Miniature Liquid Point Level Sensor

With its precision thermal sensing capabilities, the new next-generation miniature Model AS—LLE Liquid Point Level Sensor from FCI Aerospace (San Marcos, CA) offers a solution to detecting and alarming liquid level for tanks, reservoirs, sumps and gearboxes in commercial and military fixed wing and rotary aircraft. The AS-LLE Point Level Sensor can be used with most any liquid, including water, oil, hydraulic fluid, coolants, and more. Its titanium (Ti 6AL-4V, per AMS 4928) construction ensures it is rugged, lightweight, and corrosion resistant.

The Model AS-LLE Liquid Point Level Sensor is designed to be installed within the vessel itself. It operates based on an excitation current of 75mA. (ON for 30 seconds, OFF for 120 seconds), which delivers an output signal that corresponds to tank or reservoir level. The Model AS-LLE sensor’s body is designed to fit and go anywhere with a barrel-shaped body that’s only 1.36 inches (34.54 mm) long with a 0.625-inch (15.87 mm) diameter and weighs 1.6 oz (45g).

Power Clamps

Destaco (Auburn Hills, MI) is pleased to announce the launch and availability of its Model 84A40-1/84A50-1 Power Clamps. Despite their very compact double-arm design, these pneumatically powered clamps produce high force and tolerance compensation for firmly holding sheet metal together during various critical assembly applications, such as welding. The standard opening angle of the clamp is 90 degrees, but the opening angle of both arms is independently adjustable.

Three different sets of arms are available for the smaller 84A40-1 model and four for the 84A50-1. As with the Destaco 82M-3E and TCC-2E Power Clamp series, the new double-arm power clamps have two-part sensing and are available in three different sensor variants, such as PNP and NPN. The closed design of the clamps also means that they are sealed from external contamination and can be used in harsh operating environments. Lifetime lubrication makes the clamps practically maintenance-free.

Xeon D-based Single Board Computer

Aitech (Chatsworth, CA) released its latest security-enabled SBC (single board computer) featuring up to 16 lanes of PCIe to handle increased data processing requirements, while protecting the board from data attacks and cyber threats. The new C878 is a 3U VPX board that provides Intel Xeon D level processing in a rugged, industry-standard form factor. Equipped with double the Gen3 PCIe Data Plane lanes as Aitech’s C877, the rugged SBC was specifically designed using a modern, high-bandwidth bus architecture.

The C878 uses the same cybersecurity architecture as the C877—Aitech’s proprietary AiSecure—to provide secure transmission of sensitive data. Intel security includes Trusted Platform and Secure Boot as well as a BIOS Guard based on TXT TPM 2.0 and BIOS security. The onboard SATA SSD, up to 1 TB, supports write protection, secure and quick erase in addition to disk data encryption using AES 256 keys. A battery-backed tamper detection signal ensures system level protection.
