Cryogenic Temperature Sensors
Germanium
-
Lake Shore germanium resistance temperature sensors are recognized as “Secondary Standard Thermometers” and have been employed in the measurement of temperature from 0.05 K to 30 K for nearly 40 years. Germanium sensors have a useful temperature range of about two orders of magnitude. The exact range depends upon the doping of the germanium element. Cryogenic temperature sensors with ranges from below 0.05 K to 100 K are available. Between 100 K and 300 K, dR/dT changes sign, and dR/dT above 100 K is very small for all models. Sensor resistance varies from several ohms at its upper useful temperature to several tens of kilohms at its lower temperature.

Sensors
-
To measure machinery or structural vibration, a transducer is needed to convert the mechanical motion into an equivalent electrical signal. Each sensor has distinct advantages in certain situations and limitations in other, so it is important to select the most suited transducer or sensor for your job. Equally, important is selecting the appropriate parameter of vibration amplitude for measurement. IRD® has a wide range of transducers and accelerometers available to help you obtain accurate, reliable data, whether your concern is vibration monitoring, analysis, or dynamic balancing.

Pulse Characterization Sensors
-
Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω

Pressure/ Vacuum Sensors
-
There are three different types of pressures that can be measured using Premier Electrosystems' Pressure Sensors: Gauge, Absolute, and Differential. Gauge pressure is the pressure measured relative to the ambient atmospheric pressure.A typical application for a gauge pressure sensor is to measure liquid levels in a vented tank using the difference in hydrostatic pressure and ambient atmospheric pressure. Absolute pressure sensors will give the result relative to zero (a perfect vacuum). This is useful in applications where there is a direct effect of altitude on the pressure being measured. Differential pressure sensors measure the difference in pressure between two points. Differential pressure sensors are often used to monitor airflow in HVAC applications.

Hyperspectral Imaging Sensors
-
HYPERSPEC® sensors are line-scanning instruments (sometimes called pushbroom) that collect reflected light through an image slit. One row of spatial pixels is collected per frame as motion occurs, with each pixel containing full spectral data. Motion can be accomplished in two ways: either as an airborne deployment (UAV, aircraft, or satellite) or stationary (where motion is accomplished beneath the sensor, such as a food inspection line). A third option is also available where pan-and-tilt or rotary stages allow a fixed-location sensor to scan a stationary object (such as a piece of artwork, or a mine face for geological applications).

Force Sensors
-
Piezoelectric force sensors, respectively piezoelectric force transducers or load cells, are perfectly suited for the precise measurement of compressive and tensile forces, both in highly dynamic applications and in quasi-static processes. In universities and industry, for basic research or quality assurance: exact data is always essential in order to measure force characteristics and make processes more cost-effective. Thanks to their rugged design, piezoelectric force sensors from Kistler keep precise track of quasi-static and highly dynamic force processes, even when conditions are difficult. Our force sensors can also handle simultaneous measurements of multiple orthogonal force components.
