NewTek Sensor Solutions introduces the MBB Series of Ultra-Precision Dimensional Gauging Probes engineered for highly accurate and repeatable measurement of dimensional parameters in a variety of quality control, industrial metrology, and inspection equipment applications.

Offering excellent linearity, great precision and infinite resolution, these spring-loaded AC-LVDTs are ideal for use in roundness measurements, automotive testing, metal component gauging and materials testing.

The MBB Series Gauging LVDT Probes feature a stainless-steel probe assembly and 8 mm diameter housing protected to IP-65. High-precision linear ball bearings provide for smooth probe movement without stiction and excellent repeatability.   Incorporating a linear ball bearing assembly fitted to a non-rotating probe shaft, the MBB Series Gauging Probes produce an output voltage linearly proportional to the probe’s shaft position with minimal radial play. The use of an AC-operated LVDT for probe shaft displacement reduces errors due to friction, resulting in a highly precise measurement of the position of a target surface.

More precise substitutes to mechanical position indicators and digital dial gages, the MBB Series of LVDT-based Dimensional Gauging Probes are extremely reliable with greater than 100 million cycles with linearity of less than 0.05 per cent of full range.  MBB Series GaugingProbes are available in three standard ranges: ±.040 in (±1.0 mm), ±0.100” (±2.5 mm) and ±0.200” (±5.0mm). Units are available in 0.315 in (8 mm) and 0.375 in (9.5 mm) diameters.

NewTek offers DC-operated signal conditioners such as the  NTC Qwik-CAL Signal Conditioner that combine with the MBB Dimensional Gauging Probes to create a complete linear position gauging system that outputs statistical quality control data on manufactured parts.  Mounting several gauge probes in suitable fixtures also creates a system for “go/no/go” inspection of complex mechanical parts.
