HIGH ACCURACY DIGITAL TEMPERATURE SENSOR M
MS Electronics improves temperature measurement
accuracy. The Smartec SMT172 is a complete digital ultra-low power, factory calibrated, high accuracy temperature sensor with pulse width modulated output signal. PWM output sensors offer have high noise immunity and high reference accuracy. They are easy to interface and easy to multiplex. The sensors output duty cycle is proportional to the measured temperature. Accuracy is 0.1 ºC in the range of -10ºC to 100ºC. Max temperature is 130ºC. When adding a RC network the sensor can also be used as an analogue sensor. Supply voltage range from 2.7 V to 5.5 V. This is the most energy efficient temperature sensor in the world with an average current of < 60uA or 220nA. Many different packages are available to suit the application including a 5 and 7mm stainless steel probe. To speed up development evaluation boards with USB and I²C Interface are available. Application are found in wearables, scientific, environmental, medical or industrial measurements. Contact MMS Electronics Ltd to discuss your application.

HBM’S ‘ALL-ROUNDER’ DIGITAL TORQUE TRANSDUCER
W
ith electric motors and drives now operating at significantly
higher speeds, electromobility testing poses a greater challenge for engineers working on R&D or production lines. To overcome this challenge, measurement specialist, HBM has launched the T40B torque sensor which delivers greatly increased revolutions per minute for a selection of measuring ranges of 1, 2, and 3 kNm - up to 23.000 rpm - making it ideal for many types of applications including test benches, end-of-line tests (EoL) and process monitoring. The T40B torque provides users with precise, reliable measurements first time, eliminating the risk of errors and the need for repeat tests, which can be costly and time consuming. The sensor has an integrated, magnetic rotational speed measuring system, enabling automotive engineers to test the efficiency of the drive train with a range of motor vehicles. It also operates with analog or digital interfaces making it compatible with different types of test bench systems.

THE SMART OPTION! T
with integrated electronics and an IP68 probe attached to a cable. The cable is up to 20 m long to ensure the probe can be lowered to the bottom of large tanks. The electronics unit is enclosed in a rugged stainless-steel housing with a thread for attachment, for instance on the tank cover. A line of LEDs integrated in the measuring head indicates the level at a glance. The sensor requires a 24 V DC supply. It can be used in ambient or media temperatures from -20 °C to +75 °C. Measured values are transmitted via a 4...20 mA output.

HYDROSTATIC LEVEL SENSOR FOR UP TO 20M E
GE has extended its DGC line of hydrostatic level meters, adding a new sensor for measuring liquid media levels up to 20 m. The sensor consists of a measuring head
he M18 “One for all” series gets smart and connected. The S5N series is the first important step in the complete renewal of the photoelectric sensor range from
Datalogic with the introduction of its new innovative ASIC and state of the art IO-Link smart sensor features. The range renewal is starting with the bestselling M18 tubular sensor line, made of S5,
S15, S50 and S51 series, now to be all integrated in new S5N line. This first step is the conversion from S50 to S5N, where all the current models will
maintain a full backward compatibility to avoid any problem with replacement in the huge installed base. The S5N sensors, with standard M18 flat tubular housing, keeps on offering the widest
range in its segment, with a complete choice of optical functions, axial or radial optics, cable or M12 connector, NPN or PNP with NO/NC outputs. But that’s not all, the new S5N with its new and unique ASIC technology will make this
M18 family the first tubular sensor family with IO-Link V1.1 and smart sensor profile on the market.

NEW LOW-COST RANGE OF SAFE AND HAZARDOUS AREA PIEZORESISTIVE PRESSURE TRANSMITTERS
T
he AMO M10 is a new low cost industrial pressure transmitter designed for general purpose pressure measurement. This sensor is rugged and durable, providing accurate measurement even under harsh
conditions, available in gauge, absolute and sealed gauge versions. The MPM489 model is the ATEX approved version certified to ATEX Exia IIC T4 Ga . The Diaphragm is the sensing element in these pressure sensors which is comprised of multiple layers
including a silicone substrate. The strain on which is determined using a diffused resistor network. Monocrystalline silicone is the low-cost material used in the manufacturing of these semiconductor based sensors. Silicone material displays excellent piezoresistive properties. When pressure is applied, the diaphragm flexes and causes a deformation in its crystal lattice which
ultimately modifies the band structure placed on the diaphragm and changes the resistivity of the material. Semiconductor resistors on the front side transduce this tension into resistance changes by means of the piezoresistive effect. Both models are constructed from stainless steel with a choice of grades to ensure application suitability.
Process connections and operating pressure ranges can be specified as can options for signal output type, diaphragm material and electrical connections. Every device is temperature compensated and calibrated and supplied with a traceable serial number and calibration certificate. The electronics incorporate a microprocessor based amplifier which means that there are no adjusting pots and therefore the electronics are very stable, especially in high vibration and high shock applications.
