MTP - Continuous Strip Thickness Gauge with Automatic Drive

This high-endurance heavy-duty gauge is designed for precision continuous online contact measurement of metal as well as non-metallic strip thickness (continuous thickness mesurement). Types: MTP-1301A, MTP-2001A, MTP-3001A.

Tactile thickness measurement

There is the company´s own microwave technology with no electronic components, coils and ferrites inside the tactile highly resistant sensors. The sensors are absolute, very stable, with linearity of < 0.01% and resolution of 0.1 µm. Therefore, the thickness gauges do not require zeroing before/after measuring that tends to be a source of very inaccurate measurement if it is zeroed with impurities between contacts. Thanks to cooling the sensors and contacts through the sensor body, strip thickness can be measured at temperatures of 250°C with a temperature dependence of ≤ 1 µm/200°C without need of heating the measuring head. Measuring contacts made of sintered diamond are typically used for decades of years without replacement even in heavy-duty environment.

The gauge sliding in the operating position on strips of varied lengths and the gauge operation monitoring is carried out by SIEMENS automatic drive using pneumatic system. The design of the diamond contacts, which are permanently touching the measured strip, secures they do not impair the appearance of the material and have long service life. The pneumatic thrust of the contacts on the strip can be continuously controlled.

This continuous gauge was developed as an absolute measuring device requiring no mechanical readjustment for the nominal thickness of the measured strip and its absolute measuring capability allows to use it also for precision calibration of other (e.g. contactless) gauges during the production process.

The control unit enables:

digital thickness on 7" touch panel display
analogue display to show the deviation from the set nominal thickness
setting and monitoring of lower and upper limits
digital calibration of the gauge
control of moving head into strip line
anlogue outputs for AGC ± 20 mA (± 10V; 4 - 20 mA)
serial data output module (RS-485, PROFIBUS, PROFINET,...)

Features:

absolute digital display of the measured thickness
independence of the measured material type
no mechanical adjustment of the gauging head for nominal thickness
easy operation
5 years warranty on diamond contacts

Optional accessories:

industrial PC with PP-VIZUAL statistics processing system
