What are bore pumps:
A bore is a hole drilled in the ground that fills up with groundwater which can then be pumped out to use for drinking water for animals and livestock or irrigating gardens and farms.
Groundwater is water found beneath the land in pores and fissures in rock and soil. A bore pump, either above ground or a submersible pump and motor, is used to pump the water up and out for a range of uses.
Care needs to be taken when selecting a location to install a bore pump, ensuring safe and clean drinking water. Contact the team at EAS to help provide insight on ways to protect your bore location.
These pumps are very low maintenance, generally with a 10-15 year lifespan, with the infrastructure supporting the pump around 20-30 years. Some of the pumps can be setup with certain parameters, allowing constant pressure and flow. They can be setup for various applications suiting either mains or low pressure systems.
If you have a bore pump water supply system that is faulting
or causing issues, EAS can provide assistance with electrical testing and troubleshooting.
Your pump will require electricity to power it. Some applications may require a purpose-built pumping shed, complete with appropriate distribution valving, UV filtering, control equipment, general power & lighting.
EAS can provide you with a complete solution to installing a water bore on your property; from coordinating the drilling to setting up and installing your pump to ensure it is protected from power surges – giving you a long-term solution to your water needs.

Temperature is one of the most measured variables in manufacturing. Temperature plays a vital role in efficiency, energy consumption, product quality and safety.
Just some of the places that EAS has installed temperature sensors include:
There are various types of temperature sensors that can provide you with effective monitoring of temperature in your plant or process and EAS can assist you with selecting the right sensor for your needs.
The most commonly used sensors are Resistance Temperature Detectors (RTDs) and Thermocouples (T/Cs).
Thermocouples (T/Cs) are probably the most used method of temperature measurement. Thermocouples are contact sensors that are basically made up of two wires of different metals and joined at one end. Changes in the temperature at the junction of the dissimilar metals create a change in electromotive force (emf) between the other end and allow temperature to be measured.
There are many different types of thermocouples to fit a wide range of applications suitable for all industries, their appearances can be quite different.
But, as can be seen in the thermocouple diagram below, they all rely on the same basic principles and systems.
Two or more dissimilar thermocouple wires form at least two junctions within a circuit. One of these is always kept at a steady and stable temperature – usually lower, but sometimes higher, than the temperature at the measuring (‘hot’) junction.
A voltmeter connected to the circuit reads the current created by electromotive forces because of the temperature differential. This can then be used to give a precise temperature reading.
Resistance Temperature Detectors (RTDs) are also contact sensors. They work on the principle that the electrical resistance of a metal increases as temperature increases – this is known as thermal resistivity. RTDs are made of resistive material such as platinum, copper or nickel depending on the requirements of the process.
The resistance of Resistance Temperature Detector (RTD) changes constantly with the applied temperature so the temperature is quite predictable by measurement of its resistance. It is this property which allows Resistance Temperature Detector (RTD) to measure temperature accurately and consistently.
Each type of temperature sensor will work best in a particular set of conditions. The table below provides an indication of some of the conditions where thermocouples or RTDs are best used as well as the advantages and disadvantages each offers.
As you can see there are many factors that can affect the selection of the best temperature device for your application. EAS can help guide you in selecting the best sensor for your plant or process. Just get in touch with the team on 07 834 0505 or [email protected]

