Eddy Current Displacement Sensor EZ GAP®
Description
EZ GAP is the eddy current displacement sensor to measure the distance to iron, stainless and aluminum.
ADVANTAGE
High environmentally-resistant sensor
Sensor's materials are used with SUS and PPS.
Clears the IP protection rating 67, and withstands the temperature of up to 105℃(Option:130℃).
Proves the sensor's ability under the poor environment.
Easy calibration setting
The corrected points can be set from 2 to 11 points freely at your desired sensor position. As the number of corrected point increases, the linearity
errors become smaller.(linearity error :±0.15% F.S.)
The nonmagnetic metal (SUS 304, A5052) object also can be detected by the sensor.
Reducing the temperature drift
The temperature drift is less than ±0.015% F.S./℃ by the temperature drift adjustment function.
(within a range less than a half of the rated detection range)
Temperature measuring function
The temperature at the sensor head can be monitored.
This function makes soundness of the sensor check , so the products can stabilize the quality.
Extendable up to 20m
The sensor cable can be extended up to 20 m.
It is easier to wire. Each connector is plated with gold which gives resistance to improper contact.
Improved the maintenance efficiency!
It can be replaced individually even if the sensor or amplifier has a malfunction.
Touch roll is available
Touch rolls introduced in the application are available at NSD.

*1: L1: Sensor interconnecting cable length, L2: Extension cable length
*2: The detection object material is S50C, FC250, or SUS 430.
For the other object materials, refer to the specification and instruction manual.
(The rated detection distance is shorter than above materials, and the temperature character is more increased.)
*3: The “range less than a half of the rated detection range” is, for example, 0 to 6 mm range when the rated detection range (F.S.) is 0 to 12 mm.
