Differential Hall Switch for Position Sensing: One-chip Solution for Gear and Pole Wheel Scanning


iC-MZ is an integrated device consisting of a differential Hall switch with back-end complementary line drivers. The two integrated Hall sensors are set 2 mm apart and sense the difference in magnetic field. Magnetic DC fields are not evaluated; this means that besides the direct scanning of magnetic pole wheels with an additional bias magnet ferromagnetic gear wheels can also be detected. The magnetic input frequencies range from DC to 40 kHz. Magnetic DC fields of up to 500 mT are tolerated.


A magnetic difference in signal of 5 mT is sufficient to switch the outputs. The output drivers are RS422-compatible. Their output characteristics are adapted to the characteristic impedance of long lines in order to minimize reflections at the end of the line. With a supply voltage of 24 V a driver current of at least 200 mA can be supplied. The supply voltage ranges from 5 to 36 V ...

Signal Calibration and Temperature Compensation for Wheatstone Bridge Sensor Application


November 5, 2007 - Microbridge Technologies, Inc. has introduced the MBW-303 Wheatstone Bridge Offset Conditioning Network. The Conditioning Network is comprised of four eTC Rejustors (re-adjustable resistors), the world's first fully analog, passive electronic Temperature Compensation (eTC) dividers, configured in a Bridge. Designed for Wheatstone bridge sensors in automotive, healthcare, consumer, and instrumentation markets, this single chip solution compensates for offset errors and offset drift in a Wheatstone bridge, solving the problem at the source.


The MBW-303 simplifies the design process allowing sensor offset calibration and temperature compensation after final assembly, which negates all cumulative errors associated with the assembly processes, such as manufacturing tolerance errors, error introduced by stress, etc. Dynamic adjustment provides cost and labor savings and the networks' re-adjustability reduces re-work ...

Handy Cylinder Pressure Meter for Engine Diagnostics


The new engine peak meter Type 2516A10 from Kistler is a user-friendly instrument for measuring cylinder pressure. It is ready for immediate use without set up on the engine. This battery powered meter provides important measurement data for engine diagnostics directly at the point of use. It measures the peak pressure and calculates the pressure curve from an adjustable number of pressure cycles (pressure/time). The numerical measurement data is shown instantly after measurement on the large LCD display. Changes in both the peak pressure and the overall variation in pressure can be detected and recorded with the included software. It is also possible to compare pressure curves and peak pressure values with earlier measurements.


The well proven piezoelectric pressure sensor Type 7613C is used for measuring the pres-sure at the indicator valve. This robust sensor is characterized by its high degree of accuracy and long-term stability, and can be readily used on the indicator valve, even at high temperatures ...
