Non-Contact Speed And Length Measurement Of Tread

Thursday, 11 July 2024

The sensor for special materials For sensitive, soft, or smooth surfaces, customers from factory or logistics automation require non-contact measurement options for the length, speed, and position of continuous webs and blanks. "Product testing and field trials have already shown the Speetec to be reliable even when measuring highly reflective, dark-black or uneven surfaces. Measurement problems with traditional contact measurement devices: - Lack of accuracy due to slippage of tactile driven encoders (Wear, contamination, adhesion problems, accelerations, …).

Non-Contact Speed And Length Measurement Methods

Temperature range: -10 °C - 70 °C... ROS-W (Remote Optical Sensor with tinned wire termination) and ROS-P (Remote Optical Sensor with 1/8" phone plug termination) are threaded stainless steel remote optical sensors with... For thickness measurements that require nanometer accuracy, capacitance sensors provide excellent linearity. The gauges are extremely easy to install, set up and integrate into an existing control system, or can be used as a stand-alone system. Non-contact speed and length measurement methods. In most cases the product is contacted by a wheel and the wheel rotation is translated into encoder pulses, these pulses are counted by an electronic counter or by a PLC counter. Old style wheel followers and shaft encoders are problematic due to slippage between the product and contact wheel or shaft. Speetec offers a new possibility to measure without slipping, without measurement reference or markings and also without wear unlike contact systems. Measured values are output via the TTL or HTL interfaces common in the encoder world, making integration easy. 05% and repeatable to better than 0. Tenter Frame Shrinkage Measurement – µSPEED.

There are two basic types of linear displacement sensors: contact and non-contact. These errors can be large enough to create wide variations in tension, causing a break during splicing. A contact encoder riding on the product reveals wheel wear, slippage and calibration issues. ELOVIS also offers calibratable length measuring systems in accordance with the European Measuring Instruments Directive MID 2014/32/EU. The result was an error in calculated surface speed at the time of splicing. Non-contact speed and length measurement of pressure. Temperature range: -15 °C - 100 °C. Measuring the material via a direct measurement method reduces the possibility of slippage. Large measurement distance tolerance range ⇒ Thickness-independent measurement. Direction Detection. Polytec's compact velocimeters allow you to contactlessly measure both the length and the velocity of continuous material and piece goods.

Non Contact Measuring Systems

Are available with industry-standard communications interfaces fitted either as standard or as an option. The result was a significant reduction in tension variation during the splice, which eliminated breaks due to mismatched speeds. When considering indirect measurement, it is necessary to consider the impact of slippage. High resolution in combination with speed... Comparable systems are much slower here. Non contact measuring systems. At these high speeds, however, typical methods of calculating speed may not suffice. Ideal for inline measurement. The elongated shape of the window and the box with rounded edges indicate the direction of measurement and assembly. All Proton Products Speed & Length Gauges: - Provide high-speed, non-contact, solid-state laser doppler speed and length measurement with no slippage, drift or mechanical wear and greatly reduced maintenance compared with contact wheel / roller systems. Automotive industry: - Automotive industry (measurement of driving distance for cars, trucks, rail vehicles, trains, sports vehicles, …).

Wheel circumference 300 mm with O-ring made from NBR70. They measure... Non-contacting two-channel speed sensor with brass threaded tube, difference-Hall or inductive-magnetic principle • Due to its design and its approvals especially suitable for shipbuilding... The following sections provide a brief description of each technology along with images of MTI products and links where you can find more information. ProSpeed laser sensors – Measure length and speed in production processes without contact. The speed sensor may be used with many different types of off-the-shelf hardware such as timers, counters, or digital tachometers. Laser triangulation sensors are ideal for measuring moving targets in high-speed applications because they have a high frequency response. Via external direction signal. This error could be great enough to cause a mismatch in speeds resulting in significant variations in tension causing a break during splicing. All outputs are integrated within the Sensor. Error of measurement.

Non-Contact Speed And Length Measurement Of Pressure

Laser rangefinders and laser sensors are suited to non-contact dimensional, especially length measuring. Measurement of elongation and shrinkage: Differential length measurement for determining the elongation and shrinkage of materials in the machining process. Non-contact laser measurement gives converters the competitive edge, enabling them to control product quality while realizing significant production savings. 0%, saved approximately $40, 000 per year and realized a ROI in less than three months. As far as managing product length, the manufacturer is faced with problems such as: - Shipping excess material due to slippage. Contact vs. Non-Contact Measurement: Examples of Each. Speed Measurement Range. A manufacturer of corrugated boxes needed to accurately control the speed of product during normal production and "tail-out" situations. All of these contact sensors provide a continuous output of the distance being measured, such as a voltage that is proportional to the distance, or a digital indication in engineering units such as inches or meters.

As the second generation series, the SL and SLR mini are designed for industrial applications and material processing lines; compatible with almost all moving materials including web, wire, plate and sheet. What do you think of this article?
