Sensonics has released the fully integrated PRI Series of proximity probes, offering a single probe assembly with direct processed outputs, which does away with a separate driver. Recent design enhancements

offer improved performance for less demanding OEM applications with operating temperatures up to 120°C such as industrial gearboxes, pump fans, blowers and hydro- generator applications. Meanwhile the 180°C rated standard XPR04 probes with separate drivers would be suitable for use on higher temperature machines such as turbines. Proximity probes play an

important role in machine shaft vibration, position and speed measurements, providing operators with critical information on the rotating plant dynamic performance and bearing condition. The high reliability of the

Sensonics probe is based on the lack of external driver and tuned cable assemblies. In contrast, coaxial connector interfaces are a major failure point on standard proximity probe systems because they are susceptible to the ingress of oil and dirt, which can result in intermittent connection through either improper installation or mechanical stresses. There are no cable length

restrictions compared to standard proximity probes, which are restricted to typically 5m and 9m due to the required tuned circuit between the separate driver and the probe. The PRI series has no such restriction and can drive long cable distances (>500m) to the connecting equipment. Using the same 8mm

diameter tip as the API670 proximity probes, the case body is available in the standard M10 and 3/8” UNF variants providing an easy retrofit option.


The Yokogawa MT300 digital high-accuracy manometer has been developed to cater for measurement needs across an increasingly varied market. Pressure sensors in consumer

goods and wearables, and their increasing use in such industries as automotive and medical, has led to the need for more precise pressure measurement for their development and calibration. The Yokogawa MT300 fulfills the measurement and long-term stability requirements of these advanced applications, with multiple models for gauge, absolute and differential pressures. The MT300 uses silicon-based

resonant sensor technology, offering the high levels of accuracy and stability required of an international calibration transfer standard. It has an absolute accuracy of pressure measurement of 0.01 per cent. Four models of the MT300 are

available for gauge pressure, covering ranges from 10kPa to

The UHD100T32 multi-terabit test system from Keysight provides analysis capabilities for data centre operators and network equipment manufacturers With mass deployment in

modern data centres, 100GE technologies have matured. Cloud service providers, communications service providers and network equipment manufacturers are now challenged with density and cost pressures on their test infrastructure. This typically leads to a

compromise in testing cycles and the use of test systems and methods that don’t allow for comprehensive quality control. The new UHD100T32 test

system from Keysight has a space-saving 1U box and users get the power of 3.2Tbps of line- rate test traffic from 32 ports of 100GE, a requirement to validate the performance of ultra-high-

3,500kPa. The absolute pressure model has a range of 130kPa, while the three differential pressure models have ranges from 1kPa to 700kPa. The instrument has a range

of applications, from pressure leak testing in a vessel to the air speed measurement of hair dryers. Depending on the model, measurement intervals down to 50ms are achievable, allowing the measurement of very rapid transient pressure variations, such as when using a differential pressure flow transmitter. When multiple pressure

variables need to be measured and recorded simultaneously, up to four MT300s can be interconnected and synchronised to a PC via GP-IB, USB or Ethernet.

❱❱ The MT300 digital manometer can be used singly or in combination with other instruments for a wide range of pressure measurement applications


❱❱ 100GB Ethernet (GE) test system helps data centre operators and network equipment suppliers meet density and cost-per-bit challenges

density devices like those found in modern data centres and in manufacturing use cases for full box tests in production lines. Designed specifically to

address the form factor and density challenges of data centres, the UHD100T32 test system provides users with the ability to validate 100GE performance, scalability and interoperability with confidence. With all fan-out speeds

(50/40/25/10GE) enabled, the UHD100T32 has the flexibility to test all speeds in a data centre fabric. It also includes technology for Layer 2/3 traffic generation and analysis

and RFC 2544 tests for benchmarking throughput and latency of devices. Optional routing protocols are

available for open shortest path first (OSPF), border gateway protocol (BGP) and intermediate system to intermediate system (ISIS) that allow users to emulate from control plane to data plane for convergence testing. A clientless operation via web

interface and modern “representational state transfer” (REST) application programming interface enable faster time to test and easy automation.
