8 Channels Thermocouple, LV A/D
TC1
-
A thermocouple is a temperature-measuring device typically consisting of two dissimilar conductors that contact each other at one or more spots. It produces a voltage when the temperature of one of the spots differs from the reference temperature on other parts of the circuit. Thermocouple temperature sensors are widely used for measurement and control, and can also convert a temperature gradient into electricity.

Modular Mounts
M-SWITCH
-
The M-Switch series of adjustable, modular mounts are designed to redirect a horizontal interferometric set-up to a vertical one. This vertical orientation can help reduce distortion effects commonly found from clamping, and reduce alignment time. There are 4 primary versions of hardware designed to enable testing of mirrors, windows, lenses and lens assemblies. Holding of the part under test can be done with a variable 3 arm mount (for flexibility) or our kinematic mount (for high volume). Reference mirrors can be supplied with a variety of flatness and coating specifications to match your application needs.

Instrumentation Amplifiers
-
Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present.

True RMS RF Millivoltmeter
3440A
-
The 3440A measures the true rms of low level RF and microwave signals to over 1GHz. High rms accuracy, traceable to NIST, is assured regardless of waveshape. Common calibration errors are eliminated through temperature compensation of the probe detector diodes; double shielding protects the interchangeable probes from rough handling and pickup. Relative gain or loss measurements are simplified by a 0 dB reference adjustment. DC output proportional to the ac input is provided for analog recorders and to allow operation as an ac-dc converter.

Rotational Flow Demonstration Kit
-
The rotational flow demonstration kit detects the rotational position using the MCU’s on board data transfer controller (DTC) function, a form of state machine, while the MCU’s core is in stop-mode state. This ensures that the average power consumption is kept as low as possible, with IAV (average current) at 4.5 microampere (μA) and a 32 sample burst per second. The flow demonstration kit senses the flow direction and volumetric flow rate of water and gas, and can also detect reverse flow. The demonstration kit is applied using an active inductive method. Two coils are used to sense the rotational position of a part-metalized disk, and a third coil is used to generate a reference signal.

Seismic Transducers Calibration System
-
Calibration of the seismic sensors should be conducted in the low-frequency domain, which means, that the relative method used for calibration of the vibration transducers is not applicable since it does not guarantee the required accuracy level. The problem is that the reference accelerometers have uneven AFR characteristic in the low-frequency domain. Thus, calibration of seismic transducers requires implementation of a different approach.
