The Macro Sensors GHSE 750 Series of 3/4 inch diameter spring-loaded DC-LVDTs are designed for a wide range of position measurement and dimensional gaging applications. These rugged hermetically sealed sensors are constructed entirely of stainless steel and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68. Electrical termination is through a sealed axial connector; the mating connector plug is supplied with a unit

The Macro Sensors BBT family of 3/8 inch diameter pencil-probe type gaging offers ultra-precise measurement of dimensions in a wide variety of Q.C., SPC, and industrial metrology applications. They utilize a linear ball bearing assembly precisely fitted to a hardened-and-ground, non-rotating probe shaft to minimize radial play and the effects of side loading. This results in the probes' exceptional repeatability of 0.000006 inch (0.15 µm).

The GSA 750 series of short range spring loaded position sensors were developed for cost sensitive applications requiring LVDT reliability and performance. Available in ranges of ±0.10 inches to ±0.30 inches, these sensors offer the excellent measurement capabilities of an LVDT at very economical prices.

Macro Sensors’ PR 750 Series of 3/4" (19 mm) diameter AC-Operated LVDTs are general purpose contactless linear position sensors for both OEM applications and end user requirements. PR 812 and PRH 812 Series AC LVDTs are 0.812" (20.6 mm) diameter versions of the PR 750 Series and are designed primarily for use in legacy OEM applications and are not recommended for new designs. In most applications they are a cost effective form, fit, and function replacement LVDT for an OEM or user employing a competitor’s products of similar size and range.

Macro Sensors’ LVDT CD 375 Series of 3/8 inch (9.5 mm) diameter AC-operated LVDTs are small size contactless linear position sensors for both OEM and end user applications. They are available in full scale measuring ranges from ±0.025 inch (±0.63 mm) to ±1.0 inches (±25 mm) and offer 50% larger core-to-bore radial clearance, 0.012 inches (0.3 mm), than similar size units from competitors. The low mass of their cores makes these miniature LVDTs well suited for high response dynamic measurements. CD 375 Series sensors feature the high resolution, excellent repeatability, and low hysteresis associated with LVDT technology, as well as the highest sensitivity consistent with good linearity. The maximum linearity error for a CD 375 sensor is ±0.25% of full range output, using a statistically best-fit straight line derived by the least squares method.

The Macro Sensors GHSDR 750 Series of 3/4 inch diameter spring-loaded DC-LVDTs are designed for a wide range of position measurement and dimensional gaging applications. These rugged hermetically sealed sensors are constructed entirely of stainless steel and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68. Electrical termination is through a radially mounted sealed connector, which results in a much reduced installed length. The mating connector plug is supplied with a unit. The through-bore design allows for air purging of the sensor’s bearings to remove potential contaminants.

Macro Sensors’ HLR 750 Series of 3/4 inch diameter high reliability LVDT position sensors are specifically designed for use in gas turbine environments. Rated for operation to 300°F (150°C), these hermetically sealed AC-LVDTs are listed for Class I, Division 2, Groups A, B, C, D and Class I, Zone 2, Group IIC hazardous locations by Underwriters Laboratories.
