ZED82B series of high-precision displacement measuring instrument chassis system use modular rack mode to provide personalized building block measurement solutions.
ZED82B Measuring Module
The ZED82B highprecision displacement measuring system is packaged in a modularized rack format for mutlichannel displacement, run-out, and position measurements. It is ideal for industrial, laboratory, and production test applications.
The 3U-by-7T Eurocard measuring module is the fundamental component of this non-contact measuring system, along with the sensors. This module — which conditions the sensor signal — contains the inductive bridge and signal conditioning circuits that produce the measurement output, a linear voltage proportional to the physical displacement of the target relative to the sensor.
ZED82B series has 27 kinds of sensors to choose from.
There are two types of multi-channel 19-inch chassis:3U / 94HP (maximum chassis); U / 42HP (half chassis).
MAIN FEATURES

Sensor Cables
Sensor cable extension
Most sensors can handle longer cable lengths, although increasing the cable length can and will affect some performance specifications. Shorter than standard cable lengths are also available. Call an apps engineer to discuss your particular requirements.
In-line cable connector splice
Many sensors come with integral sensor cables. Routing this cable in some applications is difficult and something you only want to do once. Including an in-line connector splice in the cable, near the sensor itself, allows for easy sensor replacement should the need arise.
Hermetic in-line connector splice
Some applications pass the sensor through a pressure boundary, most commonly a vacuum chamber wall. We offer an in-line hermetic bulkhead splice for these applications.
Standard published ranges are based on meeting a set of performance specs. Custom calibrations are possible to meet specific application needs. Contact a ZSY applications engineer if a custom calibration is desired.
Target material
Unless otherwise specified, nonferrous systems will be calibrated with an aluminum target, ferrous systems will be calibrated with a 4130 steel target. If your target material is significantly different in conductivity and/or permeability it may be best to calibrate using the same material as your target.
Temperature compensation
When the standard thermal sensitivity of 0.1%FS/°F is not enough, a temperature compensated calibration can be performed that will improve the thermal sensitivity to 0.02%FS/°F. This is accomplished over a customer specified 100°F range with the upper limit of that range<150°F. Larger ranges and higher temperatures are also possible on a best effort basis.
Besides the standard 0-10VDC output, theZED23 offers a 4-20mA output and a differential 0-10VDC output.
Log Amp Bypass
When extremely short range calibrations are required/desired, bypassing the log amplifier reduces noise improving performance.
Power supplies
P-3400
SERIES For economy and reliability in a modular power supply, P-3400 Series is unsurpassed. The regulated ±15 Vdc output is compatible with all eddy cuurent measuring systems requiring an external power source, or for any other use requiring a ±15 Vdc output.
The P-3410 features 100mA output with one terminal block, and will power one measuring channel. The P-3450 features 500 mA output with three terminal blocks, and will power up to six measuring channels.
P-3600
SERIES Compatible with the ZED23 and ZED24, these switching power supplies offer clean, reliable, DC voltage output in a small, DIN-rail-mount package.
Calibration fixtures
Calibration of a displacement measuring system verifies that the system output relates to a known physical displacement. Calibration of a ZSY eddy current measuring system requires the ability to position a target at specific locations relative to the range of the sensor.
All ZSY balanced bridge-type measuring systems are calibrated prior to shipment, and ready to use out of the box. Certain requirements can necessitate the need to recalibrate the system:
> Sensor replacement due to physical damage.
> New calibrated range requirements.
> Sensor/bridge change to different model.
> Calibration check/recalibration program.
Proper sizing of a calibration fixture is based on sensor diameter. The calibration fixture has a recommended maximum sensor size for use, based on the physical size of the fixture that sets the radial distance from the sensor to the fixture itself. When a sensor larger than the recommended maximum is calibrated using the fixture, the performance of the system can be affected.
This fixture can be used with virtually any inductive type sensor manufactured in a cylindrical housing, and is provided with a rotating-shaft micrometer head with an aluminum anvil/target. If a different target material is desired, a suitably-sized piece of the target material is attached to the existing anvil.
For larger diameter sensors, ZSY offers hard impact precision ceramic calibration spacers. The set includes seven spacers, 1.5 inches in diameter in the following thicknesses: 0.050 inch, 0.100 inch, 0.200 inch, 0.300 inch, 0.400 inch, 0.500 inch and 1.00 inch. Each spacer may be purchased separately, and a 0.025 inch spacer is also available.

ZED82B is a non-contact, linear, analog displacement measuring system. The system operates on a traditional inductive bridge circuit. This easy-to-use, versatile system can be utilized for precision static and dynamic measurements of conductive targets.
The sensor coil makes up one or two legs (depending on single or dual coil sensor) of a balanced bridge network. As the target changes position within the sensor field, the bridge network senses impedance changes in the sensor coil. These changes are converted to an analog voltage or current signal directly proportional to target displacement.
These single ended systems were developed to satisfy an extremely wide variety of measurement applications for both ferrous and non-ferrous targets, including: General purpose linear position measurement, Laboratory, research, development, and testing Metrology, Factory process control, Machine monitoring and control Shaft run out and vibration where longer sensor cable lengths are required, Applications for differential bridge systems include: Steering mirror position, Pointing and tracking in night vision and laser systems, Control systems for active vibration monitoring and control systems, Photolithography stage positioning and control.
