Cable-Free Noise Dosimeter helps prevent workplace hearing loss.

2016-01-22 14:31:06| Industrial Newsroom - All News for Today

Weighing 4 oz and measuring 3.3 x 2.1 x 2.1 in., shoulder-mounted dBadge2™ captures every metric needed to satisfy noise exposure regulatory requirements worldwide. Bluetooth® 4.0 allows exposure data, along with comments, to be emailed wirelessly from hand-held device and enables multiple dosimeters to be wirelessly controlled from distances of 100 ft or more away. Updated for viewing in real-time, exposure data provides device status and noise level information before and during sampling.

TMR Linear Magnetic Field Sensors exhibit ultra low noise.

2016-01-20 14:31:06| Industrial Newsroom - All News for Today

Respectively offering 30, 100, and 300 mV/V/Oe sensitivity, TMR9001/TMR9002/TMR9003 series are in-plane Tunneling Magnetoresistance (TMR) linear magnetic field sensors with ultra-low noise spectral density of ~150 pT/√Hz@1 Hz. Each model, supplied in 6 x 5 x 1.5 mm SOP8 package, utilizes push-pull Wheatstone bridge composed of 4 TMR sensor elements. Under 1 V applied voltage, power dissipation during operation is 20 µW.
