The
NDC Model 302 Krypton Beta Sensor is designed with accuracy,
precision, and safety in mind. Its ultra-high efficiency
detector allows it to outperform competitive Krypton sensors.
This innovative detector design allows NDC to use lower activity
sources. This design is safer to implement; and due to these
sources' lower shielding requirements, we can provide a lighter
weight sensor, thereby reducing long-term wear on the scanning
equipment.
The Krypton sensor is used when
a beta sensor is most applicable, and when the product weight
range is between 25 to 1200 grams per square meter. |

The
Model 360 Contact Caliper Gauge is ideal for an absolute
thickness measurement of products in the range of 1 mm (40 mils)
to 5 mm (200 mils), as long as contact of the product by the
sensor head is tolerable, and there are no ferrous metal
additives in the product.
The sensor head contains a
Variable Impedance Transducer (VIT) that senses the distance of
the lower reference head. This allows this sensor to read an
absolute thickness regardless of product composition, color or
density changes. |

The
Model 172 Dual-sided Laser Caliper Gauge is designed to measure
absolute thickness of products up to 15mm (0.4 in) thick,
independent of product density. This makes this sensor ideal for
profile measurements of products of inconsistent density.
The laser technology
incorporated into the design allows this sensor to be
insensitive to changes in product color and surface
reflectivity. The dual headed design incorporates lasers on both
the top and bottom to determine surface position on both sides
of the sheet. The design also incorporates a Radio Frequency
Sensor to compensate for any changes in the measurement gap
distance. By properly combining these three pieces of
information, the true product thickness is derived. |

The
Model 170 Single-sided Laser Caliper Gauge is designed to
measure absolute thickness of products up to 15mm (0.4 in)
thick, independent of product density. This makes this sensor
ideal for profile measurements of products of inconsistent
density.
A laser sensor detects the
precise location of the top surface of the material, while an RF
inductance sensor determines the position of a backing roll,
plate, or shoe that the bottom surface of the product is riding
on. By combining these two measurements, absolute thickness is
measured.
The laser technology
incorporated into the design allows this sensor to be
insensitive to changes in product color and surface
reflectivity. The design also incorporates a Radio Frequency
Sensor to compensate for any changes in the distance to the
backing roll. |

Through an arrangement with Voith,
NDC Infrared Engineering is pleased to offer the Voith Air
Caliper sensor for measuring paper thickness. With two versions
to offer, the Voith Air Caliper can measure paper thickness
ranges from 25 microns to 3000 microns. Its patented air bearing
system allows the sensor to either lightly touch or not touch
the web at all to make a thickness measurement, making it ideal
for lightweight or coated sheet measurement. |

The
Model 103 Heavy Weight Gamma Gauge is ideal for making thick
basis or coat weight measurements in the range of 5gsm to
25000gsm. Utilizing a Compton Photon Backscatter principle
allows this gauge to make a measurement from one side of the
product. This allows for a reduction in purchase and
installation costs. A reduction in maintenance cost is also
realized due to the long source life and light, small one piece
source/detector probe. And because gamma radiation is less
composition sensitive, this gauge provides a stable and accurate
measurement, without standardization or recalibration.

Traditionally, papermakers have positioned the “dry-line” to
obtain the proper drainage on the wire. However, larger paper
machines, elevated wires, steamy forming sections, and remote
control room locations make dry-line monitoring difficult for
operators. As top wires and additional fourdriniers are added
the dry-lines can disappear altogether.
The Gamma Sensor replaces
dry-line observations by providing an accurate indication of
stock consistency on the wire. Changes in the forming section
drainage are represented with greater accuracy and sensitivity
than a visual dry-line. Additionally, the sensor’s output may
also be used for closed loop control of refiners, head box
flows, and vacuum drainage boxes. |

The Model 105 X-Ray Fluorescence
Gauge provides an accurate way to measure thin, high atomic
number coatings on non-metallic films. This selective technique
has significant advantages in simplicity of operation, accuracy,
and reduced equipment costs. Competitive systems use
differential sensors, where many negative influences contribute
to a high degree of error and poor measurement correlation.
By tuning the sensor to the
fluorescence energy it is possible to detect thin coatings of
Zinc, Iron Oxide, or a variety of other high atomic number
coatings (see list below). Typically this sensor can measure
coatings in the range of 0 gsm to 25 gsm. |
