HMB LAUNCHES BIT-RATECANFD


❱❱ The LZSE current transducer enlarges the measuring range with closed-loop Hall effect technology


ON-BOARD CURRENT MEASUREMENT


A new family of transducers are able to be mounted on printed circuit boards (PCBs) for non-intrusive, isolated measurements of DC, AC and pulsed currents from 100A to 200A nominal. The LZSR range from LEM


is based on ASIC technology and over a temperature range of -40°C to +85°C, the offset drift is much better than the previous generation of closed-loop Hall effect transducers working with traditional Hall effect chips.


An overcurrent detection


output is also offered as an option and can give an indication that a measured current is exceeding its expected value or can switch the power off in the event of a short circuit. The range is offered in a very


compact size and is particularly well suited to applications where low offset drift is important, such as in the latest string inverters generation on the AC side of 70kW to 120kW solar inverters.


BUILT TO STOP A TRUCK


Test and measurement company HBM has expanded its range of data acquisition modules with the launch of the MX471C with CAN FD (CAN with flexible data- rate) protocol. The module is part of the


industry standard’s QuantumX family, providing engineers with universal and flexible methods of integrating data acquisition systems into CANbus networks. CAN FD solves the bandwidth


limitation problem of classical CAN networks by allowing bit-rates higher than 1 Mbit/s. In addition, it supports payloads in CAN FD messages up to 64 bytes. Many automotive companies


make use of this increased bandwidth at low cost, which is especially required in today’s electric vehicles. The MX471 CAN FD module


allows the synchronous integration of up to four CAN networks and can be expanded as required. The module, when combined


with a data recorder and analogue measurement modules, is well suited for mobile vehicle tests and as a measurement gateway on test benches. With the channel in Recorder mode, any number of signals –


Bollard maker Heald has been testing its latest Matador range of fixed and rising bollards, proving that tailgating access points protected with a rising bollard really isn’t a good idea! Built to stop a 7.5T truck


travelling at 64kph (40mph), Heald’s hostile vehicle mitigation bollards meet the most stringent Centre of the Protection of National


Infrastructure (CPNI) and PA68 BSI standards. Tests performed by Heald


showed the bollard was capable of performing its hostile vehicle mitigation intentions by stopping a 7.2T truck at 80kph (50mph). Part of the test


specification is that the bollard should continue to operate, retracting and rising from the roadway even after the crash.

❱❱ The SomatXR data acquisition module for automotive CAN applications supports higher data rates and can be used for mobile and bench testing


such as vehicle speed, steering wheel position or brake command – can be acquired simultaneously with the analogue inputs of other QuantumX amplifiers and used to trigger data storage, for example. This reduces the need for


manually applied sensors in the BAUMER IS BUZZING OVER NEW


Sensor manufacturer Baumer has introduced a range of optical miniature sensors which raises the standard of precisely detecting previously challenging objects across a wide scope of applications. Slightly larger than a honey


bee with a housing size of 8mm, the 0200 range of miniature sensors provides reliable and excellent detection, even for such challenging objects as ultra-black, shiny, transparent or


small targets down to a size of 0.25mm diameter or width. The new sensors feature


SmartReflect, an integral light barrier without a reflector which enables safe object detection with a range up to 180mm and which also helps to optimise flexibility in machine and system design. Also, an innovative ambient


light algorithm ensures maximum immunity to ambient light, even with LED lighting or
