GAPS (General Aerospace Proximity Sensors) and HAPS (Harsh Application Proximity Sensors) sensors from Honeywell are now available through Powell Electronics. These feature Honeywell’s patented integrated


health monitoring functionality, however they have some technical differences that allow them to be used in various aerospace applications. The GAPS series are configurable, non-contact,


hermetically sealed devices designed to sense the presence or absence of a target. They can be used in less harsh areas of application with some differences of electrical and environmental characteristics when compared to HAPS. HAPS


Aerospace Proximity Sensors are configurable, non-contact, hermetically sealed devices designed to sense the presence or absence of a target in harsh duty aircraft applications. The GAPS and HAPS series proximity sensors provide on/off outputs and can be configured with


an optional health monitoring output to the host system. The sensing mechanism is based on the familiar Eddy Current Killed Oscillator (ECKO) principles. However, Honeywell has also designed and implemented the patented FAVCO (Fixed Amplitude Variable Current Oscillator) technology, which enables the sensors to have the health monitoring (IHM) features. Both series have a circuit that can detect any internal failures and display a fault output instead


of a false positive or false negative. Additional features include an operating temperature range of -55˚C to +115˚C, a vibration resistance of up to 20G (GAPS series) and up to 90G (HAPS series), a supply voltage of 12Vdc up to 32Vdc, and a target response time of <5 milliseconds.

Hottinger Brüel & Kjær (HBK) has expanded the interface options available for its WI and WA inductive displacement sensor series, introducing models with an IO-Link interface, alongside existing industrial interface options. The Miniature


displacement sensors WI with measurement ranges from 2-10mm feature an outer diameter of only 8mm. The WA series offers a variety of configurations, enabling adaptation to any measurement task. This includes pressure-resistant versions, probe- type sensors, loose plungers and several cable outlet options suited for different mechanical environments. The loose plunger variants are available with measuring ranges of up to 500 mm. HBK’s three new inline amplifier modules come


with 0–10 V, 4–20 mA, or IO-Link outputs. These amplifiers improve linearity to just 0.1% and provide fully calibrated measurement chains. The digital IO-Link versions transmit measurement values in millimeters immediately once connected to an IO-Link master. The versions with IO-Link interface featuring Bessel- or Butterworth filters, and calibration results can be


stored directly within the sensor if required.

New from ifm, PQ Cube is a rugged and smart pressure sensor designed for vacuum grippers, air filters, and other challenging industrial environments. This features a smart installation design and


clear 1in TFT display. Its IP65 housing, durable brass sockets, and proven precise measuring cell work together to deliver consistent results, making it suitable for pneumatic applications. A built-in installation wizard streamlines commissioning so teams can get up and running faster. For applications that call for differential


pressure, the PQD version of the Cube measures the pressure difference across components such as air filters. In the version without a mounting adapter, one process connection routes downward and the other to the rear. In the version with a mounting adapter, the rear connection is also redirected downward, simplifying integration in tight spaces.

rugged and smart pressure sensor launched Every PQ Cube communicates over IO-Link 1.1 (COM 3), making parameter


setting and condition monitoring simple across the IO-Link infrastructure. Users can choose from versions with two switching outputs (DC PNP/NPN) or a configuration combining one switching output with one analogue output offering 4...20 mA, 0...10 V, or 1...5 V. Measuring ranges span from -1...0 bar through -1...10 bar, with options in bar and psi to suit applications worldwide. With a choice of G1/8 and NPT1/8 process connections,


M8 and M12 connectors, and switch point accuracy down to less than ±0.5% on selected versions, the PQ Cube adapts to a wide range of machine designs. It also pairs seamlessly with ifm’s moneo|configure free software and IO-Link masters for straightforward setup and ongoing management.

viBration sensor


designed for naval applications


Built around high-performance piezoelectric technology, the Sensonics QZA accelerometer design originated during the late Cold War submarine programme era and remains a core part of Hull Vibration Monitoring Equipment (HVME) fitted to Royal Navy vessels, as well as other NATO navies. Its primary role is to measure how much


vibration energy is present in the hull and machinery structure, feeding that data into the vessel’s HVME system so crews can understand and manage their acoustic footprint. The condition of the machinery generating that vibration is part of the picture, but not the main purpose of the sensor. The QZA, available in several configurations,


is permanently mounted to the hull and machinery rafts using a heavy-duty, four-point flange system, engineered to maintain a rigid, high-fidelity mechanical connection even under the extreme shock loading a warship may experience. The sensor’s output is a


50μA/g constant current signal. By continuously monitoring both auxiliary


machinery and the main propulsion train, QZA sensors allow HVME systems to flag when vibration levels move outside expected limits.
