Many scientific and low light-level applications face challenges from thermal noise in the CCD sensor. Controlling this noise allows cameras to operate with long exposure times and provide greater pixel-by pixel accuracy. Because thermal noise decreased by 3 dB for every 6C drop in temperature, the best way to control thermal noise is to cool the image sensor as much as possible.

Loadstar Sensors has promoted K Suresh, who is experienced in taking products from the prototype stage to full scale manufacturing, to Vice President of Operations

Loadstar Sensors has appointed Art Koehler, who has thirty years experience in marketing process control systems, load cells and speciality transducers, as Director of Sales

Included among the new products are a new control unit for small machines, having two separated safety circuits for a sensor and an emergency stop; a control unit with two safety outputs and two sensor inputs; a non-contact sensor system with integrated safety output, control output and status LED; and coded magnet sensors with N/O and N/C contacts plus an additional N/O circuit for use as a control contact, in 3 different housing configurations, all featuring wide operating distance and misalignment values.

The Three Speed Dryer Blower is now available from Cleaners Supermarket

The D904I model, unveiled this week, is equipped with a motion sensor that allows users to swing the handset like a tennis racket or wield it like sword to control game play. D904I was made by Mitsubishi Electric Corp,

At the heart of the TorqSense sensor is pair of tiny, interleaved, comb-shaped arrays laid onto one end of a piezoelectric substrate. By passing an alternating voltage across the terminals of these arrays, surface waves are produced in the substrate. The waves are received by a similar array at the other end which converts them back into an electric signal.

Vega offers a range of rugged level measurement devices designed to withstand pressure shocks, abrasion, moisture, vibration, pollution and condensation. Tough housings protect the fully potted electronics from the moist, humid ambient conditions and the harsh cleaning processes typical of this industry. To measure up to the increasing demands on operational reliability, SIL (Safety Integrity Level) classified instruments are available.

"The sensor is totally encapsulated in a PFA jacket, sealing it against chemicals and vapors that are unsuitable for standard sensor models. With its tiny size and rugged housing, the Q12 is an ideal choice for caustic or washdown applications with serious space limitations."

The XR19L402/400 series offers different packaging and modem interface options. Both devices can operate in four different modes: active, partial sleep, full sleep and Power-Save. Each mode can be invoked via hardware or software. Upon power-up, the device is in the active mode where the UART and RS-485 transceiver function normally. In the partial sleep mode, the internal crystal oscillator of the UART, or the charge pump of the RS-485 transceiver, is turned off
