps to run the pump with very little maintenance for decades and reduces overall operation cost.

Operating Current24vdc
Power Supplier230vDc

A fire engine or a fire truck is primarily used for firefighting operations. Prior to entering the fire affected area, the fire truck should always be prepared with sufficient water level, pump engine fuel and vehicle fuel. Hence monitoring and keeping a track of water as well as fuel level is of utmost importance.

 

Alvi Technologies presents Tank level sensor NC56 along with digital level indicator EA14 that determines and indicates how much fuel or water is left in the tank; keeping the fire truck water and fuel ready for any emergency situation. The NC56 capacitive tank level sensor is installed vertically downward at the top of the vessel in which liquid level is to be measured. The sensor gives out a linear 4….20mA signal directly proportional to the level. Once the level is known, communicating and conveying the level information is the next critical step. This can be achieved by connecting tank level sensor to EA14 monitor. The EA14 converts and displays it into a volume (litres).

 

Some places require monitoring of many vehicles at the same time. For such applications we can provide an indicator that can take up to four the tank level sensors simultaneously. Please e-mail us for further information.

 

In addition to monitoring the liquid level in fire trucks, these tank level sensors can be adapted to various other applications. Please contact us for further information.

Instruments for measurement of variables such as pressure, temperature, level, and flow in the process allows the system operators to monitor the condition and movement of liquids and gases. Differential pressure transmitter is widely used in filter monitoring. Our Differential pressure transmitter DE13 can greatly reduce operator error, improve process efficiency and reduce maintenance.

 

A filter removes unwanted particles or contaminants from a gas or liquid system. When a filter becomes clogged, efficiency and pressure drops. A filter should be removed or repaired only when it is in an unhealthy state. If it is removed before that, it leads to loss of time, manpower and money. On the other hand if it is left for too long, the process efficiency is compromised. The only way to get an indication of an unhealthy filter is via continuously monitoring the condition of filter.

 

Many processes use two pressure transmitters to identify the change in process pressure conditions which in turn reflects the filter status. However, we strongly suggest to use one instrument instead, for a better accuracy.

Our differential pressure transmitter DE13 directly measures the differential pressure, provides a digital display and a standard analog output. The analog output signal can be used to indicate if the filter is clogged or is about to be clogged. Differential pressure transmitter DE13 comes with a rugged, wear resistant sensor design with a very low low hysteresis.

ALVI Automation – India offers Custom Built FISCHER/Germany Differential Pressure Switch model no DS1302VAYYYD0064

Principles of Operation :
This differential pressure instrument is based on a rugged and uncomplicated diaphragm movement, suitable for overpressure, partial vacuum and differential pressure measurements. The system’s operating principle is identical for all applications of this type. In a state of balance, forces of springs on both sides of diaphragm are balanced. The Pressure or differential pressure to be measured creates an unbalanced force of springs for measuring range until a new balance is reached. When subjected to excessive pressure, the diaphragm rests on metal supporting plates. A centre-mounted tappet transfers motion of the diaphragm system to indicator movement and to initiating elements of the microswitches.

General Specifications :
  • Max. static operating pressure : acc. to measuring range (see ordering code)
  • Max. pressure load : one-sided overpressure protected up to nominal pressure on (+) – and (-) side of diaphragm, partial vacuum protected
  • Perm. medium temperature : 70°C
  • Protection class : IP 54 acc. to DIN EN 60529

ALVI India in association with ALVI Australia takes pride to offer Fischer – NB10 Well probe for liquid level detection.

 

Application :

Measuring probes for hydrostatic measurement of fluid fill-levels. Some examples of typical applications are water or fluid fill-level measurements in

  • Wells
  • Drill holes
  • Wastewater systems and
  • Containers

Most Important Features

  • High measuring accuracy
  • Low hystersis
  • Corrosion-resistant materials
  • Integrated measurement converter
  • Measured values stable over time


Design and Principle of Operation
This measuring probe is designed around a highly sensitive pressure sensor with a silicon membrane-measuring element.

A DMS resistance bridge is attached to the rear of this membrane using a thin-film method. The well probe is equipped with an indirect hydraulic pressure sensor in order to guarantee the system-inherent dead space latitude. The pressure sensor is isolated by an elastic membrane from the medium to be measured. The volume between the membrane and the pressure sensor is filled completely with a transfer fluid. When pressure is applied this silicon membrane deforms in the elastic region, altering the resistance of the resistance bridge in a response linear to the measuring pressure. These changes in resistance are converted by electronics built into the device into standardized electrical signals.

ALVI – India in association with ALVI – Australia takes pride to offer Display and switching device for Differential pressure of gaseous and fluid media.

Typical applications :
  • Differential pressure measurements in heavily soiled media
  • Filter monitoring simple pump control systems
  • Pump, compressor monitoring

Design and mode of operation :
The device is based on an electronic evaluation circuit that analyses the measuring signals P+ and P- of two integrated ceramic pressure transmitters. The signals are digitalised and sent to the analysis unit for further processing. Both signals can be shown separately.

The main feature is the calculation of the differential pressure. The analysis allows two independent switch points to be set and makes two programmable output signals available. The first output signal (channel 1) is proportional to the differential pres-sure and can be influenced by means of rooting or a table. The second output signal (channel 2) is proportional to the pressure and can be assigned optionally to the signal P+ or P-The nominal pressures of the integrated sensors and the differential pressure measuring range are set permanently ex-works and stated on the type plate.

Important features :
  • The individual pressures (P+, P-) can be dis-played
  • Switchable pressure units (bar, mbar, Pa, kPa, MPa, psi, InWc, mmW, mmHg)
  • 2 independent switching points with lots of con-figuration options
  • Zero-point correction, signal damping
  • 2 programmable output signals current/voltage
  • Characteristic curve spread and reverse with freely selectable offset
  • Characteristic curve implementation via table with max. 30 measuring points
  • Full parameter setting and measuring point protocol possible thanks to optional PC adapter EU03.