It sounds like Santa’s having a bad day with Rudolph. The Elf is afraid that that the reindeer will bite him, and without Santa around, Rudolph just can’t keep himself from eating the Snowman’s carrot nose.
What is Santa to do? He and his crew need to cross a bridge, but Santa has to act as a guide and cross with each one. This bridge is sure making his travels complicated! Darn that global warming!
Well, let’s think about it. On his first trip across, he has to take Rudolph with him, because he can’t leave the reindeer with either of the other two. Who knows what would happen to them?
So, you get the Snowman and the Elf on one side and Rudolph on the other. Santa comes back to the original side and now has a problem, because neither the Elf nor the Snowman wants to travel across to be alone with Rudolph. Santa, being the persuasive guy that he is, convinces one of them (let’s say the Elf) to cross with him. He has a solution, you see.
When he and the Elf get to Rudolph’s side of the bridge, the Elf is looking particularly worried. Santa tells him not to fret — he’s going to take Rudolph back with him.
He and Rudolph travel back together towards the Snowman — Rudolph has lots of energy from resting all year long, so he doesn’t get tired. This time, Santa travels across the bridge with the Snowman, leaving Rudolph behind on the first side and pairing the Elf and the Snowman together on the second side.
Santa has just two trips left to make. He travels back alone along the bridge, collects Rudolph and then everyone joins up together at the far side of the bridge.
Answer: 8 Animals. Elephant, Dolphin (trunk), Ant (Trunk), Horse, Dog, Cat, Mouse, Seahorse (tail).
Personally I don’t see an ant, I see a fish – but still got the same total!
Power factor is the ratio of active power (the power flowing to a system/appliance) vs the amount it uses to perform its function. A device’s power factor represents how effectively that device is using the power supplied to it – essentially its electrical efficiency.
Devices with high power factors make better use of the power being supplied to them than devices with low power factors. Power factors range from 0 to 1 where 1 represents 100% efficiency. A device that has a power factor of 1 is using all the power supplied to it.
Generally, a power factor of 0.8 or above is considered good. Lower than 0.8 and it should be corrected to save on consumption and comply with the requirements of the electricity network operator.
Other key reasons for improving power factor:
How do we measure Power Factor?
Power factor isn’t static – it fluctuates and can be influenced by changes in processes such as motor loading.
The power factor in a single-phase circuit (or balanced three-phase circuit) can be measured with the wattmeter-ammeter-voltmeter method, where the power in watts is divided by the product of measured voltage and current. The power factor of a balanced polyphase circuit is the same as that of any phase.
What causes poor power factory?
The main cause of low Power factor is Inductive Loads such as:
Unlike resistive loads (i.e., incandescent lights, electric heaters, cooking ovens), which involve a more direct conversion to useful work in the form of heat energy, inductive loads operate off of the magnetic field that is created by reactive power.
How can you improve your power factor?
While low power factor can cause a significant increase in your plant expenses and a decrease in your system’s efficiency, you can take several steps to help correct your power factor, including:
The simplest way to improve power factor is to add power factor correction capacitors to the electrical system. Power factor correction capacitors act as reactive current generators. They help offset the non-working power used by inductive loads, thereby improving the power factor.

Lighting in your workplace is critically important to your staff’s ability to accomplish tasks efficiently and safely. In addition, proper light levels prevent eye strain, which allow us to work comfortably for longer periods of time.
Light is measured using lumens and lux. Lumens are used to measure the amount of light being given out by a bulb. For example, a High Bay 200 watt LED light gives off 25,000 lumens.
Lux measures the amount of light reaching a surface. One Lux is equal to one Lumen per square meter.
While some lights may have a high lumen output when first installed, the level of lighting can depreciate quickly, this is another reason why LED lights provide a good replacement option.
The table below highlights the lux levels required to ensure efficient operation of your workplace.
|Computer workstations||300 – 500|
|Large item processing or assembly||300|
|Small item processing or assembly||500 – 1000|
|Inspection and testing||500 – 2000|
|Packing & Dispatch||300|
If you are concerned that your lighting is not at the required level EAS can conduct lux measurements to assess your current level of lighting and where improvements may be required.
This can also provide a good opportunity to consider upgrading to LED lights which also offer the benefits of:
This means the LED light is 56% more efficient than its Metal Halide counterpart and this efficiency only improves over the lifetime of the fitting as the lumens in a metal halide light depreciate quite rapidly while the LED lumen output hold steady.
With LEDs there is also less chance of glass breakage over essential product areas such as bulk stores and process areas in your plant.
