The Different Dielectric Measurement Methods

Dielectric testing services are an important measure to improve the quality and control of insulating conductors and electronic parts. There are a number of dielectric testing techniques and services to choose from. Performing the appropriate measurement will ensure accurate results

Coaxial Probe – When testing for the permittivity of a material, coaxial probe is the proper technique. This is done by pressing a metallic probe against the material or soaked in a liquid solution to gauge reflection coefficient that verifies the permittivity. This simple approach allows the user to gather data across a broad range of frequencies.

Transmission Line – This method involves putting a sample on a waveguide. Next, assess intricate scattering parameters using a VNA analyzer. It applies both reflection and transmission to collect measurements with greater sensitivity than the coaxial approach.

Free Space – Free space can test electricity over a diverse range of frequencies. This is performed by placing large, flat samples of materials under extreme heat and in a hostile setting for a dielectric testing. This method allows you to get reflection and transmission coefficients without any contact. Moreover, it enables you to evaluate both electrical and magnetic properties of the material.

Resonant Cavity – This technique gathers measurements with high accuracy and high-temperature support. It enables you to get accurate data with dielectric loss materials. The method applies the concept of a resonant frequency shift of a tuned cavity when a loss material acts as a resonator.

Parallel Plate - In this method, the tester needs to sandwich the dielectric item between two electrodes to create a capacitor. Then, using an LCR meter or impedance analyzer measurements are collected along with a dielectric test fixture. This is the preferred dielectric technique for testing low frequency materials.

Planar Transmission Line - This method uses a microstrip line to test materials in RF and microwave components. It is appropriate for industrial purposes due to its compact feature. In this testing approach, dielectric measurements are inferred from a shift in permittivity using appropriate expressions.

Rapid Response to Your Hydraulic System’s Overheating

Overheating is a common issue encountered within hydraulic equipment. And we know from experience that the overheating situation will shut down the exact wrong piece of your equipment at exactly the wrong time. We specialize in putting you, your business and your equipment back to work ASAP via rapid response deployment of our team of certified hydraulic repair technicians.

Whenever you encounter overheating issues within your hydraulic system, keep in mind that there are two ways to solve the problem. The first thing to do is to shut down the machinery and take a moment to think through the issue and eliminate the immediate threat of permanent damage to your equipment. You then must be able to restart the equipment with either a lower heat producing load or improved dissipation of heat. Maybe you can self-help this.

First thing to do is to inspect the fluid level of the reservoir. When it is low than the recommended level, refill it to reach the right level since hydraulic system eliminate heat through the reservoir. Make sure there are no accumulation of dirt that is blocking the airflow. Then, investigate the core of the heat exchanger and make sure there's no obstruction since its ability to remove the heat is reliant on the flow rate, hydraulic temperature and the cooling air or water that is flowing within the exchanger. You may also need to replace the cooling circuit parts if it is not working well.

Check how heat exchange perform by using an infrared thermometer as long as you know the actual flow rate of the hydraulic fluid in the exchanger. Check also the temperature of the oil that is coming in and out the exchanger and substitute the values applying a formula provided by a certified hydraulic company. A decreasing pressure will result to heat production. If internal leakage is present in any of the system parts, it will boost the heat load on the system, causing it to heat up excessively. There are multiple rationale behind this occurrence which includes a leaky cylinder draining a high-pressure fluid over its piston seal to a relief valve that was not properly adjusted.

Consequently, you need to change any of the heat generating parts that is worn out, and there are instances when a professional technician is required to figure out the component that is inflicting the issue. Regardless of the cause behind an overheating hydraulic system, it is imperative to turn it off immediately to get to the bottom of cause and mend it. Persisting to run it at inappropriate temperature is unsafe and will surely damage your equipment. It's important to be proactive when you notice an overheating system. Find the cause right away in order to address the problem.

Or, simply trust the professionals like use here at ETS. We’ll simplify your life, make sure your equipment is repaired in the shortest time possible, and put you and your equipment back in business.

Common Accidents Associated With Aerial Lift

Joseph Coupal - Friday, April 10, 2020
ETS - Aerial Lift  - Boston, MA

Accidents are common with poorly maintained aerial lifts. Lift accidents are caused by faulty outrigger, wobbly guardrails, hydraulic leaks, defective brakes, and a host of other failures. Lift-related accident risk is mitigated dramatically via professional aerial lift routine maintenance service. Here are just a few documented accidents associated with poorly maintained lift equipment:

  • Tip-over incidents usually happen when the operator erroneously position the lift. It also takes place when you hit into an immovable object or the machine malfunctions. Ensure that you position the equipment on level ground far from divots, avoid other objects and make sure the equipment is working properly.
  • Fall accidents usually happen when a worker bend too much over the guardrail. Most of the time it is due to wrong distance estimation when reaching the next window or cable. To resolve this common incident, operator must be aware of the risk when operating an air lift at excessive heights. Always ascertain to move the aerial platform at the right position. Regular maintenance is required to ascertain your equipment can be properly maneuvered.
  • Electrocutions take place when operators run across an overhead cable or power line. Before turning on your engine, check your surrounding for any obstructions above you. Lower the lift when running beneath wires and avoid moving to hazardous areas. Assume all cable wires live.

Moreover, read the manual for your equipment’s horizontal and vertical reach limits. Stay within this limit for safety.

When it’s time for you and your business to bring your lift operations to a documented safe state, seek aerial lift testing services from the Boston-area professionals who’ve been doing this for decades now. Contact ETS Inspection and Testing Services, and let’s get it done!

ANSI Standard for Aerial Lift Safety Check

Joseph Coupal - Tuesday, March 31, 2020
ETS Inspection and Services, Boston, MA

The American National Standards Institute defines the mandatory aerial lift maintenance and repair standards that all lift equipment companies must adhere to. Companies must remain ANSI compliant not only for the purpose of ensuring safety operations but to prevent costly penalties and legal implications as well.

The A92.6 ANSI policy serves as a reference that influences manufacturing and design, rebuilding and reconditioning of all aerial equipment. The guidelines impact not only those who own the equipment, but certainly those who operate, inspect, maintain, and repair the lift equipment.

The annual and frequency inspection directives are listed in the guiding principles and the guidance and emphasis is clear that only certified technicians are to perform these activities. The personnel must be trained and certified in the care of the exact or models of similar function and capability. The inspection must take place at least every 90 days or after 150 hours.

Annual inspections must not exceed 13 months from the date it is previously checked. Plan the scheduled maintenance according to your operation hours and the type of service the aerial lift is employed. ETS can perform this routine upkeep for your machines. You can count on our expert technicians to service your equipment to the most stringent quality standards.

Contact ETS Inspection and Testing Services to help you comply with the regular maintenance of your fleet based on ANSI Standards.
