Zerotronic Sensor

Zerotronic Sensor

Zerotronic sensor is an Ultra-Precision Angle measurement sensor using the latest precision technology and digital technology.
It boasts of high accuracy and stability even in high temperature and high humidity environments because it is a new technology inactive gas sealed sensor. Zerotronic is the most appropriate sensor for constructing a high accuracy long period monitoring system.
By connecting it to the Intelligent display Level Meter 2000 and computer, it can be used in a wide range of applications like Precision machinery, Precision machine tool, generating plants, ground deformation monitoring, bridge monitoring, etc.

The normal distance between the sensor and computer is 15m, however it can be extended up to 1000m using an intermediary transceiver/converter (T/C).
It is possible to connect up to 32 pcs of zerotronic sensors.

Zerotronic sensor

An ultra precision level made by Swiss company WYLER AG.
The sensor head pendulum is completely covered by ceramic baord to enclose inert gas. It is durable and high accuracy is maintained despite changes in external temperature and humidity.

  • For monitoring variations in the head column of machine lathes.
  • For measurement of Important security facilities, bridges, buildings, dams, tunnels, generating stations standard decsk, adjustment decks, etc.
Special Features

  • It is very strong and stable for use in outside environments.
  • There are 5 Measurement Ranges that can be used depending on the application.
  • Static or dynamic angular variation monitoring, measurement, display, and data processing are possible.

Display unit Blue Meter SIGMA

The Blue Meter SIGMA is a revised and updated version of the Blue Meter intelligent type display instrument. It can be connected to various measurement instruments made by WYLER like (Zerotronic sensor, Blue Level, Clinotronic etc.)
There are 2 Detector input ports [A-B, C-D differential display], [A=X Axis, B=Y Axis 2D display] [Bubble tube type display] etc. can be selected. A variety of display types can be selected depending on the application.
Using RS232C output, it is possible to output the measurement data to a computer without loss of data.

  • It can be used as a remove display unit for the detector or as an interface between the Detector and computer.
Special Features

  • Data transmission to a computer is possible with RS232C output.
  • By transmitting (connecting) 2 sensors to the display unit, differential display, 2D display an other various types of display are possible.
  • In addition to Zerotronic sensor, it can connect with Blue Level and Blue Clino.
  • This product conforms to CE Marking.
