In all types of operations from paper manufacturing to films, steel or winding operations, there is the need to have the process carefully controlled. When precision in the tension on the material is critical, it will be essential to have a tension indicator that is accurate, dependable and rugged enough to stand up to demanding work environments.
These devices are carefully designed to suit the specific equipment. The size, dimensions, and capacities of the different indicators will be important to compare, but it often the dependability and durability factors that are most considered factors after accuracy. In specialized processing where heat, humidity, and vibration are a concern, the durability factor is often the primary consideration.
Analog or Digital
There are two different types of tension indicator models. One is the analog model, which will provide a metered type readout on the indicator. This doesn’t mean a simple system and top models will offer features and functions such as tare adjustments, filtering, balancing and summing circuitry, tension monitoring options and controls, full meter scale adjustments and a stainless steel enclosure.
Digital tension indicator units feature the same type of construction and features, but they utilize a digital readout that provides specific tension rather than the gauge type readout. With top manufacturers the indicator decimal point specification will be pre-set, allowing for the precision display required.
Tension Range Measured
Different applications will require a different range of tensions. For example, in the processing of plastic films, extremely precision tension control is required. Even slight variations can result in wrinkles or stretch of the plastic that can render the roll useless in specific types of packaging.
These tension controls and indicator system need to be able to adjust to meet the requirements of the different plastics. Look for systems that offer adjustable tension load ranges that work for your current processing needs and those of the future.
