LVDT Linear Position Sensor
Macro Sensors (Pennsauken, NJ) has introduced the
HPGS series Hermetically Sealed, High Temperature
LVDT Linear Position Sensor, featuring a screw-on radial
connector that provides high sensor reliability and long
life under the high vibrations and dirty environments of
nuclear, gas, and steam power plants. Features include:
■ A secure connection.
■ A through-bore design that permits access to either
end of the LVDT core.
■ A shorter installed length compared
to units of the same range with axial
■ The ability to withstand exposure to
mild radiation ( 3 x 107 Rads) and
immersion in pressurized fluids.

for High Volume OEM Use
Ocean Optics (Dunedin, FL) has expanded its Spark
spectral sensor range with the addition of the Spark-DET-VIS.
The tiny sensor-only version weighs less than 1 g, making
it the smallest spectral device on the market. The Spark-DET-VIS delivers full spectral measurements over the visible
wavelength range of 380 to 700 nm. Features include:
■ The ability to measure simple absorbance, fluorescence,
and emissive color.
■ An ultra-compact size.
■ A requirement of custom electronics and complete
■ The availability of a USB version for initial application
Inertial Navigation System
MEMSIC (Andover, MA) has announced the INS380

■ A probe board operating temperature range from - 35°
for Hydraulic Valves
Hoffmann + Krippner (Frisco, TX) has announced a family
of robust and customer-specific hydraulic valve position
sensing solutions used in a range of industries such as oil &
gas, power generation, or wherever a precise valve position
in hydraulic applications is required. Features include:
■ LVDT sensors fitted into existing hydraulic valve
■ The use of electromagnetic coupling to measure the core
placement inside a valve.
■ The ability to be used as continuous position sensors.
■ The ability to be coupled to the valve anchor with a nonmagnetic core extension.
■ The ability to detect a measurement range from ± 1.2 to
± 20 mm.
■ Availability with either current or voltage output ( 4 to 20
mA/0 to 10 VDC).
■ A pressure sealed sensor.
■ An IP65 protection level (optionally higher).
■ A pressure-resistance up to 400 bar ( 5,800 psi).
■ The ability to withstand pressure
peaks up to 1,200 bar
( 17,400 psi).
■ An operating standard
temperature range from
- 25° to +85°C.
■ An extended temperature range
from -45° to + 125°C.
