Make Your Own Plug-and-Play Load Cell System and Eliminate Costly User Errors


It is advantageous to have an efficient instrument that can automatically identify the load cell that is being attached to it and self-install the proper calibration data. When a new load cell is connected to the instrument, the appropriate calibration factors need to be installed in the instrument. Manual data entry or selecting from a database of stored calibration parameters introduces the possibility of user error. Loading the wrong parameters for a load cell, or corrupting the existing calibration data can lead to erroneous results and costly re-calibration expenses. An easy way to make a plug-and-play load cell system is presented in this paper.

IEEE TEDS 1451: “Plug-and-Play” or “Plug-and-Pray”?


The IEEE TEDS 1451 specification is an attempt to provide an industry standard Transducer Electronic Data Sheet which contains the necessary sensor gain factor in a memory location that can be automatically read by the instrument whenever a new sensor is attached. This paper addresses some of the difficulties and the solutions proffered by various companies in using IEEE TEDS for the calibration of the sensor with the instrument.

Protecting One’s Investments by Adhering to the CANopen Standard


CAN in Automation (CiA) offers a software tool to test devices for conformance to the higher-layer protocol CANopen. Also, the CiA international users’ and manufacturers’ group certifies CANopen devices with the help of this tool. The CAN-based higher-layer protocol CANopen is used in many different application areas, e.g. in machine building, in medical technology, in rail vehicles, in building automation and in commercial vehicles. Error-free communication, the base for liability exclusion and customer retention, is only possible if the interfaces have been implemented correctly.

Modelling and Experiments on a Quartz Crystal Resonator Sensor for Conductivity Measurements

of Low-Concentration Ionic Solutions


The monitoring and control of the electrical parameters of ionic solutions have different applications in industry and are particularly important in medical and biochemical studies, where ionic solutions are commonly used. This paper analyzes the effect of the conductivity of a low-concentration ionic solution on the resonant response of a Quartz Crystal Resonator (QCR) sensor with asymmetric electrodes put in contact with the solution. A model of the QCR sensor is presented, and experimental results obtained with a 6-MHz sensor exposed to low-concentration solutions of NaCl in water are reported. The model and experimental results are in very good agreement throughout the explored conductivity range between around 10 and 200 mS/m.

Surface Modified TTO Thick Film Resistors for NH3 Gas Sensing


Ti0.8Sn0.2O2-Titanium tin oxide (TTO) compound was prepared by using mechanochemical processing. AR grade TiCl3.2H2O (0.8 M) and SnCl4.5H2O (0.2 M) were mixed followed by calcination and ball milling. As prepared TTO was then used as starting material to fabricate the sensors in thick film form. Thick films were prepared by screen-printing technology on glass substrate. The dipping technique was used to obtain surface-cupricated TTO films in which copper was incorporated as additive. The thick films so obtained were fired at 550oC. The characterization of the films was done by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The gas response measurements were carried out as function of operating temperature (200-4000C) for different gases. These films were found to be most sensitive to NH3 gas. Surface cupricated film showed high gas response, fast response and quick recovery to NH3 gas. The result indicated that Cu modification would be responsible for improving stability and gas response of the sensor. The film dipped for 10 minute was observed to be most sensitive to NH3 gas at an operating temperature 300oC.

New Ѕ" Preamplifier with Gain, Filtering and TEDS for Automotive and Aerospace Noise Source Identification and In-Cabin Testing


September 8, 2006, Depew, NY, USA - PCB Piezotronics, Inc. introduces a new model to its line of acoustic products. Model 426A11 is a 1/2" preamplifier that operates from ICP® Sensor Power. The preamplifier allows the user to select 0 or +20 dB of gain and either a 20 Hz (-3dB) High Pass Filter or A-Weighted filter output response, in lieu of flat unfiltered response, via two switches, located on the external diameter. An overload detector senses both polarity overload signals in front of the filters. The unit comes standard with TEDS and is programmable upon request.


Model 426A11 preamplifier includes both A-weight and selectable "High Pass" filter, for automotive or aerospace cabin testing requirements. The "A-weight" filter attenuates signals less responsive to the human ear, normally below 1 kHz and above 4 kHz. This filter represents how the human ear perceives that sound. To make the cabin less noisy, a random incidence microphone (such as PCB Model 377B20), designed to measure sound from different angles of incidence, along with A-weight filter, is the choice of test equipment ...

Flow Research Study Finds Shift to Non-Contact Temperature Sensors


Wakefield, Massachusetts — A new research study finds several important shifts occurring in the temperature sensor market. The study, called The Market for Temperature Sensors in the Americas, 2nd Edition, was researched and published by Flow Research. The temperature sensor market in the Americas totaled $620 million in 2005, according to this study. Revenues from sales of temperature sensors in the Americas are projected to increase at a compound annual growth rate (CAGR) of 4.2 percent through 2010, when they are expected to reach $760 million.


One important technology change is the shift away from contact temperature measurement to non-contact measurement. This involves a shift away from thermocouples, RTDs, and thermistors to infrared thermometers and fiber-optic temperature sensors. Infrared thermometers are a form of non-contact temperature measurement, while fiber-optic temperature sensors have both contact and non-contact varieties ...
