Make quality audio measurements with PCB's 48V
microphone system. Model 426A14, preamplifier
has a versatile, patent pendingmodular design
and mates with any IEC 61094-4 compliant
Models 352A71, 352A72, 352A73 and 352A74 are miniature teardrop ICP® accelerometers. The series features three different sensitivity options and a flexible twisted pair integral cable for easy routing. Flexible potting material adds strain relief where the cable exits the sensor. All the accelerometers are hermetically sealed in a titanium package. They can be powered by any ICP® signal conditioner or data acquisition system that includes 18 to 30 VDC and 2 to 20 mA of constant current.
Very small teardrop-shape
Flexible integral cable for easy routing in tight spaces
Hermetically sealed titanium housing
Three sensitivity options: 5 mV/g, 10 mV/g, 100 mV/g
IMI Sensors Launches Very High Temperature Charge Accelerometer with UHT-12™ Element
July 20, 2016 DEPEW, NY – IMI Sensors, manufacturer of industrial vibration
monitoring instrumentation, announced the release of Model 357A100, a very high
temperature differential charge accelerometer with a UHT-12™ sensing element.
IMI has developed the sensor to be used in the commissioning of nuclear power
plants, condition monitoring of power generation and aviation gas turbines and
machinery protection in very high temperature environments.
The new UHT-12™ crystal technology features:
· Absence of pyroelectric noise spikes up to 900 °F (482 °C).
· Sensitivity that remains more consistent over a wide temperature change.
· Shear mode crystals isolated from base strain & transverse measurement errors.
· No depletion of oxygen at high temperatures, thereby not requiring a vent or window in the housing.
IMI offers various differential charge amplifiers to support the launch of Model 357A100, including Models 421A3X, EX682A40 and 422M182. Additional information about IMI’s complete line of high temperature vibration sensors can
be found here.

Made Tough: Test Where Other Microphones Fail
PCB's new Model 130A24, ½" ICP® Water and Dust Resistant Prepolarized Array Microphone system can make measurements in harsh environments, prone to contaminants such as:
With an IP-55 rating, this system is ideal for applications, such as tire well testing, brake noise testing, and noise source identification.
IMI Sensors has developed the 603 Series, a line of ICP® accelerometers for industrial vibration monitoring applications. All of the sensors in the product line include a shear-mode ceramic element housed in a rugged hermetically-welded stainless steel enclosure. All models include case-isolated electronics to eliminate noise issues.
