Meech International is using Emballage 2014 as a platform to showcase its new Distance Sensor and Feedback System, the latest enhancements to the Hyperion series of electrostatic control systems. The two extensions, compatible with the 971IPS and 929IPS ionization bars, were developed to monitor and control electrostatics with greater accuracy in a variety of applications, including packaging and labelling.
“To provide our customers with the best possible electrostatic control solutions, Meech is committed to continuously updating its technologies, to which customers contribute significantly through their feedback,” says David Rogers, Head of Electrostatic Control at Meech. “In this respect, we are very pleased to demonstrate our latest innovations at a prestigious exhibition like Emballage.”
Distance Sensor
The Distance Sensor is used in combination with the Meech 971IPS CC bar for long-range ionisation. The main function of this extension is to allow the frequency to change as the distance to the statically charged surface increases or decreases. This means the sensor adjusts the neutralization based on the varying distance to the static surface.
The Distance Sensor is mounted directly onto the 971IPS ionisation bar and comes with a cable ranging from 300 to 3000 mm in length. Its intelligent and innovative design ensures that the sensor does not affect the bar’s performance, regardless of its position relative to the bar’s electrode tips. Once the sensor is connected, it overrides the bar’s frequency setting and adjusts it according to the detected distance.
“To ensure the most effective control, the Distance Sensor selects the optimal output frequency based on the proximity to the material. This is particularly useful during winding, where the distance to the surface decreases during the winding process,” says David. “Furthermore, automatic frequency adjustment ensures optimal electrostatic control throughout the process.”
Feedback System
The second innovation in the Hyperion series is the introduction of “feedback-capable” ionisation bars, which offer high-precision electrostatic control in production environments and can transmit voltage levels for remote monitoring.
Feedback-capable systems are equipped with a 3-pin M8 connector and updated software. By connecting a standard, remotely operated industrial voltage sensor and positioning it above the strip, a feedback control circuit is created. The sensor’s output signal informs the Hyperion bar whether more positive or negative ions are needed to achieve complete and accurate neutralisation of all charges on the material.
“It’s important to ensure that the level of electrostatic charges on a surface is kept to a minimum, especially those entering hazardous areas, to avoid the risk of solvent ignition,” explains David. “While our ionization bars perform this function reliably, Meech has extended this technology by integrating an electrostatic voltmeter sensor, which achieves a higher level of electrostatic neutralization.”
With a cable length of approximately 5000mm, the Feedback Sensor can be installed behind the ionisation bar, in a position not directly controlled by the electrostatic system. When installed at a distance of 50mm, the sensor has a measurement range of -20,000 V to +20,000 V.
“We are always looking for ways to improve our electrostatic control systems,” says David, “and the introduction of these two new extensions is an important step forward for Meech’s Hyperion series of electrostatic control products.”
He concludes, “Introducing these new products allows us to demonstrate how our constantly evolving field of electrostatic control technologies is capable of meeting the needs and requirements of the packaging industry.”
