Loadcells

Unbeatable range and quality 

Our know-how and experience in weighing applications allow us to offer one of the most complete ranges of loadcells on the market.

loadcell
The heart of any weighing system is the load cell. A load cell is an electrical instrument that is used to convert a mechanical force into an electrical output signal.

In order to get the most benefit from a load cell, a thorough understanding of the technology, construction and operation of this unique device is required. In addition, it is imperative that the correct load cell is selected for each application. With our experience, EMC can assist with load cell selection including the correct capacity, accuracy class, and environmental protection

Our comprehensive range includes aluminium, alloy steel, and stainless steel loadcells covering a wide measurement range up to 1000t. Our suppliers such as Scaime, Vishay, and Thames Side are amongst the foremost loadcell manufacturers in the world.

The majority of our load cells meet international regulations and standards, providing optimal safety and performance assurances for your applications.

Features include:

  • Capacities range from 200g to 1000 tonne 
  • Single Point, Bending Beam, shear beam, double-ended shear beam, Tension & Compression Models 
  • Aluminium, Tool Steel and Stainless Steel models
  • Ingress protection levels ranging from IP65 to IP69K
  • Many models available with Hazardous Area Certification (IECEx/ATEX)
  • OIML Certification

Silo and Tank Weighing
Reliable and accurate tank and silo weighing solutions alm2

Weighing offers high accuracy and repeatability when measuring the contents of tanks, silos and other vessels. EMC’s Vessel Weighing products combine to provide simple and economical systems which are supported by EMC’s extensive experience, and essential specialist engineering advice to ensure a successful installation. 

Typical installations include the weighing and supporting of large milk powder and flour silos, vegetable oil tanks, small tanks for mixing and batching applications, hygienic and hazardous environments, etc. 

The size and type of vessel, its support structures and pipe connections, movement during filling, environmental aspects, seismic restraints etc, are all factors that have to be considered in the design of a Vessel Weighing System, as they can have a significant impact on the accuracy and reliability. 

Loadcell Mounts provide a ready-made solution for tank and vessel weighing. In many applications, installation is simply a case of bolting the Mount between the floor and vessel leg, however, some installations require more engineering to ensure reliability and accuracy.

Only the highest quality loadcells, from the world’s leading manufacturers, including Scaime, Vishay & Thames Side are fitted in EMC Loadcell Mounts to ensure the best in reliability and accuracy (from ±0.017%).  tank

Features include:

  • Capacities range from 20kg to 100 tonnes or more, and models include: 
  • Double-ended shear beam 
  • Standard shear beam 
  • Compression 
  • S-beam 
  • Bending beam

Loadcells are available in various materials such as Tool Steel and Stainless Steel and with specifications to suit the specific application and environment, e.g: 

  • IP66 / IP68 sealed models for hygienic or wash-down applications 
  • with hazardous area certification (IECEx Approvals)
  • with OIML certification for use in Trade Approved applications, etc.
Chlorine Drum Weighing

Safe and accurate chlorine dosing

EMC manufactures rugged Chlorine Drum /Cylinder Weighing Systems that are specifically designed for the needs of Water Treatment Plants. They are also suitable for monitoring applications at booster stations, wellhead, and various industrial processing plants. 

Systems include a frame for weighing large 920kg chlorine drums and a scale for weighing the smaller 70kg capacity cylinders. 

Also included is an EMC ModWeigh Transmitter and Indicator so that net drum contents can be monitored at all times. This can be installed as a scale mounted unit or in a separate remote panel. The ModWeigh System provides a local indication as well as transmission to a PLC or Scada system via the 4-20mA analogue output.

  • Low-level alarms
Belt Weighers
Rugged design with proven performance image22

Our EMC Belt Weigher Systems (also known as Belt Scales) provide a simple and accurate way to measure the flow rate and total tonnage of bulk material passing along a conveyor belt. 

A system includes: 

  • Single, Dual or Multi Idler Beltweigher, with integrated loadcell/s to measure the load 
  • Tacho Assembly to measure belt speed
  • ModWeigh MW95A Processor to calculate flowrate (t/hr), totals, etc

Proven experience:

We manufactured our first Beltweigher in 1973 and have since supplied over 500 throughout New Zealand and worldwide. This wealth of practical experience provides you with mechanical design and rugged construction that has been proven in many industries and applications. An essential component of any weighing system is a reliable and economical processor. We have designed and manufactured Weighing Processors for over 40 years and our ModWeigh Series is recognised internationally for its quality and ease of operation. Our experienced staff and fully equipped workshops ensure that full local back-up and service is provided throughout New Zealand.

If your industry is mining, quarrying, cement, fertiliser, chemical, steel, timber, or food processing, Belt weighers are commonly used in production and inventory monitoring.

Belt Weighers are generally used for:beltnw1

  • Bulk material measurement
  • Bulk inventory control
  • Production rate measurement
  • Production totals
  • Continuous blending systems
  • Flow control and blending

Some of the diverse products that we have accurately measured with our Belt Weighers include:

  • fertiliser, coal, sand, iron sand, aggregates
  • wood fibre, wood chips,
  • vegetables, tobacco
  • detergent powder, etc.
Weighfeeders

Custom made in New Zealand to suit your application

EMC Weigh Feeder Systems provide a simple and accurate way to measure and control the flow rate of bulk material passing over a belt. They transport and weigh bulk material from a hopper on a driven belt. The weight on the weigh section is measured by a high-resolution loadcell. Our ModWeigh processor computes the flow rate based on the weight and measured belt speed. The flowrate is then regulated to the desired value by varying the speed of the belt.

Our standard systems include: 

  • 3 idler weigh section, with integrated loadcell 
  • Direct drive sealed Gearmotor 
  • Belt speed via tail drum encoder 
  • ModWeigh MW96A Processor to calculate and control the flowrate (t/hr), etc
