Carbon dioxide sensor

Sundae’s K-33 CO2 sensor assists scientists and environmental and agricultural engineers who need to measure indoor and outdoor changes in carbon dioxide levels.

The K-33 is a low-power sensor that measures carbon dioxide, temperature and relative humidity. Up to 5,400 data points can be stored in its on-board memory and downloaded later for analysis. It also features a sleep mode in which the sensor can be powered by four AA batteries and can remotely record atmospheric conditions for weeks or months at a time.

For rapid application prototyping or scientific experiments, an inexpensive open-source software development kit is available for the K-33 sensor. The software allows the user to read the sensor data log, as well as program dozens of parameters for custom applications.

Runout and concentricity inspection system

Johnson Gage has introduced the Centrax runout and concentricity inspection system for verification of cylindrical runout or concentricity in manufacturing or inspection applications. The JCR-1 model incorporates precision datum rolls, an upper tension roll assembly and integral axial stop pins to ensure proper part staging and absolute gage accuracy.

To accommodate part specific and universal applications, the unit features an adjustable indicator mounting arm with fine-adjustment positioning and variable CMM tee-slot mounting stand. It is equipped with a belt drive to remove operator influence and to simplify operation while increasing gage reliability and repeatability. Typical applications for the Centrax include finished and semi-finished fasteners and fittings, screw machine products and high-precision medical parts.

Safety trip alarm

Moore Industries’ STA safety trip alarm performs as a logic solver and acts on potentially hazardous process conditions. It warns of unwanted process conditions, provides emergency shutdown and provides on/off control in safety-instrumented systems.

The four-wire STA accepts a signal input from transmitters, temperature sensors, resistance and potentiometer devices, and a wide range of other monitoring and control equipment.

The STA provides three fail-safe alarm outputs. Two are configurable process alarms that trip when a monitored process variable falls outside of user-set high and/or low limits. The third alarm is a non-programmable, latching alarm that is activated if any internal faults are found by the STA’s extensive internal diagnostics.  This fault relay is also triggered if the input is faulty or broken. 

The STA features failure modes, effects and diagnostics analysis-certified safety data to be used by a competent functional safety practitioner to determine the unit’s applicability as a logic solver in specific safety-related applications.

Inspection software

Renishaw has introduced version 2.02 of its OMV Pro software that includes more advanced coordinate measuring machine-style capabilities, with an extended range of geometric dimensioning and tolerancing functionality.

The OMV Pro 2.02 also has the ability to work with multiple alignments in a single program, an advantage in working with multi-axis machine tools.

The OMV Pro 2.02 allows users of machine tool touch probes to quickly verify the accuracy of freeform and prismatic parts without removing the part from the machine. The software includes simulation capability, enabling users to see exactly what was cut and make corrections before the part leaves the machine.

Linescan camera

Sensors Unlimited has announced that high-resolution, shortwave infrared (SWIR) area and linescan cameras are being used to improve the manufacturing yield of photovoltaic (PV) cells. SWIR technology is suited to monitor the quality of solar thin films, as well as concentrated PV and crystalline cells, to maximize efficiency of the solar cell manufacturing process through final assembly of the completed modules.

The SWIR cameras, which operate between 0.9 to 1.7 microns, are ideal for inspecting silicon boules and wafers due to the material’s transparency beyond 1.2 microns. They reveal voids in silicon boules, bricks and ingots before they are sliced into wafers to produce mono and multi-crystalline solar cells.

SWIR cameras can also spot saw marks on the opposite side of a silicon wafer or defects inside the material.

Viscometer

The m-VROC from RheoSense is a microfluidic viscometer featuring an enclosed system complete with required hardware. The portable design allows the system to be implemented on or off the process line.

The m-VROC requires the smallest sample volume of 50 ml, which is the target for protein and other biological formulations.

Optional temperature control is provided, and an optional purge air supply prevents condensation inside the chamber when operating at low temperatures.
