Model 4807A High Resolution Accelerometer

Measurement Specialties, Inc. (NASDAQ: MEAS) has just released to production its ultra low noise Model 4807A Accelerometer. This DC response accelerometer features micro-g resolution and offers an industry-first, remote auto zero function. The 4807A provides an amplified, signal conditioned output in ranges from ±2g to ±200g with a dynamic range of 98dB. This sensor incorporates a gas damped silicon MEMS sensing element with integral mechanical overload stops for shock protection up to 5,000g as well as a wide bandwidth from DC to 1500Hz.

Specifically designed for low level vibration monitoring, the 4807A can be used in diverse applications such as transportation testing, flight testing, machine control and structural monitoring. Its stainless steel, hermetically sealed housing ensures reliable operation in rugged environments while its ±2Vdc bias output is compatible with industry-standard instrumentation.  The Model 4807A features a Total Error Band of <2% with an excitation voltage range from 8 to 18Vdc. The <2 second turn on time of the 4807A plus a broad compensated temperature range (-40°C to +121°C) makes this accelerometer an “all-weather” sensor that can jump to life quickly in power-starved installations.

The IP67 rating of this accelerometer provides significant protection in high humidity environments and against liquid incursion. The optional detachable cable (340A), triaxial mounting block(AC-D02652) and convenient three channel DC signal condition/amplifier (101) facilitates ease of installation. Those wishing the remote auto-zero function would choose the 341A cable assembly. Each unit is packaged with an NIST traceable calibration certificate. These devices are EAR99 export compliant and warranted for a period of one year from date of shipment to original purchaser to be free from defects in material and workmanship.

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications.
