  • 16-Bit, 9-Channel PXI Programmable Resistor Module

    PXIe-2727 / 781986-27 - NI

    16-Bit, 9-Channel PXI Programmable Resistor Module—The PXI‑2727 is a test module that replicates the behavior of resistance-based inputs and outputs such as potentiometers, resistance temperature detectors (RTDs), voltage dividers, and bridge elements. The PXI‑2727 programmatically controls a series of relays to vary the resistance across each channel of an I/O connector. This function is well suited for simulating environmental conditions in hardware‑in‑the‑loop (HIL) validation. The software provides a simple user interface that accepts inputs in units of temperature or resistance and configures the resistance across each channel.

  • Earth Sensors

    Optical Energy Technologies, Inc.

    The earth sensor is composed of four thermopile-optical assemblies viewing four fields of view through a single 13.5mm cut-on optical filter/window, as is shown in Figure 1. Each earth sensor measures the attitude of the spacecraft relative to its axis. For Pitch and Roll attitude readout, two sensors mounted 90° apart around the spacecraft’s yaw axis are required, as is shown in Figure 1. Each sensor is mounted such that the lower edges of its fields protrude 10° below the nominal earth horizon at the orbit altitude. The output of each field is a D.C. voltage proportional to the earth radiance multiplied by the solid angle subtended by the earth in that detector’s field. Two additional detectors are used to correct for earth radiance variation as a function of season and position in the orbit. One of these fields views cold space continually, while the other is always below the earth horizon and thereby measures the earth radiance in the vicinity of the spacecraft’s position in the orbit.

  • Microwave System Amplifier, 2 GHz to 26.5 GHZ

    83018A - Keysight Technologies

    The Keysight 83018A microwave system amplifier is a compact, off-the-shelf amplifier designed for systems designers and integrators. This amplifier provides power where you need it to recover system losses and to boost available power in RF and microwave ATE systems. The ultrabroad bandwidth from 2 to 26.5 GHz allows the designer to replace several narrow bandwidth amplifiers with a single Keysight amplifier, eliminating the need for crossover networks or multiple bias supplies. The standard Keysight 83018A includes internal directional detectors for external leveling applications. With excellent noise figure relative to its broad bandwidth and high gain, this amplifier significantly improves system noise figure and dynamic range. The Keysight 83018A comes equipped with a low profile heat sink, an integral mounting bracket, and a two-meter dc power supply cable. Thermal characteristics and power supply design allow fast, easy integration into most measurement systems.

  • Valve Leak Measurement System

  • Gas Detection

    Bacharach, Inc.

    Gas detectors designed to help comply with ASHRAE 15 and 34, EN 378, and CSA B52 are to protect someone from entering a mechanical room with refrigerant concentrations that could be harmful to their health. These protection levels are outlined in the safety standards to be about 1000ppm, 8-hour TWA depending on the type of refrigerant being used in the equipment. The alarm set points, location and number of detection points outlined in the safety standards are typically insufficient for finding the more common, smaller leaks that add up to large annual refrigerant emissions, decreased efficiency and overall safety.

  • Platinum RTD Sensor - PT100 - 3 Wire 1 meter long

    Adafruit

    For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0C, thus the name PT100. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100's have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability.

  • Radiometer

    X1-1-RCH-116-4 - Gigahertz-Optik GmbH

    The X1-1 radiometer from Gigahertz-Optik features an RCH-116-4 detector and is ideal for measurement of the irradiance of high power LEDs in the UV-A and blue light range. The device can accurately measure irradiance levels of up to 40,000 mW/cm². One of the outstanding features of the RCH-116-4 detector is its proven concept of a passive radiation absorber coupled to a UV sensor. This provides stability even in high temperature and intense UV radiation environments. In addition to the passive radiation absorber, the device also has a cosine-corrected field of view. The sensor’s housing also serves as a handle. The battery-powered X1-1 optometer supports a usable dynamic range from less than 1 mW/cm² to 40,000 mW/cm² thanks to its high-end signal amplifier. It can be used to perform precise measurements of up to 5 standard LED wavelengths for which the detector was calibrated for active irradiance. In addition to the CW measurement function, the device also has a dose measurement function. The radiometer can be used with other detectors from the RCH series. e.g. for gas discharge lamps. Remote control of the device is possible via its user software and a software development kit is offered for integration of the device in the user’s own software.
