Separate Free Core AC / DC LVDT Position Sensors

Macro Sensors’ HSDR 750 Series of 3/4 inch (19 mm) diameter DC-operated LVDT is designed for a wide range of position measurement applications. These are rugged hermetically sealed sensors, constructed entirely of stainless steel, and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed axial connector. The mating connector plug is supplied with the unit.

Macro Sensors’ HSE 750 Series of 3/4 inch (19 mm) diameter DC-operated LVDTs are designed for a wide range of position measurement applications. These are rugged hermetically sealed sensors, constructed entirely of stainless steel, and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed axial connector. The mating connector plug is supplied with the unit.

Macro Sensors’ SE 750 Series of 3/4 inch (19 mm) DC-operated LVDTs are designed for a wide range of position measurement applications. They use built-in electronics to provide the desirable features of an AC-LVDT, such as frictionless operation and dynamic response, with the added convenience and simplicity of DC input and precalibrated DC output. They are designed to operate in conjunction with PLCs, digital indicators, A/D converters, computer-based data processors, and QC data collection systems.

The SI 750 Series of 3/4 inch diameter, loop powered 4-20 mA LVDT position transmitters is designed for a wide range of position monitoring and feedback applications. Their stainless steel housings act as magnetic shields to reduce the effects of external AC magnetic fields, and their sealing meets IEC standard IP-62.

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' PRH 812 Series of AC-LVDTs are 0.812 inch (20.6 mm) diameter general-purpose LVDT linear position sensors that feature larger core-to-bore clearance than the standard PR 750 Series of AC-LVDTs. They were designed primarily for use in legacy OEM applications, and are cost-effective exact replacement LVDTs that offer the same form, fit, and function as competitors' products of the same size and range.

Macro Sensors’ HSA 750 Series of 3/4 inch (19 mm) diameter AC-operated LVDTs is designed for a wide range of position measurement applications. These are rugged hermetically sealed sensors, constructed entirely of stainless steel, and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed radial connector located near one end. The mating connector plug is supplied with the unit.

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.
