Universal Frequency-to-Digital Converter (UFDC-1):

a Revolution in Analog-to-Digital Conversion


Toronto, ON, Canada, October 19, 2004 -SWP, Inc. announces a low-cost, high-performance, highly flexible Universal Frequency-to-Digital Converter (UFDC-1). It can be used for any frequency-time domain signal like standard ADC for analog signal domain. Now sensors manufacturers will be able simply integrate the UFDC-1 in microsystems and digital sensors in order to produce a serial output or bus capability and to target at a cost-driven industrial market.


This IC is a programmable, two-channel frequency-to-digital converter for use with any frequency, period, duty-cycle, time interval, phase-shift and pulse number signal. The UFDC-1 converts any frequency-time domain signal to digital and uses four patented conversion methods. It works in 16 measuring modes, one generating and calibrating mode. The UFDC-1 lets embed frequency-to digital conversion into smart sensors. Features: frequency range from 0.05 Hz to 7.5 MHz (120 MHz with prescaling); programmable accuracy from 1% to 0.001 %; non-redundant conversion time; quartz-accurate automated calibration; RS-232, SPI and I2C interfaces; master and slave communication modes; single power supply 4.5 - 5.5 V; current consumption at 16 MHz, 5V, 25 0C below 20 mA; operating temperature range (- 40 0C to + 85 0C); 28-lead Plastic Dual Inline Package (PDIP); custom design available.

TEDS Pressure Sensors


Depew, NY – The Pressure Division of PCB Piezotronics, Inc. offers pressure sensors and signal conditioners that support the TEDS (Transducer Electronic Data Sheet) IEEE P1451.4 standard. TEDS sensors are self-identifying transducers that contain fields that fully describe the type, operation, and attributes of the transducer, and are typically used in large channel count testing such as acoustic array applications.


The IEEE P1451.4 standard defines a mixed-mode interface that retains the traditional analog sensor signal, but adds a low-cost serial digital link to access a TEDS embedded in the sensor for self-identification and self-description. The embedded memory chip eliminates the need to manually input sensor parameters when configuring a system.  Users will be able to simplify sensor set-up, use, and maintenance, obtain calibration data, and eliminate manual data entry and error when using TEDS pressure sensors.

Microsystem Technology Breaks Mew Ground in Dew Point and Fluidic Metering


Villingen-Schwenningen / Munich - Microsystem technology breaks new ground in dew point and flow sensor technology. At Electronica 2004 (Munich, 9-12 November 2004) the Institute for Micromachining and Information Technology of the Hahn-Schickard Gesellschaft (HSG-IMIT), a R & D service provider in microsystem technology, will introduce a new type of sensor operating on thermal principles metering humidity or volume fluidics with a heated silicon membrane.


With the development of a thermal dew point sensor, the Institute rings in a new chapter in humidity metering. Manufacturing costs lie approximately 90 per cent below those of comparable precision dew point sensors. The microsensor with long-term stability fits into a match head and in borderline cases also meters more exactly than many standard sensors operating on optical or capacitive principles. The access period is currently less than 10 seconds. HSG-IMIT believes a reaction time of milliseconds possible. In addition the thermal dew point sensor can test and calibrate itself. Limitations as known from other sensors such as hysteresis or incorrect metering values due to conductive condensation do not occur here at all.

Vibration Spectrum Analyzer and Data Acquisition Module


The Datastick DAS-1258 is a small, lightweight peripheral that attaches securely to the back of a Palm handheld. When combined with Datastick software, the appropriate cable, and the user’s ICP® accelerometers, it becomes the first complete, PDA-based multipurpose instrument for vibration analysis and analog data acquisition for ICP accelerometers and other sensors. The DAS-1258 comes with Datastick Spectrum and Datastick Connection Lite software applications. The DAS-1258 can also accommodate low-power, non-ICP accelerometers such as those manufactured by Crossbow, and a wide variety of analog sensors for general-purpose data acquisition.


Vibration Analysis. When used with Datastick Spectrum software and ICP accelerometers or low-power, non-ICP accelerometers such as those manufactured by Crossbow, the DAS-1258 becomes a vibration analyzer displaying Fast Fourier Transform (FFT) snapshots in thirteen selectable ranges up to 5 KHz, at a single-sided-spectrum resolution of up to 1024 points, with nine windowing options. A Palm Tungsten T or C handheld is required for FFT displays.


Data Acquisition. When used with a wide variety of analog sensors or ICP sensors and the appropriate Datastick Connection software program, the DAS-1258 permits data acquisition in real time at lower speeds or in capture-and-review mode at moderate speeds. Datastick Connection Lite software is included at no charge.
